About This Manual

This manual is about Voice-over-IP products made by Multi-Tech Systems, Inc. It describes three analog MultiVOIP units, models MVP810, MVP410, and MVP210.

These MultiVOIP units can inter-operate with other contemporary analog MultiVOIP units (MVP130 & MVP130FXS), with contemporary BRI MultiVOIP units (MVP410ST & MVP810ST), with contemporary digital T1/E1/ISDN-PRI MultiVOIP units (MVP2410 and MVP3010), and with the earlier generation of MultiVOIP products (MVP200, MVP400, MVP800, MVP120, etc.)

The table below (on next page) describes the vital characteristics of the various models described in this manual.

How to Use This Manual. In short, use the index and the examples. When our readers crack open this large manual, they generally need one of two things: information on a very specific software setting or technical parameter (about telephony or IP) or they need help when setting up phonebooks for their voip systems. The index gives quick access to voip settings and parameters. It’s detailed. Use it. The best way to learn about phonebooks is to wade through examples like those in our chapters on T1 (North American standard) Phonebooks and E1 (Euro standard) Phonebooks. Finally, this manual is meant to be comprehensive. If you notice that something important is lacking, please let us know.

Additional Resources. The MultiTech web site (www.multitech.com) offers both a list of Frequently Asked Questions (the MultiVOIP FAQ) and a collection of resolutions of issues that MultiVOIP users have encountered (these are Troubleshooting Resolutions in the searchable Knowledge Base).

MultiVOIP User Guide Overview

Introduction to TI MultiVOIPs (MVP2410 & MVP24-48)

We proudly present MultiTech’s T1 Digital Multi-VOIP products. The MVP2410 is a rack-mount model; and the MVP24-48 is an add-on expansion card that doubles the capacity of the MVP2410 without adding another chassis. These voice-over-IP products have fax capabilities. These models adhere to the North American standard of T1 trunk telephony using digital 24-channel time-division multiplexing, which allows 24 phone conversations to occur on the T1 line simultaneously. They can also accommodate T1 lines of the ISDN Primary Rate Interface type (ISDN-PRI).

Figure 1-1. MultiVOIP MVP2410 LEDs

Scale-ability. The MVP2410 is tailored to companies needing more than a few voice-over-IP lines, but not needing carrier-class equipment. When expansion is needed, the MVP2410 can be field-upgraded into a dual T1 unit by installing the MVP24-48 kit, which is essentially a second MultiVOIP motherboard that fits in an open expansion-card slot in the MVP2410. The upgraded dual unit then accommodates two T1 lines.

T1 VOIP Traffic. The MVP2410 accepts its outbound traffic from a T1 trunk that’s connected to either a PBX or to a telco/carrier. The MVP2410 transforms the telephony signals into IP packets for transmission on LANs, WANs, or the Internet. Inbound IP data traffic is converted to telephony data and signaling.

When connected to PBX. When connected to a PBX, the MVP2410 creates a network node served by 10/100-Base T connections. Local PBX phone extensions gain toll-free access to all phone stations directly connected to the VOIP network. Phone extensions at any VOIP location also gain toll-free access to the entire local public-switched telephone network (PSTN) at every other VOIP location in the system.

When connected to PSTN. When the T1 line(s) connected to the MVP2410 are connected directly to the PSTN, the unit becomes a Pointof-Presence server dedicated to local calls off-net.

Overview MultiVOIP User Guide

H.323, SIP & SPP. Being H.323 compatible, the MVP2410 can place calls to telephone equipment at remote IP network locations that also contain H.323 compatible voice-over-IP gateways. It will interface with H.323 software and H.323 gatekeeper units. H.323 specifications also bring to voip telephony many special features common to conventional telephony. H.323 features of this kind that have been implemented into the MultiVOIP include Call Hold, Call Waiting, Call Name Identification, Call Forwarding (from the H.450 standard), and Call Transfer (H.450.2 from H.323 Version 2). The fourth version of the H.323 standard improves system resource usage (esp. logical port or socket usage) by handling call signaling more compactly and allowing use of the low-overhead UDP protocol instead of the error-correcting TCP protocol where possible.

The MultiVOIP is also SIP-compatible. (“SIP” means Session Initiation Protocol.) However, H.450 Supplementary Services features can be used under H.323 only and not under SIP.

