About VoIP Monitoring Manager

Avaya VoIP Monitoring Manager is a Voice over IP (VoIP) Quality of Service (QoS) monitoring tool. It enables you to monitor and review the quality of a call on an Avaya VoIP network. Avaya VoIP Monitoring Manager allows you to view the QoS data (such as Jitter, Round Trip Time
(RTT) and Packet Loss) experienced at the endpoints and during a session. The QoS data
displays in real-time or for previously active endpoints. With this information, you can begin to troubleshoot and isolate problems.
If you are new to using the VoIP Monitoring Manager, the following information explains what you can do with this tool.

Search for Endpoints

You can search endpoints active from a specified time in the past or within a date range. The Advanced Search options enable you to narrow your search to match phone numbers, SIP user
names, network addresses, or QoS level.

View Reports

Once you have completed your search, you can select one or more endpoints in a session and view the associated reports. The reports display the QoS data for the selected endpoints. This is particularly useful for monitoring media gateways or locating problems at a particular endpoint.
Since you can view reports for endpoints involved in a session, this information will assist you with determining problems that occur between two endpoints or in an isolated area of the network.

Export Reports

You can export the report data to a comma separated value (csv) file. You can open this file in most database and spreadsheet programs such as Microsoft Excel. Exporting the data to a spreadsheet enables you to manipulate the data so you can create your own reports..

Generate Automatic Alarms

You can generate Simple Network Management Protocol (SNMP) traps/alarms, which allow the VoIP Monitoring Manager to alert you when the Jitter, Round Trip Time or packet loss reaches certain levels. This assists you to routinely monitor the network and troubleshoot problems.

About VoIP Monitoring Manager Client

The VoIP Monitoring Manager (VMM) Client provides the graphical user interface (GUI) to view the VMM data. The VMM Client does not communicate with the VMM RTCP Monitor, does not use SNMP, and does not communicate with the database. The data that is displayed is gathered from the VoIP Monitoring Manager (VMM) Server.
The VMM Client may be installed on the same machine as the VMM Server, or it may be installed on another PC on the network. It is possible for the VMM Server and the VMM Client to communicate over a dial-up connection.

About VoIP Monitoring Manager Web Client

The VoIP Monitoring Manager (VMM) Client can run as a web application in a browser. This is useful if you only have the VMM Server installed. To run the VMM Client as a web application, the following requirements must be met:
The VMM Server needs to be running a web server. The Apache web server is
automatically installed on the server when the VMM Server software is installed.
The web server must be configured to publish the file to the following VMM installation
path:
C:\Program Files\Avaya\VoIP Monitoring Manager\jars\ClientApplet.htm NOTE:
The server installation will apply this configuration.
The PC you will use to access the VMM Server must be able to connect to the VMM
Server via a web browser and have the following software installed:
Microsoft Internet Explorer 6.0 or later  Sun Java 2 Runtime Environment, SE v1.4.2_06.
If you run the web client, you will not have access to all the functionality available in the VMM Client application. For example, you will be unable to copy and connect to a new server. For more information, see Starting VoIP Monitoring Manager Web Client.

About VoIP Monitoring Manager Server

The VoIP Monitoring Manager Server acts as a proxy between the database and the VoIP Monitoring Manager Client. It manages connectivity to the database and provides an interface to configure the VoIP Monitoring Manager RTCP Monitor. The main purpose of the VoIP Monitoring Manager Server is to reduce the amount of traffic to the VoIP Monitoring Manager Client by performing large data downloads and extensive processing of the MIB data stored on the RTCP Monitor.
The VoIP Monitoring Manager Server is a Java application that runs as a Windows service on the same PC as the RTCP Monitor. The VoIP Monitoring Manager Server can reside on the same PC as the RTCP Monitor, or it can reside on a separate PC.

Components of VoIP Monitoring Manager

The VoIP Monitoring Manager (VMM) application consists of the VMM RTCP Monitor and the VMM Server, which accepts connections from the VMM Client. If you only have the VMM Server installed, you can run VMM Client as a web client.
To ensure VMM will run correctly, you must perform the following steps:
Configure the Switch Administration Forms on Avaya Communication Manager.  Install a Windows SNMP Agent on the server (if not installed already).  Install the VMM Server on to the network.

The components and their relationship are described in more detail in the following links:
VoIP Monitoring Manager Server  VoIP Monitoring Manager RTCP Monitor  VoIP Monitoring Manager Client  VoIP Monitoring Manager Web Client  Database

About Licenses

VoIP Monitoring Manager requires licenses that you must purchase from Avaya. You can purchase these licenses in sets of 2000 phone endpoints and 40 media gateways. The Avaya licenses are managed by the WebLM server, which is provided with VoIP Monitoring Manager.
By selecting Help>About in the VMM Server window or the VMM Client, you can view the following information:
the number of licenses purchased  the number of phones at the local server. This number represents the phones that
reported to VMM in the last 28 days. This number will increase if you move phones (for example, change extensions or IP addresses). In this case, these phones appear to be new endpoints to VMM. Since there is a 30-day grace period, this will not be a problem.
the number of phones at the local server that exceed the license (that is, the number of
phones that are unlicensed). If greater than zero, this number is displayed in red. This can occur if you have only one monitor connected to the WebLM License Server, and you have more phones stored in the database than licenses purchased.
the number of media gateways at the local server. This number represents the media
gateways that reported to VMM in the last 28 days.
the number of media gateways at the local server that exceed the license (that is, the
number of media gateways that are unlicensed). If greater than zero, this number is displayed in red. This can occur if you have only one monitor connected to the WebLM License Server, and you have more media gateways stored in the database than licenses purchased.
Each VMM RTCP monitor periodically checks the number of endpoints it knows about and requests/renews the licenses for them. If there is more than one RTCP monitor and the total number of endpoints known exceeds the number of licenses, the RTCP monitor that requests licenses first will get its licenses. The RTCP monitor that requests licenses last will be denied licenses. If you enter the 30-day grace period because license limits were exceeded, the About dialog box will appear every time you start the VMM Client or open the VMM Server window. If you exceed the 30-day grace period, VoIP Monitoring Manager Server stops collecting RTCP data.
Avaya provides a 90-day trial version of VoIP Monitoring Manager. After 90 days, VoIP Monitoring Manager stops collecting RTCP data. You have the option of purchasing the VoIP Monitoring Manager license key from Avaya to fully activate the VoIP Monitoring Manager beyond the 90-day trial period. When a license key is purchased, an instance of WebLM License Server is required to manage the license key.
Contact your authorized Avaya Sales Representative to purchase additional VMM licenses.

Installation Checklist

Installation Checklist

The VoIP Monitoring Manager Server (VMM Server) needs to be installed on the VoIP network. Before you install the software, you need to configure the Switch Administration Forms on Avaya Communication Manager.
1. Configure Switch Administrator forms.
You need to configure the System-Parameters IP-Options Form and the IP-Network­Region Form to send RTCP reports to the RTCP Monitor.
2. Make one port 1099.
The VMM Client and Server communicate using Java Remote Method Invocation (RMI), and uses port 1099 as its default port on the machine running the VMM server. If port 1099 is not available, another port must be made available.
3. Check for Windows SNMP Agent.
The SNMP Agent must be installed for the VoIP Monitoring Manager Server to function. You can check if the Windows SNMP Agent has been configured to run at startup automatically. The installation also checks to see if the Windows SNMP Agent is installed.
If the Windows SNMP Agent is not installed, the Add/Remove Windows Components starts automatically and you are be prompted for the Windows 2000 CD location to install the Windows SNMP Agent.
4. Check for a valid SNMP Community ID.
You must set an ID with the correct privileges.
5. Configure SNMP agent for sending traps.
Although SNMP is installed and running, it does not send the required traps until you configure it.
6. Install VoIP Monitoring Manager.
Insert the CD into your drive and follow the instructions.
7. Connect to a database.
When you first install VoIP Monitoring Manager, you need to connect the VMM Server to a database.
Solving Installations Problems: If you are experiencing difficulties running the application after installation, the following checks may assist you:
Check Windows SNMP Agent is Running  Check for a Valid Community ID
5
Page 14
Avaya VoIP Monitoring Manager Reference

Configure IP-Network-Region form

You must configure two Switch Administration Forms (SAT) on Avaya Communication Manager to send RTCP reports to the RTCP Monitor. These forms are called the ip-network-region form and the system-parameters ip-options form.
Configuration for the ip-network-region form
Set the RTCP Reporting Enabled? field to y (yes).  Set Use Default Server Parameters? field to y (yes). This indicates that this network
region uses the default values specified previously on the system-parameters-ip-options form as well.
Why you might not want to use the default parameters?
Multiple VoIP Monitoring Manager Servers might be installed on a large system in order to reduce the network traffic between a set of endpoints and the RTCP Monitor (for example, low bandwidth link between endpoints in one network region and a remote RTCP Monitor). The network traffic due to RTCP reports being sent from the endpoints to the RTCP Monitor is usually low, less than 40 bytes per second per currently active VoIP call (RTP session). Therefore, it is usually unnecessary to have multiple RTCP Monitors.
If multiple VoIP Monitoring Manager Servers are installed on the system, then the endpoints in each network region can be configured to send their RTCP reports to different RTCP Monitors. To configure the endpoints in each network region to send their RTCP reports to different RTCP Monitors, perform the following steps:
Set Use Default Server Parameters? field to n (yes).  Specify the IP address of the Windows 2000 PC running the VoIP Monitoring Manager
Server for that network region.
6
Page 15
Avaya VoIP Monitoring Manager Reference

Configure System-Parameters IP-Options Form

You must configure two Switch Administration Forms (SAT) on Avaya Communication Manager to send RTCP reports to the RTCP Monitor. These forms are called the system-parameters ip­options form and the ip-network-region form.
Configuration for the system-parameters ip-options form
Set the RTCP MONITOR SERVER, Default Server IP Address to the address of the Windows 2000 PC running the VoIP Monitoring Manager Server.

