2 Purpose
This guide is for configuring the necessary options for interconnecting NET’s UX2000 SBC between XO’s
SIP Trunk offerings and Microsoft’s Lync Server 2010 over the public internet. The UX2000 provides a
secure method of isolating the internal corporate data network from the publicly reachable SIP Trunk
offerings. The UX2000 is located between the Public Internet and the internal WAN/LAN network as
shown below:
Figure 1 Typical Lync Server 2010 to XO SIP Trunk Deployment

3 Completing SIP Trunk Task on UX2000
Configuring the UX2000 is done through the UX2000s integrated web server. This guide assumes that the
operator has already done the initial configuration positioning the UX2000 on the IP network. To start the
configuration process use a standard web browser to connect to the IP or FQDN address of the UX2000.
Supply the username and password to complete the login process.
3.1 Prerequisites
The following will be required to complete the configuration of the UX2000 SIP Trunk Task:
a. Access to the Certificate Authority to download the root certificate and sign and download the user
certificate for the proper TLS operation between the UX2000 and the Lync 2010 Server(s)
b. FQDN of the Lync 2010 Mediation Server or Server pool
c. IP Address(s) of the XO Communications SIP Signalling destination server
d. FQDN of the UX2000
3.2 Initial Task configuration
The Initial Task configuration is a step by step process that will complete the steps to position the UX2000
between XO’s SIP Trunk and Microsoft’s Lync Server 2010. This task will install the necessary TLS
Certificates and create SIP components and call routing basics.

Figure 2 Initial Task Configuratio n
3.3 Root Certificate
Using the web browser navigate to the Task tab and click on the ‘Microsoft UC Setup/Lync 2010 Setup’
link on the left pane. This will start the task to setup the UX2000 to be configured between the XO SIP
Trunk and the Lync Server 2010 components.
The page that loads will have 4 sub tabs located in the right configuration pane. Click on the ‘Trusted CAs’
tab and then the left box with the red up arrow icon. This will prompt for the import of the Root
Certificate. There are 2 options for the import type, DER and PEM. DER is used to import a binary type
format certificate and will open a file explorer to import the certificate. The PEM type is used to import an
ASCII type format. To use the PEM type, first open the certificate file with a text editor such as Microsoft
Notepad and then copy and paste into the text box as shown:

4 Configuring Public Ethernet Port and IP Addressing
The UX2000 SBC mediates between a company’s internal IP network for SIP signalling and SIP media and
the external public IP network to the XO SIP signalling and media servers. The internal IP addressing is
setup during the initial installation of the UX2000 SBC and is outside the scope of this Configuration
Guide.
4.1 Configuring the Public Ethernet Port
There are 5 Ethernet ports on the front of the UX2000 SBC. The far left (Admin) is reserved for
administrative use during the initial configuration. The 4 other ports can be used for normal SIP signalling
and media. Port 1 will be configured during the initial setup of the UX2000 SBC and will normally be used
for the company’s internal IP network.

The IP Default route is required so that the UX2000 SBC will know where to send IP packets into the
public IP network. From the Settings/Protocols/IP/Static Routes click on the green ‘+’ sign to add the
route. This will open the dialog for the IP Route. Complete the dialog with the following information:
Figure 9 IP Default Route
Destination IP: Enter ‘0.0.0.0’
Mask: Enter ‘0.0.0.0’
Gateway: Enter the IP Address of the IP Default Router
Metric: Enter ‘1’
Once configured click ‘OK’ to apply the configuration.
UX2000 SBC XO SIP Trunk Lync Server 2010 Configuration Guide
17
Figure 10 Public IP Default Route
4.4 Configure Internal Private IP Static Route
Internal IP Static Routes may be required if the UX2000 SBC needs to communicate with multiple internal
private IP addresses. These static routes have to be deterministic because there can be only one default
route and this is used on the public side. If there are multiple internal networks then multiple static
routes will be required. The examples below show static routes for a private 10.0.0.0 network and a
private 192.168.0.0 network:

5 Lync Server 2010 Configuration
Lync Server 2010 will need to be configured to support the UX2000 SBC in order to communicate with the
XO SIP Trunk. This section covers the addition of the UX2000 into the Lync Server topology and adding the
UX2000 to the Lync Server 2010 routing. XO SIP Trunk DIDs will be assigned to a Lync users account and
the commands will be shown how to add an analog contact with a XO SIP Trunk DID.
This section assumes that the Lync Server components have been installed along with Lync users. The
user should be familiar with Lync Server Topology Builder, Lync Server Control Panel and Lync Server
management Shell. This section does not cover the basic installation of Lync Server 2010.
5.1 Adding UX2000 SBC to Lync Server Topology
The Lync Server topology needs to be modified by adding the UX2000 SBC as a Gateway device. The
Gateway device will be the interface to the XO SIP Trunk.
Open Lync Server Topology builder and load the current topology. Expand the topology and click on the
‘PSTN Gateways’ link in the left hand pane. This will provide the link in the right hand pane ‘New IP/PSTN
Gateway’. Click on this to open the dialog below:

Figure 17 PSTN Gateway and PSTN Usages
At this point commit these changes to the topology.
5.3 Configuring Assigned DIDs to Lync Users
In order for Lync users to be called directly from the PSTN, the Lync users will have to have the XO SIP
Trunk DID numbers assigned. This is done in the User section of Lync Server Control Panel.
Open the specific Lync user in Lync Server Control panel that will have a DID assigned to it. Configure the
DID in the Line URI configuration as shown below:
UX2000 SBC XO SIP Trunk Lync Server 2010 Configuration Guide
24
Figure 18 Lync User DID Setting
Click ‘Commit’ to complete the changes.
5.4 Creating Analog Contacts with XO SIP Trunk DIDs
In order for analog devices to be called directly from the PSTN, the analog devices will have to have the
proper XO SIP Trunk DID assigned to it.
This section does not go into details on configuring analog devices. Please see the Lync Server 2010
documentation for further details.
Open Lync Server Management Shell. Below is an example of how to create an analog contact as a fax
machine and a XO SIP Trunk DID number of 14255554321:

6 UX2000 Telephony Routing Process
The telephone routing process in the UX2000 moves calls received on one Signaling Group (SG) to an
outbound SG. While the call is moving the number or name may be translated and additional lookups can
be done to ensure the call is routed properly.