SPP (Single-Port Protocol) is a non-standard protocol developed by Multi-Tech. SPP is not compatible with the “Proprietary” protocol used in Multi-Tech’s earlier generation of voip gateways. SPP offers advantages in certain situations, especially when firewalls are used and when dynamic IP address assignment is needed. However, when SPP is used, certain features of SIP and H.323 will not be available and SPP will not inter-operate with voip systems using H.323 or SIP.

Data Compression & Quality of Service. The MultiVOIP MVP2410 comes equipped with a variety of data compression capabilities, including G.723, G.729, and G.711 and features DiffServ quality-ofservice (QoS) capabilities.

VOIP Functions. The MultiVOIP MVP2410 gateway performs four basic functions: (a) it converts a dialed number into an IP address, (b) it sends voice over the data network, (c) it establishes a connection with another VOIP gateway at a remote site, and (d) it receives voice over the data network. Voice is handled as IP packets with a variety of compression options. Each T1 connection to the MultiVOIP provides 24 time-slot channels to connect to the telco or to serve phone or fax stations connected to a PBX.

Ports. The MVP2410 has one 10/100 Mbps Ethernet LAN interface and one Command port for configuration. An MVP2410 upgraded with the MVP24-48 kit will have two Ethernet LAN interfaces and two Command ports.

PSTN Failover Feature. The MultiVOIP can be programmed to divert calls to the PSTN temporarily in case the IP network fails.

MultiVOIP User Guide Overview

RADIUS Support. Inter-operation with a RADIUS server allows for call accounting (especially for billing) on a voip system. The MultiVOIP supports inter-operation with RADIUS servers for the RADIUS accounting function (but not the RADIUS authentication function).

STUN Support. The STUN protocol (Simple Traversal of UDP through NATs (Network Address Translation)) assists with the packet routing functions of devices behind NAT firewalls or routers. The MultiVOIP supports inter-operation with STUN servers and NATs (SIP based environment only).

Gatekeeper. T1 voip systems can have gatekeeper functionality by adding, as an endpoint, a Multi-Tech standalone gatekeeper (special software residing in separate hardware). Gatekeepers are optional but useful within voip systems. The gatekeeper acts as the ‘clearinghouse’ for all calls within its zone. MultiTech’s stand-alone gatekeeper software performs all of the standard gatekeepers functions (address translation, admission control, and bandwidth control) and also supports many valuable optional functions (call control signaling, call authorization, bandwidth management, and call management).

Management. Configuration and system management can be done locally with the MultiVOIP configuration software. After an IP address has been assigned locally, other configuration can be done remotely using the MultiVOIP web browser GUI. Remote system management can be done with the MultiVoipManager SNMP software or via the MultiVOIP web browser GUI. All of these control software packages are included on the Product CD.

Overview MultiVOIP User Guide

While the web GUI’s appearance differs slightly, its content and organization are essentially the same as that of the Windows GUI (except for logging).

MultiVOIP User Guide Overview

The primary advantage of the web GUI is remote access for control and configuration. The controller PC and the MultiVOIP unit itself must both be connected to the same IP network and their IP addresses must be known.

Once you’ve begun using the web browser GUI, you can go back to the MultiVOIP Windows GUI at any time. However, you must log out of the web browser GUI before using the MultiVOIP Windows GUI.

Overview MultiVOIP User Guide

Logging of System Events. MultiTech has built SysLog Server functionality into the software of the MultiVOIP units. SysLog is a de facto standard for logging events in network communication systems.

The SysLog Server resides in the MultiVOIP unit itself. To implement this functionality, you will need a SysLog client program (sometimes referred to as a “daemon”). SysLog client programs, both paid and freeware, can be obtained from Kiwi Enterprises, among other firms. See www.kiwisyslog.com

. SysLog client programs essentially give you a means of structuring console messages for convenience and ease of use.

MultiTech Systems does not endorse any particular SysLog client program. SysLog client programs by any qualified provider should suffice for use with MultiVOIP units. Kiwi’s brief description of their SysLog program indicates the typical scope of such programs. “Kiwi Syslog Daemon is a freeware Syslog Daemon for the Windows platform. It receives, logs, displays and forwards Syslog messages from hosts such as routers, switches, Unix hosts and any other syslog enabled device. There are many customizable options available.”