Make one port available

The VMM client and server communicate using Java Remote Method Invocation (RMI), and uses the port 1099 on the machine on which the VMM server is running.
If this port is not available, the VMM server will attempt to use the following ports: 49177, 51173, or 63006. Although it is unlikely that all of these ports will be in use on a single machine, please ensure that at least one of these ports is available.

Check Windows SNMP Agent is Installed and Running

The Windows SNMP Agent must be installed before you install the VoIP Monitoring Manager Server. If Windows SNMP Agent is not installed already, you are prompted during the VoIP Monitoring Manager installation to install it from the Windows CD.
NOTE: If the Windows SNMP Agent is not installed or is not running, you will experience problems receiving data.
7
Page 16
Avaya VoIP Monitoring Manager Reference
Check if Windows SNMP Agent is Installed and Running
1. Select Start > Settings > Control Panel > Administrative Tools > Services.
2. Scroll down until you see SNMP Service. It should have a status as Started and Startup Type as Automatic. If it is not included in the list, you will need to install it from the Windows CD.
3. If the SNMP Service is listed but not set to run automatically, you will need to change its properties as follows:
1. Right-click on SNMP and select Properties from the context menu. The SNMP Service Properties dialog box opens.
2. Select Automatic from the Startup Type drop down list.
3. Click OK.

Check for a Valid SNMP Community ID

The Community ID for your Windows SNMP Agent must match the Community ID defined in the VoIP Monitoring Manager Options dialog box. By default it is public, but it may have been changed.
You cannot complete this procedure unless you have already checked that Windows SNMP is installed and running.
To Check for a Valid Community ID
1. Click Start > Settings > Control Panel > Administrative Tools > Services.
2. Scroll down and select the SNMP Service.
3. Right-click on SNMP Service, and select Properties from the context menu.
4. Select the Security tab. The VoIP Monitoring Manager Options must have a Community ID from the list of Community Names.
8
Page 17
Avaya VoIP Monitoring Manager Reference
5. Add a public ID with Read and Write privileges (if one does not already exist or is not available) for use by VoIP Monitoring Manager.
6. Click OK.

Configure SNMP Service For Sending Traps

To send traps, you need to configure the SNMP Service.
To Configure Windows SNMP Agent for Sending Traps
1. Click Start > Settings > Control Panel > Administrative Tools > Services.
2. Scroll down and select the SNMP Service.
3. Right-click on SNMP Service, and select Properties from the context menu.
4. Select the Traps tab.
5. Type the community name that is configured on the network management system to which trap messages will be sent, and click Add to list.
6. In the Trap destinations area, click Add. The SNMP Service Configuration dialog box displays.
7. In the SNMP Service Configuration dialog box, type the IP address of the network management system to which the traps will be sent, and click Add.
8. From the SNMP Service Properties dialog box, click OK.
9
Page 18
Avaya VoIP Monitoring Manager Reference
If the changes do not take effect immediately, you may have to restart the SNMP Service. To restart either service, right-click on it, and select Restart from the context menu.

Connect to Database

When VoIP Monitoring Manager is first installed, you need to connect it to the database. You also need to perform this task if you decide to change to a different database (for example, you upgrade to an SQL Server database from the standard MSDE database). This is explained in Migrate Data.
This setting is for both reading of monitor data and writing of RTCP data.
To connect to a database:
1. From the VoIP Monitoring Manager server interface, select File > Connect to Database.
2. Enter the Database Server name, Logon Name, and Password.
The database server name can be either a name or an IP address. In either case, it must be accessible on your network.
3. Click OK.

Manage your licenses

You must log into the WebLM server that manages your Avaya licenses. The license server is required to activate VoIP Monitoring Manager beyond the 90-trial period. If you do not have a license to use VoIP Monitoring Manager, you can use the software for a 90-day trial period.
10
Page 19
Avaya VoIP Monitoring Manager Reference

Customized Setup

You only need to use these procedures if you are changing the default installation (for example, creating your own database).

Change Monitoring Manager Server

To change the VoIP Monitoring Manager Server that the VoIP Monitoring Manager Client is
communicating with:
1. Select File > Connect to New Server. The Host Name of Server dialog box appears.
2. Enter the name of the new VoIP Monitoring Manager Server, and click OK.
If you are using the VoIP Monitoring Manager Client from a browser, you will be unable to change the server from which the Client is receiving information. The monitor that is displaying the Client must be directly connected to the Server that is running the VoIP Monitoring Manager Server.

Configure Database Tables

You do not need to configure the database tables as part of a normal installationthis happens automatically. You only need to configure the database tables if you initially use the default MSDE database, but then decide to migrate to an SQL Server database.

Migrate Data

Use this procedure if you want to migrate VoIP Monitoring Manager data from the standard MSDE database to an SQL Server 2000 database or an SQL Server 2005 database. Reasons for performing this migration include:
Database content needs to exceed 2 GB.  You want access to improved management and reporting tools available in SQL Server.  You want the remote administration capabilities of SQL Server.  You regularly need a connection pool of more than five connections.
11
Page 20
Avaya VoIP Monitoring Manager Reference
To migrate data:
1. Install SQL Server. VoIP Monitoring Manager supports SQL Server 2000 and SQL Server
2005.
2. Set up the VMM database:
1. Copy SetupNewVmmDatabase.zip to the MS SQL Server machine. (This zip can be found in the VMM installation\SQL folder.)
2. Extract the zip file and follow the instructions in the extracted readme.txt file.
3. Create a backup of the existing MSDE database.
4. Using the standard SQL Server tools, restore the backed-up database as a new SQL Server database. (Alternatively, use the script provided: <VMM installation directory>\sql\RestoreVmmDatabase.bat.)
5. Start Avaya VoIP Monitoring Manager Server.
6. Select File > Connect to Database.
7. Enter the Database Server name, Logon Name, and Password. (Note the default VMM login/password created by the setup scripts is VmmUser/VmmUserPassword.)
8. Click OK.
The Avaya VoIP Monitoring Manager Server shows the progress of the connection. When both Server Status and SNMP Agent Status bars at 100%, the connection has been successful.
For security reasons, you must change the VmmUser password. Run the batch file ChangeVmmUserPassword.bat, which is included in the zip, to change the password associated with the VmmUser SQL login. Then, reconfigure the VMM Server with the new password.

Overview of VoIP Monitoring Manager Client

VoIP Monitoring Manager Client

The following image displays an example of the VoIP Monitoring Manager Client in use. A search has been completed and a Summary Report is displaying ready for analysis. To familiarize yourself with the environment such as its tools and menus, click on it in the image below.

System Pane

The System pane is populated based on the media gateways that have reported to the VMM server in the last hour (or specified time period).
Data for the System pane is only obtained over the last hour because this uses an expensive query if the database is large. If your system has a small database, you may want to increase this "look back" time. To increase the "look back" time, you must change the value of the SystemViewSearchInterval attribute in the VoIPMonMgrClient.ini file. The VoIPMonMgrClient.ini file is located in the VMM installation directory. Note that the value of the SystemViewSearchInterval attribute is in hours.

Search for a Specific Network Address

You can specify in your search to display endpoints that match an IP Address or hostname by entering the address or hostname in the Advanced Search options. This is useful for narrowing
your search to a limited number of results displaying in the Results List.
You can enter:
A range of IP addresses such as 123.4.122.122 – 123.4.122.225.  A list of addresses that are separated by commas such as 123.4.102.120,
223.4.122.122, belibot.mycomputer.com.
A part of the IP address, you can use an asterisk (*) as a substitution. For example; if you
enter 123.*.*.225, it will find all addresses that start with 123 and end with 225 such as
123.4.122.225 and 123.4.190.225.
A part of the name such as belibot for belibot.mycomputer.com. However, in this situation
the search will only find hostnames in the same domain.

Search for a Specific Phone Number

You can specify in your search to display endpoints that match a specific phone number by entering in the phone number in the Advanced Search options. This is useful for narrowing your
search to a limited number of results displaying in the Results List.
You can:
Enter commas to separate numbers e.g. 9835, 9872. If you include spaces between
numbers, VoIP Monitoring Manager will remove them. So, if you enter 9835, 9822 9872, VoIP Monitoring Manager will remove the space between 9822 and 9872 and then search for 9835 and 98229872.
Use dashes to specify a range of phone numbers e.g. 2000 – 8000.  Enter a question mark (?) or asterisk (*) as a wild card. It is useful for substituting
numbers in your search. The question mark can be used multiple times. However, each ? substitutes for exactly one character. An asterisk (*) substitutes for 0 or more characters. Wild cards cannot be used in ranges.
Example Wild Card Searches
?345 = Finds all extensions that are four digits long and end with 345. (? substitutes for
exactly one character.)
9??? = Finds all the extensions from 9000 – 9999.  9* = Finds all the extensions that start with 9.

Search for a Specific SIP Username

You can specify in your search to display endpoints that match a specific SIP username by entering the SIP username in the Advanced Search options. This is useful for narrowing your
search to a limited number of results displaying in the Results List.
You can:
Enter a question mark (?) or asterisk (*) as a wild card. It is useful for substituting
characters in your search. The question mark can be used multiple times. However, each ? substitutes for exactly one character. An asterisk (*) substitutes for 0 or more characters. Wild cards cannot be used in ranges.
Example Wild Card Search
B??? = Finds all the SIP usernames that consist of four characters and begin with the
letter B.
B* = Finds all the SIP usernames that start with the letter B.

Configure Friendly Names for Gateways

By default, VMM provides an IP address (when available) for each gateway. To make it easier to identify gateways, you can assign an alias (a "friendly" name) for each gateway. When assigned, the alias for a gateway will be displayed in the Label column on the System pane. However, on the Endpoints pane, you can use the Toggle Aliases check box to view or hide the aliases.
You can assign aliases on
a per-server basis
If you configure aliases on a per-server basis, the aliases will be displayed on all VMM clients that access that VMM server.
a per-client basis
If you configure aliases on a per-client basis, each VMM client will use its own aliases for the gateways. Even though each VMM client will view the same gateways, each VMM client will have its own alias for each gateway.
both a per-server basis and a per-client basis
If you configure aliases on both a per-server basis and a per-client basis, the VMM client will use the alias from the VMM server if that VMM client does not have an alias specified for the gateway. If both the VMM server and the VMM client have specified an alias for
28
Page 37
Avaya VoIP Monitoring Manager Reference
the same gateway, VMM client will use its alias. In this configuration, the alias specified in the VMM client will always take precedence over the alias specified in the VMM server.
You can configure aliases for gateways in one of the following ways:
from the VMM Server interface  from the VMM client  via a configuration file
Configuring Aliases from the VMM Server Interface
From the VMM Server interface, you can:
add aliases  change aliases  delete aliases
To configure aliases for gateways, perform the following steps:
1. From the Edit menu, select Configure Aliases. The Alias Configuration dialog box appears.
2. Make your changes for each gateway.
3. When finished, click OK.
Configuring Aliases from the VMM Client
From the VMM client, you can:
add aliases  change aliases  delete aliases
To configure aliases for gateways, perform the following steps:
1. From the Edit menu, select Configure Aliases. The Alias Configuration dialog box appears.
2. Make your changes for each gateway.
3. When finished, click OK.
Configuring Aliases via a Configuration File
To configure aliases for gateways, you must create a gateway alias configuration file and assign an alias to the IP address of each gateway you want. In the configuration file, you define an alias for a gateway by entering the IP address of the gateway, followed by the alias you want to use. Be sure to enter one IP address and alias per line in this file.
For example, suppose you have gateways at IP addresses 192.168.33.50, 192.168.37.89, and
192.168.56.22, and you want to assign an alias to each gateway. In the gateway alias configuration file, you would enter the following information:
192.168.33.50 Bob
192.168.37.89 Alice
192.168.56.22 Jane
Once you create and save the gateway alias configuration file, you must specify the name of this file as the value of the FriendlyPath attribute in the server and/or client initialization files. By default, in both the VMM server initialization file and the VMM client initialization file, the
29
Page 38
Avaya VoIP Monitoring Manager Reference
FriendlyPath attribute is set to FriendlyLabelsServer.ini (FriendlyPath=FriendlyLabelsServer.ini).
VMM server uses the initialization file VoIPMonMgrServer.ini. VMM client uses the initialization file VoIPMonMgrClient.ini. These initialization files are located in the VMM installation directory.
NOTE: The gateway alias configuration file must be located in the same folder as the VMM initialization file (that is, VoIPMonMgrServer.ini or VoIPMonMgrClient.ini).

About Dialog

This dialog box shows
the version of VMM  the current license state (that is, whether you are using a valid license or you are running
VMM in evaluation mode)
the number of licenses purchased  the number of phones at the local server. This number represents the phones that
reported to VMM in the last 28 days. This number will increase if you move phones (for example, change extensions or IP addresses). In this case, these phones appear to be new endpoints to VMM. Since there is a 30-day grace period, this will not be a problem.
the number of phones at the local server that exceed the license (that is, the number of
phones that are unlicensed). If greater than zero, this number is displayed in red. This can occur if you have only one monitor connected to the WebLM License Server, and you have more phones stored in the database than licenses purchased.
the number of media gateways at the local server. This number represents the media
gateways that reported to VMM in the last 28 days.
the number of media gateways at the local server that exceed the license (that is, the
number of media gateways that are unlicensed). If greater than zero, this number is displayed in red. This can occur if you have only one monitor connected to the WebLM License Server, and you have more media gateways stored in the database than licenses purchased.
Avaya provides a 90-day trial version of VoIP Monitoring Manager. After 90 days, VoIP Monitoring Manager stops collecting RTCP data. You have the option of purchasing the VoIP Monitoring Manager license key. This key is required to fully activate the VoIP Monitoring Manager beyond the 90-day trial period. When a license key is purchased, an instance of WebLM License Server is required to manage the license key. If you do not have a license to use VoIP Monitoring Manager, you can use the software for a 90-day trial period.

Working with Reports (Client)

About Summary Reports

The Summary Report displays the QoS data as a reading on a gauge. The green segment of the gauge indicates values that reflect acceptable voice quality measured. The amber segment warns you of degraded voice quality levels and the red segment indicates unacceptable voice quality levels measured. The needle on the gauge shows the average values measured and the black inner arc shows the range of values measured. To edit the default range displayed on the gauges, use the Report Properties dialog.
Summary Report Features
Displays information such as the type of endpoint and the phone number.  Displays start and end dates at the bottom of the report. These dates can be altered to
narrow or lengthen the date range. This will cause the data to show more or less detail in the report.
The following is an example of a Summary Report for endpoints:

Difference Between Endpoint and Session Reports

The QoS data that displays on an endpoint report is an aggregation of all the sessions that are active at this endpoint.
Single Endpoint Reports Show Multiple Sessions
Some endpoints (such as media gateways) can participate in multiple concurrent sessions, so a high value on a single endpoint report indicates that one or more of the sessions is/was experiencing degradation of quality. It does not indicate which session.
Session Reports Display Endpoints for Only that Session
In contrast, a report showing both endpoints involved in the session displays the QoS data as experienced by both endpoints for that session only. To isolate problems, you need to narrow your search by either searching for a specific QoS value or altering the date of the report.

Summary Session Report

Summary Reports show the QoS data as a reading on a gauge. The needle on the gauge shows the average values measured and the black inner arc shows the minimum and maximum values measured.
Summary Reports for Endpoints
In a Summary Report for endpoints, the parent endpoint involved in the session displays in the top report with the child endpoint below. Each of the three QoS parameters is displayed on a separate gauge. The following is an example of a Summary Report for an endpoint:
35

Detailed Reports for Endpoints

Detailed Reports show how the QoS values change during the call and when these changes occurred. This information is displayed on a line graph for each QoS parameter. The X-axis shows the time range, and the Y-axis shows the value of the QoS parameter. Each point on the line graph represents the maximum value since the last point displayed.
Detailed Reports provide a tool tip that enables you to point your mouse at the data on the line graph to see the exact data measured. You can also alter the date range to show more or less detail.
You interpret the Detailed Report by noting where the sampled points for each QoS value appear on the line graph and when this may have occurred. The default upper values on the Y­axis indicate unacceptable limits. Select Edit>Report Properties to change the lower and upper limits of each QoS value.
To view a Detailed Report for an endpoint, click the Detailed Report tab located at the top of the report dialog box.

Interpreting Reports

Interpreting the Values Using Detailed Reports
You interpret the Detailed Reports by noting where the sampled QoS data displays on the line graph and noting when this may have occurred. The upper values on the Y-Axis indicate unacceptable limits. The X-Axis shows the date.
Table of Values for Detailed Reports
Jitter (ms) Round Trip Time (ms) Loss (%)
> 150ms Not Acceptable
50 to 150ms Warning
Crackling, static or intermittent delay could be reported.
0 to 50ms Acceptable
Conversation was smooth.

Interpreting the Values Using Summary Reports

You interpret the Summary Reports by noting where the needle on the gauges is positioned for each of the QoS gauges. When the needle is positioned in either the yellow or red ranges, it is indicating degradation in the QoS. The needle on the gauge shows the average values measured and the black inner arc shows the range of values measured. These values also display below each gauge.
> 500ms Not Acceptable
150 to 500ms Warning
Slight pause in the conversation at the lower end of the range to more lengthy delays at the top end of the range could be reported.
0 to 180ms Acceptable
No delay between each endpoint.
> 30% Not Acceptable
10 to 30% Warning
Drop out and missing parts of the conversation could be reported.
0 to 10% Acceptable
No drop out in conversation.