MultiVOIP User Guide Overview

Supplementary Telephony Services. The H.450 standard (an addition to H.323) brings to voip telephony more of the premium features found in PSTN and PBX telephony. MultiVOIP units offer five of these H.450 features: Call Transfer, Call Hold, Call Waiting, Call Name Identification (not the same as Caller ID), and Call Forwarding. (The first four features are found in the “Supplementary Services” window; the fifth, Call Forwarding, appears in the Add/Edit Inbound phonebook screen.) Note that the first three features are closely related. All of these H.450 features are supported for H.323 operation only; they are not supported for SIP or SPP.

T1 Front Panel LEDs

The MVP2410 and MVP24-48 both use a common main circuit board or motherboard. Consequently the LED indicators are the same for both.

Active LEDs. The MVP2410 front panel has two sets of identical LEDs. In the MVP2410 as shipped (that is, without an expansion card), the left-hand set of LEDs is functional whereas the right-hand set is not.

When the MVP2410 has been upgraded with an MVP24-48 kit, the right-hand set of LEDs will also become active.

Figure 1-2: MVP2410 LEDs

T1 LED Descriptions. The descriptions below apply to the digital T1 MultiVOIP units. The MVP2410 has four sets of LEDs plus a lone LED at its far right end. As viewed from the front of the MVP2410, it is the two left groups that are active and present feedback about the operation of the unit. If an MVP24-48 expansion card is added to the MVP2410, the two LED groups on the right become operational with respect to the second T1 connection.

Introduction to EI MultiVOIPs (MVP3010 & MVP30-60)

We proudly present MultiTech’s E1 Digital Multi-VOIP products. The MVP3010 is a rack-mount model and the MVP30-60 is an add-on expansion card that doubles the capacity of the MVP3010 without adding another chassis. All of these voice-over-IP products have fax capabilities. All adhere to the European standard of E1 trunk telephony using digital 30-channel time-division multiplexing, which allows 30 phone conversations to occur on the E1 line simultaneously. All can also accommodate E1 lines of the ISDN Primary Rate Interface type (ISDN-PRI).

Figure 1-3. MultiVOIP MVP3010 Chassis

Scale-ability. The MVP3010 is tailored to companies needing more than a few voice-over-IP lines, but not needing carrier-class equipment. When expansion is needed, the MVP3010 can be field-upgraded into a dual E1 unit by installing the MVP30-60 kit, which is essentially a second MultiVOIP motherboard that fits into an open expansion-card slot in the MVP3010. The upgraded dual unit then accommodates two E1 lines.

Safety Recommendations for Rack Installations

Ensure proper installation of the unit in a closed or multi-unit enclosure by following the recommended installation as defined by the enclosure manufacturer. Do not place the unit directly on top of other equipment or place other equipment directly on top of the unit. If installing the unit in a closed or multi-unit enclosure, ensure adequate airflow within the rack so that the maximum recommended ambient temperature is not exceeded. Ensure that the unit is properly connected to earth ground by verifying that it is reliably grounded when mounted within a rack. If a power strip is used, ensure that the power strip provides adequate grounding of the attached apparatus.

When mounting the equipment in the rack, make sure mechanical loading is even to avoid a hazardous condition, such as loading heavy equipment in rack unevenly. The rack used should safely support the combined weight of all the equipment it supports.

Ensure that the mains supply circuit is capable of handling the load of the equipment. See the power label on the equipment for load requirements (full specifications for MultiVOIP models are presented in chapter 1 of this manual).

Maximum ambient temperature for the unit is 60 degrees Celsius (140 degrees Fahrenheit) at 20-90% non-condensing relative humidity. This equipment should only be installed by properly qualified service personnel. Only connect like circuits. In other words, connect SELV (Secondary Extra Low Voltage) circuits to SELV circuits and TN (Telecommunications Network) circuits to TN circuits.