Y-axis
The Y-axis on the Detailed Reports line graphs is the vertical area of the report, covering the top to the bottom of the graph. The top of the Y-axis represents the upper levels for each of the QoS parameters and the bottom of the Y-axis represents the lower levels. You can point your mouse at the samples on the line graph and the exact time and QoS value will display. For more detailed information, see the topic on About Detailed Reports and/or Interpreting Detailed Reports.
No delay between each endpoint.
Warning
Slight pause in the conversation at the lower end of the range to more lengthy delays at the top end of the range could be reported.
No drop out in conversation.
Warning
Drop out and missing parts of the conversation could be reported.
Different Scales for Each QoS Parameter
The QoS parameters have different values. To represent each parameter on the same report, the Y-axis has a different scale that suits each QoS parameter. These scales are shown on the Y­axis in their respective colors.
X-axis
The X-axis on the Detailed Reports represents the date range. It is the horizontal area of the line graph, from the left to the right of the report. The start of the date range begins from the left of the horizontal axis and continues until the end of the date range on the far right side.
Alter the Date Range to Show More Detail
You can alter the date range to a shorter date or longer date period to see more or less detail.
Gateway
The Results List will display one or more phone numbers next to the Gateway endpoint type. These phone numbers are the phone numbers for which that the Gateway is acting as an intermediary. Therefore, the phone number of the Gateway can change and can be multiple
phone numbers. The Results List will separate endpoints involved in a session with a comma (,). Conferenced calls are separated by a colon (:).
48
Page 57
Avaya VoIP Monitoring Manager Reference
For example, if the following phone number 8616,1111:1222, 8904 displays in the Results List, then the Gateway has three active sessions as explained:
Telephone 8616 is a non-IP telephone that is in a session with a Softphone.  Telephones 1111 and 1222 are conferenced (for example, IP phone 8888 is in a session
with these two phones).
Telephone 8904 is a non-IP telephone in a session with an IP telephone.

About RTCP Monitor

The RTCP monitor collects the RTCP packets sent from the Avaya endpoints and stores the information in a proprietary database. The RTCP monitor also runs as a sub-agent of the Windows SNMP agent. All the information contained in the database can be queried through SQL.
The specifications for querying the database are found in:
The RTP MIB. The reference is located at http://www.ietf.org/rfc/rfc2959.txt  The proprietary AVAYA-VMON-MIB (The ASN.1 definitions of this MIB and associated
traps are included as text files in the installation)
56
Page 65
Avaya VoIP Monitoring Manager Reference

Components of RTT

RTT can comprise the following four components:
Propagation delay: The time it takes for a packet to travel across the network from
sender to receiver. This variable is based on the speed of light and the distance the signal must travel. For example, the propagation delay between Singapore and Boston is much longer than the propagation delay between New York and Boston.
Transport delay: The time it takes to traverse the network devices along a transmission
path. Networks containing many routers, firewalls, congestion and low-speed WAN services, for example, introduce more delay than an overprovisioned LAN on a single floor of a building.
Packetization delay: The time it takes for a compressor/decompressor (codec) to
digitize an analog signal, build frames and then reverse the process at the other end. The G.729 codec has a higher packetization delay than the G.711 codec.
Jitter buffer delay: The delay introduced by the receiver while it holds one or more
packets to reduce variations in packet arrival times.

Activity Monitor

Provides the ability to monitor RTCP activity for a set number of minutes, hours, or days. A trap is generated when no activity is received within the specified time period. The number must be from 1 through 99.
The check box is cleared with a setting of 4 hours, as a default setting.

About the Database

By default, all data sent to VoIP Monitoring Manager via RTCP from the endpoints is stored in the database. You can run reports against this data or export it for use in other programs, such as spreadsheets. Depending on the number of monitored terminals and the trap settings, the repository of data can become substantial.
VoIP Monitoring Manager is supplied by default with an MSDE database, which has a maximum
size of 2 GB per database. You can migrate to an SQL Server 2000 database or an SQL Server 2005 database.
If you are using an MSDE database, the historical data is stored for 30 days in the database. After 30 days, the data will be deleted.
If you are using an SQL Server 2000 database or an SQL Server 2005 database, the historical data is stored for 100 days in the database. After 100 days, the data will be deleted.
If you need access to historical data, you must either backup the database or export reports that include the required data.

Data Storage Limits and Management

If you are using an MSDE database, the historical data is stored for 30 days in the database. After 30 days, the data will be deleted.
If you are using an SQL Server 2000 database or an SQL Server 2005 database, the historical data is stored for 100 days in the database. After 100 days, the data will be deleted.

Storage Options

Store data for all calls
Records information for all calls identified by Avaya VoIP Monitoring Manager.
Only store data for calls that generate traps or warnings
Records information only for calls where the QoS levels result in a trap or warning as per the traps configurations. When this option is selected, calls are not visible unless a trap has been generated for those calls. Both ends of the session are visible for the duration of the call. If no thresholds have been exceeded for a call, no information will be recorded for that call. This is the default setting in the VoIP Monitoring Manager Server.
Data can still be viewed while a call is active.

License Server Administration Dialog Box

Enables you to log into the WebLM server that manages your Avaya licenses. The license server is required to activate VoIP Monitoring Manager beyond the 90-day trial period. If you do not have a license to use VoIP Monitoring Manager, you can use the software for a 90-day trial period.
License Server
Enter the IP address of the WebLM server.
Port Number
Enter the port number. Click the OK button to connect to the license server. If you click the Cancel button, you will be able to start VMM, but you will only be able to use it for
90 days. The Status Bar area will indicate that VMM is operating in Evaluation mode and display the number of days remaining.

About Dialog

This dialog box shows
the version of VMM  the current license state (that is, whether you are using a valid license or you are running
VMM in evaluation mode)
the number of licenses purchased  the number of phones at the local server. This number represents the phones that
reported to VMM in the last 28 days. This number will increase if you move phones (for example, change extensions or IP addresses). In this case, these phones appear to be new endpoints to VMM. Since there is a 30-day grace period, this will not be a problem.
the number of phones at the local server that exceed the license (that is, the number of
phones that are unlicensed). If greater than zero, this number is displayed in red. This can occur if you have only one monitor connected to the WebLM License Server, and you have more phones stored in the database than licenses purchased.
the number of media gateways at the local server. This number represents the media
gateways that reported to VMM in the last 28 days.
the number of media gateways at the local server that exceed the license (that is, the
number of media gateways that are unlicensed). If greater than zero, this number is displayed in red. This can occur if you have only one monitor connected to the WebLM License Server, and you have more media gateways stored in the database than licenses purchased.
Avaya provides a 90-day trial version of VoIP Monitoring Manager. After 90 days, VoIP Monitoring Manager stops collecting RTCP data. You have the option of purchasing the VoIP Monitoring Manager license key. This key is required to fully activate the VoIP Monitoring Manager beyond the 90-day trial period. When a license key is purchased, an instance of WebLM License Server is required to manage the license key. If you do not have a license to use VoIP Monitoring Manager, you can use the software for a 90-day trial period.

Getting Started with VoIP Monitoring Manager (Server)

Starting VoIP Monitoring Manager Client

You need to ensure that the VoIP Monitoring Manager (VMM) Server is installed and running on the network before you start the VMM Client. If you only have the VMM Server installed, you can also start the VMM Client as a Web Client.
To start VoIP Monitoring Manager Client:
From the PC where the VoIP Monitoring Manager Client software is installed, select Start > Programs > Avaya > VoIP Monitoring Manager > Client.
The Avaya VoIP Monitoring Manager Client window appears. Now you can search for endpoints and then view the QoS data in a report format.

Starting VoIP Monitoring Manager Web Client

The Avaya VoIP Monitoring Manager Client can run as a Web application in a browser. This is useful if you only have the server installed. To run the Avaya VoIP Monitoring Manager Client as a Web application, the following requirements must be met:
The PC on which the Avaya VoIP Monitoring Manager Server software is installed must
be running a Web server. The Apache Web server is automatically installed on the server when the Avaya VoIP Monitoring Manager Server software is installed.
The Web server must be configured to publish the file to the following VoIP Monitoring
Manager installation path: C:\Program Files\Avaya\VoIP Monitoring Manager\jars\ClientApplet.htm
The PC you will use to access the Avaya VoIP Montoring Manager Server must be able
to connect to the VMM server via a Web browser and have the following software installed:
Microsoft Internet Explorer 6 or later  SUN Java 2 Runtime Environment, SE v1.4.2_06
For more information see the topic About the VoIP Monitoring Manager Web Client
To Start Web Client
From your browser, type in the following url:
Http://VMMServerMachineName/VoIPMonMgr/ClientApplet.html
where VMMServerMachineName = the machine running the VMM Server. This url points to the machine running the VMM Server.
If you do not have the Sun Java Plug-in installed, you are prompted to install it.
60
Page 69
To exit the Web Client, just close the browser.
There are limitations in using the VMM Web Client. These are imposed by the security restrictions associated with running unsigned applets. The limitations are:
You can only access one monitor that is directly connected to the
server running the VMM Server.
You cannot:
Connect to a new server.  Use the Copy functionality.  Persist the settings from the Report Properties dialog box.  Log to the Windows event log or files.  Configure aliases for gateways on the client system.
Avaya VoIP Monitoring Manager Reference

Monitoring Server Status

When you start the VoIP Monitoring Manager Server, you will see the Server status bar and
Windows SNMP Agent status bar. When the Server is running, you will see the Server Status
bar completely filled in. When the Windows SNMP Agent is connected you will also see the SNMP Agent Status bar completely filled in.
From the VoIP Monitoring Manager Server you can:
Connect to RTCP Monitor Edit VoIP Monitoring Manager Options  Generate Traps  Configure friendly names for gateways
61
Page 70
Avaya VoIP Monitoring Manager Reference

Connect to RTCP Monitor

The Connect to RTCP Monitor enables you to re-establish the SNMP connection to the RTCP Monitor. When the VMM Server starts, it automatically attempts to establish a connection with the RTCP monitor. If the SNMP connection is lost at any time, select the Connect to RTCP Monitor option to try to manually re-establish the connection.