19-Inch Rack Enclosure Mounting Procedure

Attaching the MultiVOIP to a rack-rail of an EIA 19-inch rack enclosure will certainly require two persons. Essentially, the technicians must attach the brackets to the MultiVOIP chassis with the screws provided, as shown in Figure 3-3, and then secure unit to rack rails by the brackets, as shown in Figure 3-4. Because equipment racks vary, screws for rack-rail mounting are not provided. Follow the instructions of the rack manufacturer and use screws that fit.

1. Position the right rack-mounting bracket on the MultiVOIP using the two vertical mounting screw holes.

2. Secure the bracket to the MultiVOIP using the two screws provided.

3. Position the left rack-mounting bracket on the MultiVOIP using the two vertical mounting screw holes.

4. Secure the bracket to the MultiVOIP using the two screws provided.

5. Remove feet (4) from the MultiVOIP unit.

6. Mount the MultiVOIP in the rack enclosure per the rack manufacture’s mounting procedure.

Introduction

Configuring software for your MultiVOIP entails three tasks: (1) loading the software onto the PC (this is “Software Installation and is discussed in this chapter), (2) setting values for telephony and IP parameters that will fit your system (this is “Technical Configuration” and it is discussed in Chapter

5), and

(3) establishing “phonebooks” that contain the various dialing patterns for VOIP calls made to different locations (this is “Phonebook Configuration” and it is discussed in Chapter 6 for North American (T1) telephony standards and in Chapter 7 for European (E1) telephony standards.

Loading MultiVOIP Software onto the PC

The software loading procedure does not present every screen or option in the loading process. It is assumed that someone with a thorough knowledge of Windows and the software loading process is performing the installation.

The MultiVOIP software and User Guide are contained on the MultiVOIP product CD. Because the CD is auto-detectable, it will start up automatically when you insert it into your CD-ROM drive. When you have finished loading your MultiVOIP software, you can view and print the User Guide by clicking on the View Manuals icon.

1. Be sure that your MultiVOIP has been properly cabled and that the power is turned on.

Technical Configuration MultiVOIP User Guide

Configuring the MultiVOIP

There are two ways in which the MultiVOIP must be configured before operation: technical configuration and phonebook configuration.

Technical Configuration. First, the MultiVOIP must be configured to operate with technical parameter settings that will match the equipment with which it interfaces. There are eight types of technical parameters that must be set.

These technical parameters pertain to (1) its operation in an IP network, (2) its operation with telephony equipment, (3) its transmission of voice and fax messages, (4) its interaction with SNMP (Simple Network Management Protocol) network management software (MultiVoipManager), (5) certain telephony attributes that are common to particular nations or regions, (6) its operation with a mail server on the same IP network (per SMTP parameters) such that log reports about VoIP telephone call traffic can be sent to the administrator by email, (7) implementing some common premium telephony features (Call Transfer, Call Hold, Call Waiting, Call ID – “Supplementary Services”), and (8) selecting the method by which log reports will be made accessible.

The process of specifying values for the various parameters in these seven categories is what we call “technical configuration” and it is described in this chapter.

Phonebook Configuration. The second type of configuration that is required for the MultiVOIP pertains to the phone number dialing sequences that it will receive and transmit when handling calls. Dialing patterns will be affected by both the PBX/telephony equipment and the other VOIP devices that the MultiVOIP unit interacts with. We call this “Phonebook Configuration,” and, for analog MultiVOIP units, it is described in Chapter 6. The Quick Start Guide presents additional information on phonebook setup.

Local/Remote Configuration. The MultiVOIP must be configured locally at first (to establish an IP address for the MultiVOIP unit). But changes to this initial configuration can be done either locally or remotely.

MultiVOIP User Guide Technical Configuration

Local configuration is done through a connection between the “Command” port of the MultiVOIP and the COM port of the computer; the MultiVOIP configuration program is used.

Remote configuration is done through a connection between the MultiVOIP’s Ethernet (network) port and a computer connected to the same network. The computer could be miles or continents away from the MultiVOIP itself. There are two ways of doing remote configuration and operation of the MultiVOIP unit: (1) using the MultiVoipManager SNMP program, or (2) using the MultiVOIP web browser interface program.

MultiVoipManager. MultiVoipManager is an SNMP agent program (Simple Network Management Protocol) that extends the capabilities of the MultiVOIP configuration program: MultiVoipManager allows the user to manage any number of VOIPs on a network, whereas the MultiVOIP configuration program can manage only the VOIP to which it is directly/locally connected. The MultiVoipManager can configure multiple VOIPs simultaneously, whereas the MultiVOIP configuration program can configure only one at a time.