Changing the RTCP Listen Port

The RTCP Listen Port is the configurable port that is used to collect data from the Avaya endpoints. The number must be from 1 through 65535. The default port is 5005.
Changing the RTCP port will result in a warning that the RTCP port must match the port configured on the Avaya voice system. For more information see http://www.iana.org/assignments/port-numbers and your Avaya Call Processing or Switch Administration Forms (SAT).
You will also need to enter a Windows SNMP Agent Community ID with write access. (The default is private). It is very unusual to change the listen port since the default of 5005 should work in most situations.

Connecting to the License Server

The Connect to License Server option in the File menu enables you to log into the WebLM server that manages your Avaya licenses. If the license server was not configured during installation, you are prompted to connect to the license server the first time you start the VMM Server.
To connect to the license server:
1. From the File menu, select Connect to License Server. The License Server Administration dialog box appears.
2. In the License Server box, enter the IP address of the WebLM server.
3. In the Port Number box, enter the port number.
4. Click the OK button.
If you click the Cancel button, you will be able to start VMM, but you will only be able to use it for 90 days. The Server Status area will indicate that VMM is operating in Evaluation mode and display the number of days remaining.

Generating Traps & Alarms (Server)

Generating Traps and Alarms

You can set rules to generate traps that notify you when the VoIP network QoS parameters have reached unacceptable levels. You define the rules in the Trap Threshold Settings dialog box, which provides a tab for call traps and a tab for system and terminal traps. To open the Trap Threshold Settings dialog box, select Edit > Trap Settings from the VoIP Monitoring Manager Server interface.
You can set more than one rule for each type of trap, and each rule can be made up of more than one condition. When a rule has more than one condition, they must all be satisfied before a trap is sent (that is, they have a logical AND relationship).
The RTCP Monitor generates a trap to a pre-configured Trap Manager when the RTCP Monitor experiences the conditions defined. The Trap Manager is generally configured to be the Gateway Alarm Manager (GAM) or Network Alarm Manager (NAM), but any Trap Manager application can be used. Traps can be set for calls (sessions), systems (networks), and terminals (endpoints).
VoIP Monitor Manager creates traps based on two sets of rules:
Call Traps. If a specified condition occurs anywhere in the system, a trap is sent
immediately.
System Traps. The specified condition must occur a specified number of times before a
trap is sent. This is based on an accumulation of warnings from the entire system.

Recommended Trap Settings

Values that you use to trigger alarms must be fine-tuned to suit your environment. Appropriate settings may vary greatly from one country to another.
The default settings that are in place when VoIP Monitoring Manager is installed are a useful starting point. These settings are based on an environment with high-quality telecommunications facilities. For example, it is reasonable to expect RTT of less than 300.
Severity Jitter Delay % loss
MAJ 60 0 0
MAJ 0 500 0
MAJ 0 0 50
WRN 45 0 0
WRN 0 0 4.0
System warning interval: 100 warnings, 24 hours
Terminal warning interval: 50 warnings, 24 hours
A dialog box with the recommended major alarm settings is shown in Call Traps. A dialog box with the recommended warning alarm settings is shown in System Traps.
63
Page 72
Avaya VoIP Monitoring Manager Reference

Call Traps

A Call Trap (also referred to as a Call Alarm) is where a trap has been triggered because a customers call (session) has reached one of the pre-defined QoS parameter's thresholds.
At the end of a call, the RTCP Monitor checks its trap configurations and generates an alarm to a pre-configured Trap Manager. The conditions for the trap are defined in the Trap Threshold Settings dialog box.
The system alarm can be based on any combination of jitter, delay (RTT), or packet loss.
Example
This example shows values entered into the Trap Threshold Settings dialog box. These values would result in a trap being sent at the end of the call if at any time during the call one of the following conditions exist:
jitter >=60  delay >= 500  %loss >= 50
If the conditions in any one line are reached, then the following lines are not read. This is done to ensure that the number of traps sent for a given call is not greater than one.
Click the tabs and columns in the image for more information.
64
Page 73
Avaya VoIP Monitoring Manager Reference

System Traps

A system trap (also called a system alarm) is where a trap/alarm has been triggered because the number of warnings has exceeded the defined threshold. The trap is defined in the Trap Threshold Settings dialog box.
A trap can be defined for the total number of warnings detected on the system, or the total number of warnings detected on an individual terminal. Each trap has a specified interval during which the number of warnings must be accumulated.
The RTCP Monitor periodically checks to see if the defined interval has expired. It counts the number of warnings recorded during this interval. If it has reached the defined threshold, a system alarm is generated. To generate an alarm as soon as the thresholds are reached, use an interval of zero (0).
The system alarm can be based on any combination of jitter, delay (RTT), or packet loss.
Example
This example shows values entered in the Trap Threshold Settings dialog box. These values would result in a warning being logged at the end of the call, if at any time during the call the jitter >=45, or the %loss >= 4. If the number of warnings logged in any 24-hour period exceeds 100, as defined in the Systems No# of Warnings column, a system trap is sent.
Click the tabs in the image for more information.
65
Page 74
Avaya VoIP Monitoring Manager Reference

Terminal Traps

A terminal trap (also called a terminal alarm) is where a trap has been triggered because the number of warnings for any one terminal (endpoint) has exceeded the defined threshold. The trap is defined in the Trap Threshold Settings dialog box. You can set traps for each of the QoS parameters for calls (sessions), as well as thresholds for systems (networks), and terminals (endpoint) in the Trap dialog box.
The RTCP Monitor checks to see when the defined interval expires. It counts the number of warning traps for a specific IP endpoint. A terminal trap is sent when the number exceeds the specified number in the defined interval. To generate an alarm as soon as the thresholds are reached, use an interval of zero (0).
Example
This example shows values entered into the Trap Threshold Settings dialog. These values would result in a warning being logged at the end of the call, if at any time during the call the jitter >=45, or the %loss >= 4. If the number of warnings logged in any 24-hour interval, against a single endpoint (IP Address) exceeds 50, a terminal trap is sent for that endpoint.

Troubleshooting

Troubleshooting

Use this section to look for solutions to common problems.

License Problems

If the About dialog box indicates that you have exceeded the number of licenses, the following conditions may have occurred:
You moved phones (for example, changed extensions or IP addresses). Moving phones
will increase the number of used licenses. In this case, these phones appear to be new endpoints to VMM. Since there is a 30-day grace period, and the endpoint count consists of the last 28 days, this will not be a problem.
You need to purchase additional VMM licenses. Contact your authorized Avaya Sales
Representative.
Each VMM RTCP monitor periodically checks the number of endpoints it knows about and requests/renews the licenses for them. If there is more than one RTCP monitor and the total number of endpoints known exceeds the number of licenses, the RTCP monitor that requests licenses first will get its licenses. The RTCP monitor that requests licenses last will be denied licenses. If you enter the 30-day grace period because license limits were exceeded, the About dialog box will appear every time the VMM Server and VMM Client are started. If you exceed the 30-day grace period, VoIP Monitoring Manager stops collecting RTCP data.

If you receive the following error message you will need to change the java.policy file using the policy tool provided by SUN. The java.policy file is located in the directory where you installed Avaya VoIP Monitoring Manager. Experienced Administrators should only make changes to this file.
This VoIP Monitoring Manager Client is not permitted to access hostname. Please update the java.policy file to give this client the necessary permission you will need to restart the client or select another host.

Graph Limit Reached

If you receive the following error message, the number of reports opened has reached the VoIP
Monitoring Managers limit. Only ten reports can be displayed at once. You will need to close
some reports.
The reports for the selected endpoints could not be displayed, as the limit on the number of reports displayed would be exceeded. Please close some reports, or select fewer endpoints and try again.

Help Could Not Be Displayed

If you receive the following error message, there are problems displaying the help. You may need to check if the VoIP Monitoring Manager is installed correctly.
67
Page 76
Avaya VoIP Monitoring Manager Reference
The help could not be displayed. Please check that the VoIP Monitoring Manager is installed correctly.

Invalid Bounds

If you receive any of the following error messages then the values entered in the Report
Properties dialog box is not a valid entry. Check that the value in the left field is less than the
value in the right field or in the case for the packet loss field, the value must not be greater than or equal to 100.
The upper/lower bound must be greater than the lower bound.
The percentage loss upper bound must be greater than the lower bound and less than or
equal to 100.

Invalid Date Range

If you receive this error message then the start date selected in the Search dialog box is after the end date. You will need to change the start date or end date in the Search dialog so that the start date is before the end date.
The date range is invalid. Please ensure the start date is before the end date and try again.