MultiVoipManager may (but does not need to) reside on the same PC as the MultiVOIP configuration program. The MultiVoipManager program is on the MultiVOIP Product CD. Updates, when applicable, may be posted at on the MultiTech FTP site. To download, go to

ftp://ftp.multitech.com/MultiVoip/

Web Browser Interface. The MultiVOIP web browser GUI gives access to the same commands and configuration parameters as are available in the MultiVOIP Windows GUI except for logging functions. When using the web browser GUI, logging can be done by email (the SMTP option).

Technical Configuration MultiVOIP User Guide

Functional Equivalence of Interfaces. The MultiVOIP configuration program is required to do the initial configuration (that is, setting an IP address for the MultiVOIP unit) so that the VOIP unit can communicate with the MultiVoipManager program or with the web browser GUI. Management of the VOIP after that point can be done from any of these three programs since they all offer essentially the same functionality. Functionally, either the MultiVoipManager program or the web browser GUI can replace the MultiVOIP configuration program after the initial configuration is complete (with minor exceptions, as noted).

WARNING: Do not attempt to interface the MultiVOIP unit with

two control programs simultaneously (that is, by accessing the MultiVOIP configuration program via the Command Port and either the MultiVoipManager program or the web browser interface via the Ethernet Port). The results of using two programs to control a single VOIP simultaneously would be unpredictable.

MultiVOIP User Guide Technical Configuration

Local Configuration

This manual primarily describes local configuration with the Windows GUI. After IP addresses have been set locally using the Windows GUI, most aspects of configuration (logging functions are an exception) can be handled through the web browser GUI, as well (see the Operation and Maintenance chapter of this manual). In most aspects of configuration, the Windows GUI and web-browser GUI differ only graphically, not functionally. For information on SNMP remote configuration and management, see the MultiVoipManager documentation.

Pre-Requisites

To complete the configuration of the MultiVOIP unit, you must know several things about the overall system.

Before configuring your MultiVOIP Gateway unit, you must know the values for several IP and telephone parameters that describe the IP network system and telephony system (PBX or telco central office equipment) with which the digital MultiVOIP will interact. If you plan to receive log reports on phone traffic by email (SMTP), you must arrange to have an email address assigned to the VOIP unit on the email server on your IP network. A summary of this configuration information appears on page 58 (“Config Info CheckList”).

Local Configuration Procedure (Detailed)

You can begin the configuration process as a continuation of the MultiVOIP software installation. You can establish your configuration or modify it at any time by launching the MultiVOIP program from the Windows Start menu.

1. Check Power and Cabling. Be sure the MultiVOIP is turned on and connected to the computer via the MultiVOIP’s Command Port (DB9 connector at computer’s COM port; RJ45 connector at MultiVOIP).

2. Start MultiVOIP Configuration Program. Launch the MultiVOIP program from the Windows Start menu (from the folder location determined during installation).

MultiVOIP User Guide Technical Configuration

3. Confirm Connection. If the MultiVOIP is set for an available COM port and is correctly cabled to the PC, the MultiVOIP main screen will appear. (If the main screen appears grayed out and seems inaccessible, go to step 4.)

Technical Configuration MultiVOIP User Guide

In the lower left corner of the screen, the connection status of the MultiVOIP will be displayed. The messages in the lower left corner will change as detection occurs. The message “MultiVOIP Found” confirms that the MultiVOIP is in contact with the MultiVOIP configuration program. Skip to step 5.

MultiVOIP User Guide Technical Configuration

4. Solving Common Connection Problems.

A. Fixing a COM Port Problem. If the MultiVOIP main screen appears

but is grayed out and seems inaccessible, the COM port that was specified for its communication with the PC is unavailable and must be changed. An error message will appear.

To change the COM port setting, use the COM Port Setup dialog box, which is accessible via the keyboard shortcut Ctrl + G or by going to the Connection pull-down menu and choosing “Settings.” In the “Select Port” field, select a COM port that is available on the PC. (If no COM ports are currently available, re-allocate COM port resources in the computer’s MS Windows operating system to make one available.)