Invalid Search Parameter

The Invalid Search Parameter error message displays if you have entered an incorrectly formatted entry in one or more of the fields in the Search dialog box. Follow the suggested examples in the dialog box. For more information on correct formatting, see the following topics:
Search for a Specific Phone Number  Search for a Specify SIP Username  Search for a Specific Network Address  Search Using QoS Values

No Data is Displaying on a Report

There are many reasons why data may not display on the report.
Possible Solutions
If you are using MSDE, data older than 30 days is removed from the database.  If you are using SQL server, data older than 100 days is removed from the database.  Check the VoIP Monitoring Manager Options. You may have an incorrect Windows
SNMP Agent Community ID or RTCP Listen Port setting.

No Endpoint Data Available

If you receive the following error message, the endpoint whose report is being viewed is not currently active. Wait until the endpoint becomes active again and more data will be displayed, or close the report if you are finished viewing it.
68
Page 77
Avaya VoIP Monitoring Manager Reference
There is no data currently available for this endpoint.
Explanation This happens when calls are too short to produce reporting data, or the reporting data has been
lost. If the actual call duration is comparable to the reporting period (or shorter than the reporting
period), there may be no RTCP packets received. The endpoints normally provide a reception report, but in this situation none will be received before the call ends.
Endpoints are identified by data that they send in RTCP packets. Hence if no packet is received, at least one of the session participants cannot be identified. The report shows unknown endpoint.
Calls that do not generate one or more RTCP packets are reported as having the default duration of five seconds. The actual call may have been longer up to 10 or 15 seconds.
Even if one RTCP packet is generated during a short call, it could be lost due to other environmental factors. For example, one participant might have silence suppression enabled, with the packet sent during the suppression period.

No Endpoints Matched the Search

If you receive the following error message, it could be due to one of the situations as described:
No endpoint matched the given search.
There are no endpoints reporting to the RTCP Monitor or the chosen VoIP Monitoring
Manager Server.
The calls are active, but since no data is being sent to the RTCP Monitor, the ip-network-
region form and the system-parameters ip-options form for the Avaya Communication Manager system are not configured correctly.
There were no endpoints that matched the QoS parameters in the search.  There were no endpoints that matched the search for phone number, SIP username,
Network Address, or date range as specified in the Search dialog box.
Try Broadening the Search:
Select a different date range in the Search dialog box.  Use a more general phone number pattern.  Search for all endpoints instead of just those matching a given phone number, SIP
username, or network address.

Server Unavailable

If you receive one of the following error messages, the VoIP Monitoring Manager Server has not been started. You must start the VoIP Monitoring Manager Server and verify that the machine you have attempted to connect with is the machine running the VoIP Monitoring Manager Server. If you are using the Web Client, you must refresh your browser to reconnect to the Server.

Windows SNMP Agent Connection Error

If you receive the following error message, VoIP Monitoring Manager Server is not connected to the Windows SNMP Agent. If you were viewing a report, you will need to open another report or
run a search. You may also need to check that the Windows SNMP Agent is installed and running
on the VoIP Monitoring Manager or check that the VoIP Monitoring Manager Options has a
correct SNMP Community ID.
The server could not reconnect to the SNMP Agent. This server will not be able to retrieve data until this issue is resolved. Try doing another search to make the server try to reconnect to the SNMP Agent, or connect to another server.

Server Error Messages

Server Error Messages

This part of help lists some common Server error messages that may occur as a result of mis­configuration or incorrect usage.

Check SNMP Installation

The Simple Network Management Protocol (SNMP) Agent is the Windows SNMP service that runs on your computer. SNMP is a protocol for communications between remote network management stations and managed network elements (such as Avaya devices).
The VoIP Monitoring Manager Server needs the Windows SNMP Agent installed because it enables the RTCP Monitor to collect and publish the data. The Windows SNMP service is provided with the Windows CD but is not installed by default. You will be prompted during the VoIP Monitoring Manager install to install it from the Windows CD if Windows SNMP service is not installed already.

Could Not Resolve Host Name

If you receive the following error message, the machine running the VoIP Monitoring Manager Server is not correctly configured for TCP/IP. If your IT department cannot resolve this problem, please contact customer support.
Error starting Server [text of exception raised inserted] Server exiting.

Excessive Packet Loss

Packet Loss is the result of packets being lost in the transmission from one endpoint to another.
When packet loss occurs there could be a drop out of words or partial words in the conversation. At low levels, poor voice quality would result. At high levels, the conversation becomes unintelligible. Packet Loss can result from line congestion.

General Server Error

If you receive the following error message, you must perform one of the following steps:
Reboot the machine, and restart the VoIP Monitoring Manager Server.  Contact customer support.
Unknown error starting server. Try rebooting. Please contact customer support if this error continues. Server exiting.

Invalid RTCP Port

If you receive the following error messages then the number entered in the RTCP Listen Port field in the VoIP Monitoring Manager Options is not valid. Enter a number in the range of 1 – 65535.
Please enter a port in the range 1 to 65535.

Ports used by Server

The following ports are used:
Port Function
161 SNMP Service listens on this port
162 SNMP Trap service listens on this port.
Required on the machine running the trap collector (if you are collecting traps).
1099 RMI registry runs on this port
5005 RTCP Listen port. Endpoints send RTCP to the VMM server on this port.
If any of the IP endpoints are on the other side of a firewall from the VMM server, the firewall needs to be configured to let these packets through.

Problems Binding to Port 162

When installing the VoIP Monitoring Manager, the Windows SNMP Service and the Windows SNMP Trap Service are also installed. As the Windows SNMP Trap Service opens Port 162, it is possible that it is bound to it. The Windows SNMP Service is required by the VoIP Monitoring Manager to run the RTCP Monitor, but the Windows SNMP Trap service is not required. To prevent the Trap Service from starting automatically and therefore binding to Port 162, set the Trap Service properties to manual at startup.
72
Page 81
Avaya VoIP Monitoring Manager Reference
To Set the Trap Service Startup to Manual
1. From Windows select Start > Settings > Control Panel.
2. Double-click Administrative Tools to open it.
3. Double-click Services shortcut to open it.
4. From Services, scroll down to SNMP Trap Service to select it.
5. Right-click SNMP Trap Services, and select Properties.
6. From SNMP Trap Services Properties dialog, click Stop.
7. Select Startup drop-down arrow, and select Manual.
8. Click OK and close all open folders.

RMI Registry Error

If you receive any of the following error messages, the VoIP Monitoring Manager Server is unable to start. You must reboot the machine running the VoIP Monitoring Manager Server.
Problem with RMI Registry. Ensure that port 1099 is available. You can do this by rebooting server PC. Server exiting...
Unknown problem with RMI Registry. Try rebooting. Please contact customer support if this error continues. Server exiting

Set RTCP Port Error

If you receive the following error message, there is a problem setting the RTCP port. You need to consider checking the following as indicated on the error message:
Setting the RTCP Port failed. Please check: The SNMP community ID has write access The SNMP Agent is running The port is not in use by another application

Server Cannot Connect to SNMP

This condition is not apparent unless you view the Windows Event Viewer on the server. On a client, it will not be possible to generate reports, but no relevant information is available in the event log.
This condition is caused by incomplete or incorrect installation of the server. The following DLL files cannot be found in c:\WINNT\System32\:
Msvcp70.dll Msvcr70.dll Mfc70.dll
73
Page 82
Avaya VoIP Monitoring Manager Reference
To verify that this condition has occurred, look in the System Log section of the Windows Event Viewer for event ID 1102 with the following message:
SNMP Service is ignoring Extension Agent DLL <path and file name> because it is missing or misconfigured.
If you verify this problem, copy the required DLL files from the installation CD to the required directory.
Correct operation
If the service starts normally, the following information is displayed in Application section of the Window Event Viewer:
Informational event with ID 500: You are using RtpMib.dll version 3.1.x
(the text shown in italics in this message may vary depending on the version of VoIP Monitoring Manager that is installed.)
Event Properties with Event ID 500: The Avaya RTCP Monitor has started successfully.

SNMP Service Error

If you receive any of the following error messages, it is possible that the Windows SNMP Agent is not running, or an incorrect SNMP Community ID or an ID without read access is being used. You can restart the VoIP Monitoring Manager Server.
Could not communicate with the SNMP Agent. Please ensure the Agent is running and that the correct Community ID is being used. If further problems are encountered, try running the VoIP Monitoring Manager Server installation again.
SNMP problem encountered. This probably indicates that the SNMP Agent part of the VoIP Monitoring Manager Server installation is corrupted. Please re-run the VoIP Monitoring Manager Server installation again. The VoIP Monitoring Manager Server cannot function correctly until this is fixed. Server exiting...

Unable to establish database connection

This message is displayed when you make an unsuccessful attempt to connect VoIP Monitoring Manager server to a database. Any of the following conditions can cause this error to be displayed:
The database server name is incorrect (or the IP address is incorrect), or is not
accessible on your network.
The ID is incorrect for the database.  The password is not correct.
The full message is:
Unable to establish database connection(s) using specified credentials. Please check the database server name, user name and password.

Reference Information

Characteristics of RTCP

Error data is derived from RTCP as follows:
RTCP provides support for real-time conferencing for large groups within an Internet,
including source identification and support for media gateways (like audio and video bridges) and multicast-to-unicast translators.
RTCP provides information about Round Trip Time, Jitter, Packet Loss, and other data
useful for analyzing voice quality.
Endpoints transmitting real-time data send an RTP stream, which carries the actual data
(for example, audio and/or video). The endpoints also send a corresponding RTCP stream. For more information, see RFC 1889 located at http://www.ietf.org/rfc/rfc1889.txt.

Handling Jitter

Removing Jitter
Jitter can result from bad queuing strategies set up on network equipment. Check your equipment
manual for recommended settings. To remove jitter, the endpoints need to collect packets and hold them long enough to allow the slowest packets to arrive, allowing them to be played at even intervals in the correct sequence, which causes additional delay.
Jitter Effects
Jitter can create audible voice-quality problems if the variation is greater than 60ms. Symptoms of excessive jitter could be reported as crackling or static. A faulty microphone or other hardware problems can be reported as a similar sound problem to jitter, but they are not related. You need to rule out that this is not the cause of the problem.

Interpreting RSVP Status

The RSVP status can change during a session. For example, if the RSVP status for a single endpoint in a session has changed between significant states (such as Failed and Success),
VoIP Monitoring Manager will use the label Various to represent this situation. However, if the
status has only changed from Pending to Success, then VoIP Monitoring Manager will report Success. Also, the RSVP status can be different for each endpoint in the session. For example, RSVP may be disabled for one endpoint in the session, and enabled for the other.
The RSVP status can be: Unknown:
Disabled:
Not in Use:
Reservation Pending:
Reservation Failed:
Reservation Success:
Information about the RSVP status was not available.
The end-point has been configured to ignore RSVP signaling.
RSVP is enabled for use but there is no receiver RTP channel session active, or no attempt has been made by the sender to protect the receivers RTP channel (i.e. no Path message has been received).
This state indicates that the receiver has responded to the first Path message it has received since the call started with a Resv message, and is waiting for a ResvConf to confirm the reservation is installed.
This state indicates that the receiver has had a reservation fail or timeout, or an existing reservation was torn down prematurely.
This state shows that the receivers receiving RTP channel is protected by an installed RSVP reservation. Ideally this reservation will need to be successfully refreshed until the RTP session ends.
Various:
The RSVP status for a single endpoint in a session has changed between significant states (such as Failed and Success).
81
Page 90
Avaya VoIP Monitoring Manager Reference

Interpreting Terminal Names

The canonical name or CNAME is the unique identifier for each participant within one RTP session or set of related RTP sessions.
The format is user@host, or host if a user name is not available as on single-user systems. For both formats, host is either the fully qualified domain name or IP address of the host from which the real-time data originates.
For Avaya VoIP systems CNAMEs are of the format: IP Telephone
IP Softphone
Gateway Board
Gateway Box
ext<extension>@<IP address>
ext<extension>@<IP address>
gwp@<IP address>
gwt@<IP address>

SNMP Community ID

An authentication ID allowing read and/or write access to SNMP information. This is set as part of the VMM Server configuration. A single field is used to set both the SNMP Read Community ID and the SNMP Write Community ID.
A community ID with both read and write privileges must be available to VoIP Monitoring Manager (via the SNMP dialog box). When creating the community ID, ensure that it has both read AND write privileges.
SNMP Read Community ID
The read ID is necessary for obtaining information from the agent (for example, client queries and existing configuration settings). The read ID must match the ID defined in the Windows SNMP Service Properties dialog box.
SNMP Write Community ID
The write ID is necessary for sending information to the agent. The write ID must match the ID defined in the Windows SNMP Service Properties dialog box.

TTL Considerations

For a number of reasons, packets may not get delivered to their destination in a reasonable length of time. For example, a combination of incorrect routing tables could cause a packet to loop endlessly. A solution is to discard the packet after the packet has been forwarded a certain number of times and send a message to the originator, who decides whether to resend the packet.
The initial TTL value is set, usually by a system default, in a field of the IP packet header with a value in the range 0 to 255. The original idea of TTL was that it would specify a certain time span in seconds that, when exhausted, would cause the packet to be discarded.
Since each router is required to subtract at least one count from the TTL field, the count usually indicates the number of router hops the packet has remaining before it must be discarded. Each router that receives a packet subtracts one from the count in the TTL field. When the count reaches zero, the router detecting it discards the packet and sends an Internet Control Message Protocol (ICMP) message back to the originating host.
VoIP Monitoring Manager reports the TTL value detected by the endpoint for each RTP packet it
receives.

Glossary

#
802.1D: 802.1D is reported only if it is enabled.
802.1p: 802.1p is the IEEE endorsed Layer 2 traffic prioritization setting.
802.1Q: The 802.1Q field indicates the Virtual LAN to which this device has been assigned.
A
Acoustic Echo Cancellation: The acoustic echo cancellation metric indicates if an endpoint is
configured for full-duplex, half-duplex or acoustic echo cancellation mode. The acoustic echo cancellation metric is an enumerated type metric. The possible values are: 0 = Half­duplex, 1 = Full-duplex, 2 = AEC. There is no acoustic echo cancellation on the VoIP engines. Acoustic echo cancellation is a feature for IP phones only.
Alarm: A Trap or Alarm is a message sent by a Windows SNMP Agent to a Trap Manager,
console, or terminal to indicate the occurrence of a significant event, such as a specifically defined condition or a threshold that was reached. It is also referred to as an Alarm. The Trap Manager is typically configured to be the HP OpenView or Avaya Network Management Console but any Trap Manager application can be used with the AVAYA VoIP Monitoring Manager.
Apache: Apache HTTP server is an open-source HTTP server that is maintained by the Apache
Software Foundation. A free download is available from http://www.apache.org. Follow the links to the HTTPD (HTTP daemon, web server). Note that Apache is installed as part of the Integrated Management Windows Server.
AVAYA-VMON-MIB: The AVAYA-VMON-MIB is used for the storage of VoIP Monitoring
Manager trap configuration. (The ASN.1 definitions of this MIB and associated Traps are included as text files in the installation.)
C
Canonical Name: The canonical name or CNAME is the unique identifier for each participant
within one RTP session, or set of related RTP sessions. The format is user@host, or host if a user name is not available as on single-user systems. For both formats, host is either the fully qualified domain name or IP address of the host from which the real-time data originates. For Avaya VoIP systems CNAMEs are of the format: IP Telephone: ext<extension>@<IP address>, IP Softphone: exs<extension>@<IP address>, Gateway Board: gwp@<IP address>, Gateway Box: gwt@<IP address>.
Child Endpoint: The terms parent and child endpoints are purely for describing the way
endpoints are displayed in the Results List. A parent is like the branch in a tree view. A child is like a leaf in a tree view. The same endpoint can be shown as both a parent and a child. Click on the expanding icon positioned in the far left column of the Results List to expand the tree which displays a sub list with the child endpoints. A child endpoint represents a session between itself and its parent. This is different from a parent endpoint that just represents a physical endpoint.
CLAN: The CLAN is an IP interface (LAN interface) on an Avaya media server and provides
control signalling to IP phones, Softphones, and other media gateways.
CNAME: Refer to Canonical Name.

Codec: A Codec is an encoder/decoder. In the context of RTP, it is the type of encoding used for
the payload of the RTP packets exchanged as part of a conversation. For example, some RTP Codecs are G.723, G.711 aLaw and G.729. Session Properties shows which Codec is in use. RTP does not distinguish between different sub-types of codec (such as g729A and g729B).
D
Differentiated Services Code Point: The DiffServ Code Point (DSCP) metric represents the
value of the IP DSCP field of the incoming RTP packets. The DSCP metric is a number in the range 0-63 and is used to specify the level of service a packet should receive whilst traversing the network.
DSCP: Refer to Differentiated Services Code Point.
E
Echo Tail Length: The echo tail length metric represents the length of echo cancellation
processing determined by the distance between the gateway and the endpoint. The echo tail length metric is represented in milliseconds and can have typical value ranging from 8ms to 32ms.
Endpoint Type: The Results List displays an image representing the endpoint type in the left-
hand column as follows: IP Phone - Standalone desk phone with a dedicated Ethernet dual hub, its own screen, handset, dial pad and feature access buttons; Soft Phone ­Software only phone which is installed on any PC running the Windows operating system; Media Gateway - a network VoIP device.
EndTime: The EndTime column in the exported file displays the date and time the session
ended. This column appears in the Session Table of the exported file.
F
Framesize: Frame size is the logical units into which data is partitioned for processing. In the
case of a voice coder/decoder (codec) this is the time sliced blocks used by the codec algorithm. For example, the G.729 codec breaks the input audio signal into 10ms blocks for encoding purposes. Therefore, if the RTP packet payload is in 30ms blocks then there are 3 frames per packet. VoIP Monitoring Manager displays the framesize in the Session Properties tab of the report dialog.
G
Gatekeeper: The Gatekeeper column in the Session Table displays the media server or CLAN
that controls the endpoint.
Gateway: A Gateway is generally used as a bridge between signaling protocols and bearer
media. In this context, the Gateways allow IP endpoints to communicate with non-IP endpoints (e.g. the traditional circuit switched world of analogue and digital phones). AVAYA Gateways also perform the task of mixing the media channels in a conference call. A pair of Gateways can also be set up as an IP trunk.