Ctrl + G

Routers that support DiffServ can examine the six DSCP bits and prioritize the packet based on the DSCP value. The DiffServ Parameters fields in the MultiVOIP IP Parameters screen allow you to configure the DSCP bits to values supported by the router. Specifically, the Voip Media PHB field relates to the prioritizing of audio packets (RTP and RTCP packets) and the Call Control PHB field relates to the prioritzing of non-audio packets (packets concerning call set-up and tear-down, gatekeeper registration, etc.).

The MultiVOIP Call Control PHB parameter defaults to 34 decimal (22 hex; 100010 binary – consider vis-à-vis TOS field above) for Assured Forwarding behavior. The MultiVOIP Voip Media PHB parameter defaults to the value 46 decimal (2E hex; 101110 binary – consider vis-à-vis TOS field above). To disable DiffServ, configure both fields to 0 decimal.

AutoCall/Offhook Alert

Parameters

Auto Call / Offhook Alert

AutoCall, Offhook Alert

The AutoCall option enables the local MultiVOIP to call a remote MultiVOIP without the user having to dial a Phone Directory Database number. As soon as you access the local MultiVOIP voice/fax channel, the MultiVOIP immediately connects to the remote MultiVOIP identified in the Phone Number box of this option.

If the “Pass Through Enable” field is checked in the Interface Parameters screen, AutoCall must be used.

The Offhook Alert option applies only to FXS channels.

The Offhook Alert option works like this: if a phone goes offhook and yet no number is dialed within a specific period of time (as set in the Offhook Alert Timer field), then that phone will automatically dial the Alert phone number for the voip channel. (The Alert phone number must be set in the Voice/Fax Parameters | Phone Number field; if the voip system is working without a gatekeeper unit, there must also be a matching phone number entry in the Outbound Phonebook.). One use of this feature would be for emergency use where a user goes off hook but does not dial, possibly indicating a crisis situation. The Offhook Alert feature uses the Intercept Tone, as listed in the Regional Parameters screen. This tone will be outputted on the phone that was taken off hook but that did not dial. The other end of the connection will hear audio from the “crisis” end as is it would during a normal phone call.

Field Name Values Description

Dynamic Jitter

Dynamic Jitter Buffer

Dynamic Jitter defines a minimum

and a maximum jitter value for voice communications. When receiving voice packets from a remote

MultiVOIP, varying delays

between packets may occur due to network traffic problems. This is called Jitter. To compensate, the MultiVOIP uses a Dynamic Jitter Buffer. The Jitter Buffer enables the MultiVOIP to wait for delayed voice packets by automatically adjusting the length of the Jitter Buffer between configurable minimum and maximum values. An Optimization Factor adjustment controls how quickly the length of the Jitter Buffer is increased when jitter increases on the network. The length of the jitter buffer directly effects the voice delay between

MultiVOIP gateways.

Minimum Jitter Value

60 to 400 ms

The minimum dynamic jitter buffer of 60 milliseconds is the minimum delay that would be acceptable over a low jitter network. Default = 150 msec

determines how quickly the length of the Dynamic Jitter Buffer is changed based on actual jitter encountered on the network. Selecting the minimum value of 0 means low voice delay is desired, but increases the possibility of jitterinduced voice quality problems. Selecting the maximum value of 12 means highest voice quality under jitter conditions is desired at the cost of increased voice delay.

Channel Associated Signaling (CAS) is a method of incorporating telephony signaling info into a T1 voice/data stream. In CAS, the signaling bits (the A, B, C, and D bits) are multiplexed into the signal stream of each T1 channel. (By contrast, in Common Channel Signaling (CCS), one channel handles signaling for all other channels.) Each CAS protocol defines the states of the signaling bits during the various stages of a call (IDLE, SEIZED, ANSWER, RING-ON, RING-OFF).

The CAS protocol code allows the VOIP to interact properly with the PBX or central-office switch that it serves.

If a user has an old MultiVOIP unit (with a firmware version lower than 4.08), and wants to upgrade to 4.08, the latest CAS file (4.08) should also be downloaded into that MultiVOIP unit. The new CAS file ensures proper operation between the MultiVOIP and a PBX.