H
HopAddress: The Hop Address column in the Trace Route Table is the IP address of each
network node in the trace route.
HopCount: The HopCount column in the Trace Route Table indicates the hop number, that is,
the position in the path node of the trace route.
HopTime: The HopTime column in the Trace Route Table displays in milliseconds the round-trip-
time of the trace route packet, from the source to each path node in the trace route.
I
Interval: The period during which the specified number of warnings must be received to trigger
an alarm (trap).
J
Jitter: Jitter is a measure of variance in the time it takes for communications to traverse from the
sender (application) to the receiver, as seen from the application layer, or the difference between when a packet is supposed to be received and when it is actually received. Jitter is sometimes described as the statistical average variance in delivery time between packets or datagrams. Avaya VoIP Monitoring Manager reports Jitter in milliseconds.
Jitter Buffer Over Runs: The number of jitter buffer over-runs metric represents the number of
times during a call the actual jitter exceeded the maximum size to which the jitter buffer is allowed to grow. This metric is an 8-bit unsigned integer.
Jitter Buffer Under Runs: The number of jitter buffer under-runs metric represents the number
of times during a call the jitter buffer became empty or starved. This metric is an 8-bit unsigned integer.
L
Largest Sequence Fall: The Largest Sequence Fall metric represents the number of packets
that are received later than expected, that is, after a higher-numbered packet was received. For example, if five packets arrive in the order 1, 2, 5, 3, 4, the largest sequence fall is 2 (generally indicating that 2 packets arrived later than expected). Note: A value of 0xFF implies that there were too many packets out of order to be able to calculate the correct value.
Largest Sequence Jump: The Largest Sequence Jump metric represents the maximum number
of consecutive packets lost in the last RTCP reporting interval. It is based on sequence numbers assigned to packets as they are created. For example, when the following packet sequence numbers 1,2,3,8 are received, the largest Sequence Jump is 4. Note: A value of 0xFF implies that there were too many packets lost to be able to calculate the correct value.
LargestSeqFall: Refer to Largest Sequence Fall. LargestSeqJump: Refer to Largest Sequence Jump.

M
Maximum Jitter: The Maximum Jitter metric represents the maximum value of jitter seen in the
RTCP reporting interval. This metric would be useful to identify transient spikes of jitter in a session. This metric is a 32-bit unsigned integer. The unit is defined by the profile of the RTP session.
Media Encryption: The Media Encryption metric indicates whether media encryption is enabled
or disabled for the RTP session. The Media encryption metric is an enumerated type metric. The possible values are: 0 = No encryption, 1 = AEA1.2, 2 = AES, 3-255 = Reserved for future use.
N
Number Sequence Falls: The number of sequence fall metric represents how many times during
the RTP session there was at least one packet that was out of order.
Number Sequence Jumps: The number of sequence jump instances metric represents how
many times during the reporting interval there was at least one packet which was lost.
NumberSeqFalls: Refer to Number Sequence Falls. NumberSeqJumps: Number Sequence Jumps.
O
Octet: The Octet column in the Session Table indicates the size of the packets in octets.
P
Packet: A packet is the logical grouping of information that includes a header containing control
information and (usually) the user data. The term packet is most often used to refer to the application layer data units.
Parent Endpoint: The terms parent and child endpoints are purely for describing the way
endpoints are displayed in the Results List. A parent is like the branch in a tree view. A child is like a leaf in a tree view. The same endpoint can be shown as both a parent and a child. A parent endpoint is any endpoint listed as a result of a search. You click on the expanding key icon positioned in the far left column to expand the parent endpoint and show the child endpoints.
ParticipantID: The ParticipantID column assigns a unique identifier to each participant in the
exported file. Each exported session has two participants. The exported data contains three sets of data. This data is listed in three separate tables that are separated by a blank row: Session Table, Time-varying Data Table and the TraceRoute Table. For every session a participant was involved in there will be a unique pair: SessionID and ParticipantID, enabling you to associate the session data, time-varying data and the trace route data as belonging to that participant in a specific session. Use the ParticipantID to identify the participant in each table to analyze the data.
Payload: Payload refers to the contents of a packet. In RTP it is encoded audio that is the user
data of a packet. The payload identifies which codec is being used.
Perceived Delay: Perceived delay is the total effect RTT and Jitter have on a phone user's
conversation.

Q
QoS: Refer to Quality of Service. Quality of Service: QoS is the measure of the level of quality that a service requires or receives.
The VoIP Monitoring Manager monitors and displays the 3 main factors that determine the quality of VoIP calls. These factors are Jitter, Round Trip Time, and Packet Loss. On the Summary Report each of the three factors display as a separate gauge.
R
RcvrIPAddr: The RcvrIPAddr column displays the IP address of this session participant (i.e.
endpoint). This column appears in the Session Table of the exported file.
RcvrPHONE: The RcvrIPAddr column displays the phone number of the participant. This column
appears in the Session Table of the exported file.
Real-Time Transport Control Protocol: A protocol providing support for applications with real-
time properties, including timing reconstruction, loss detection, security, and content identification. It reports information about the RTP stream.
Real-Time Transport Protocol: Real-Time Transport Protocol is the protocol used for
transmitting real-time data. For more information see IETF RFC 1889 located at: http://www.ietf.org/rfc/rfc1889.txt
Resource ReSerVation Protocol: RSVP is a protocol for reserving network bandwidth on the
routers and switches between two endpoints in a session (in some other protocol, such as RTP). There are two reservations per session, one for each direction the data has to travel. For further reference see the IETF RFCs 2205 and 2750 located at: http://www.ietf.org/rfc/rfc2205.txt and http://www.ietf.org/rfc/rfc2750.txt
Round Trip Time: Round trip time is the length of time (in milliseconds) it takes a packet to
traverse the network and return (thus being a round trip). It is the sum of the two one-way network delays between two endpoints. Callers can experience difficulties in carrying on a normal conversation when the one-way network delay exceeds 500 milliseconds (ms). However, some users may elect to tolerate this.
RSVP: Refer to Resource ReSerVation Protocol. RSVP Status: The RSVP status for an endpoint shows whether the RSVP is enabled on the
endpoint, and if it is, whether a reservation was established for the received RTP data stream.
RTCP: Refer to Real-Time Transport Control Protocol. RTCP Listen Port: The RTCP Listen Port is the configurable port that is used to collect RTCP
information from the AVAYA endpoints. The number must be from 1025 through 65535. The default port is 5005. Users are advised to avoid choosing ports in the reserved and 'well-known' ranges.
RTP: Refer to Real-Time Transport Protocol. RTP MIB: The RTP MIB stores the information for the active RTP Sessions. The reference for the
definition of the RTP MIB is located at: http://www.ietf.org/rfc/rfc2959.txt
RTP Session: A session is a VoIP connection between two IP endpoints. For more information
see RFC 1889 located at: http://www.ietf.org/rfc/rfc1889.txt
RTT: Refer to Round Trip Time.

S
Session Table: The Session table is the exported table containing data that generally remains
the same during a session. As a result, there is one entry per session in this table. The Session table will display in Microsoft Excel at the top of the same worksheet as the Time-varying Data table and the Trace Route table. The data in the Session table is indexed by SessionID and ParticipantID.
SessionID: The SessionID column assigns a unique identifier to each session in the exported
file. Each exported session contains three sets of data. This data is listed in three separate tables that are separated by a blank row: Session Table, TimeStamped DataTable and the TraceRoute Table. Use the SessionID to identify the session in each table to analyze the data.
Silence Suppression: In Voice over IP (VoIP), silence suppression is a method of detecting the
silence in audio and purposefully dropping silent packets at the sender to conserve network bandwidth. The receiver will generate comfort noise or conceal the loss of packets when packets are dropped. Because the receiver conceals loss and generates comfort noise, silence suppression is usually imperceptible to the listener. The silence suppression will be reported as enabled, disabled or unknown.
Simple Network Management Protocol: SNMP is a standard protocol for communicating with
network devices.
SNMP: Refer to Simple Network Management Protocol. StartTime: The StartTime column in the exported file displays the date and time the session
started. This column appears in the Session Table of the exported file.
T
Time-To-Live: Time-to-live (TTL) is a value in an Internet Protocol (IP) packet that tells a
network router if a packet has been forwarded towards its destination too many times and should be discarded.
Time-varying Data Table: The Time-varying Data table is one of the exported tables containing
the time-varying data for the sessions in the Session table. The data in this table is indexed by SessionID, ParticipantID, and a time offset. The SessionID and ParticipantID enable the data to be linked to corresponding sessions in the Session table. The time offset indicates when this set of information was reported (in seconds since the start of each call). The Time-varying Data table will display in Microsoft Excel below the Session table on the same worksheet. To view the information more easily, you may want to copy the table and paste it to another worksheet.
TimeOffset: The TimeOffset column displays the number of seconds since the session started
for this set of data. This column appears in the Time-varying Data Table of the exported file.
TOOL: The TOOL value is the name and version of the application generating the stream, for
example, Avaya VoIP Engine v.123. This information may be useful for diagnosis. The TOOL value should remain constant for the duration of the session.
Trace Route Table: The Trace Route table contains information about the route in the network
that the RTP packets traverse between the two endpoints of the call. It will display in Microsoft Excel below the Time-varying Data table.
Trap: Refer to Alarm TTL: Refer to Time-To-Live.

V
Voice over Internet Protocol: Voice over Internet Protocol (VoIP) is the technology standard
that supports Internet telephony. It provides the capability for live voice communication over the Internet so that you can talk using the multimedia capabilities of your computer, in the same way you would talk using a telephone.
VoIP: Refer to Voice over Internet Protocol.
W
Windows SNMP Agent: The Windows SNMP Agent runs as an operating-system-managed
service. It is optionally installed with the Windows Operating System.