6.1 Signaling Groups
The SG is the first place an incoming call will reach the UX2000. The Signaling group will direct the call to
the Routing Table as shown below:
Figure 21 Signaling Group
6.2 Call Routing Table
The Call Routing Table will send the Called and Calling Party information elements to a Translation Table
so that they can be modified if required to match the destination systems format. Once the translations
have been completed the Route Table will then route the call to the applicable SG for the destination
system.
UX2000 SBC XO SIP Trunk Lync Server 2010 Configuration Guide
27
Figure 22 Call Routing Table
6.3 Translation Tables
Translation tables are used to modify the called and calling party information elements among other
elements that are pertinent to proper call handling between the origination and destination servers. The
basic translations rely on the use of Regular Expressions as the numbers/names are changed from what is
received to what is sent to the destination. Translation tables must have a matching entry format in order
for the call to be routed to that route. If there are no matching Translation table entries the call will be
returned back to the Routing table so the next Route entry can be tried for a match. This will happen as
long as there are Routes in the Route table to try. If all Routes have been tried with no matches in the
Translation table(s) the call will fail.
UX2000 SBC XO SIP Trunk Lync Server 2010 Configuration Guide
28
Figure 23 Translation Tables
Most translation table entries for a SIP Trunking application will be used for matching Lync Server 2010
requirement for called and calling numbers to be in E.164 format. Below are examples to match XO
number format to Lync Server 2010 number format.
This example is used to translate a called number from Lync 2010 Server in E.164 format to a US 10 digit
number for routing into the XO SIP Trunk:
Input Field
Type: Called Address/Number – Used to capture the numeric portion of the Dialed Number
Value: ^\+1(\d{10})$ - Regular Expression that looks for the +1 at the start of the Dialed Number
and then captures the 10 digits that follows between the open and close parenthesis
Output Field
Type: Called Address Number – Identifies the Information Element that the Input Field Type
should be translated to
Value: \1 – Identifies the open and close parenthesis that should be carried over from the Input
Value Field

Value: ^(\d{10})$ - Regular Expression that looks for the +1 at the start of the Dialed Number and
then captures the 10 digits that follows between the open and close parenthesis
Output Field
Type: Called Address Number – Identifies the Information Element that the Input Field Type
should be translated to
Value: +1\1 – Prepends ‘+1’ and Identifies the open and close parenthesis that should be carried
over from the Input Value Field

7 Media Configuration
The UX2000 initial configuration task from Section 1 of this guide will setup the required media settings
for both the Lync 2010 Server and the XO SIP Trunk. Media lists will be created and applied to the
appropriate SGs. Below are examples of a typical Media configuration:

Figure 29 Media List (cont) Show ing Digit Relay Settings
Figure 30 Signaling Group Showing Media List Selection
8 Enabling Media Transcoding
Media Transcoding can be used for changing both codec and DTMF digit transfer methods. Since Lync
2010 Server does not support both G.729 and inband DTMF digit transfer methods the UX2000 can be
UX2000 SBC XO SIP Trunk Lync Server 2010 Configuration Guide
33
configured to transcode one list to another list between the XO SIP Trunk and Lync 2010 Server. In order
for this to work properly there has to be a Media List for the XO SIP Trunk with G.729 and/or Inband DMF
digit transfer settings and another Media List with G711 (A or U law as required) with RFC2833 digit
transfer.
The actual Transcoding configuration setting is done at the Route Table. The example below is for a call
originating on the Lync 2010 Server using G711 and the matching Route table entry for XO has
Transcoding enabled and calls out the Media list that is used for the XO SIP Trunk:
Figure 31 Media Trancoding Configuration
9 Analog Support
Lync Server 2010 supports analog devices such as phones and fax machines in its topology. The devices
can be configured with DID numbers so that they can be dialed directly from the PSTN. The analog
devices are configured to home to a configured SBC or gateway in the Lync Server 2010 topology. This
means that the configuration on the homed device needs to be able to route calls to the analog devices
from Lync Server 2010 while also routing calls to the SIP Trunk.
UX2000 SBC XO SIP Trunk Lync Server 2010 Configuration Guide
34
9.1 Differences Between PSTN and Analog Call Routing
When analog devices are part of the Lync Server 2010 topology the UX2000 will have to be able to
recognize a call to an analog ATA from Lync Server 2010 and route these differently than calls to the SIP
Trunk. Calls from the SIP Trunk will all go to the Lync 2010 Server. The Route table in the UX2000 will have
to have knowledge of all analog numbers so these calls can be routed to an ATA instead of to the SIP
Trunk. All other numbers that are not recognized as analog devices will then be routed to the PSTN
through the XO SIP Trunk.

To support Analog devices additional configuration will be required. For each ATA an additional SIP Server
table and Signaling Group and Route table will be needed. The routing will be to send all calls from the
Analog devices to the Lync Server 2010. Also since the UX2000 does not currently support Analog
connections a separate ATA will be required.
9.2.1 SIP Server Table
The SIP Server table for the ATA is configured so that the UX2000 will know where to send analog calls to.
The SIP Server table is configured under Settings/SIP/SIP Server Tables. Click on the green ‘+’ to add the
name of the ATA. In the example below an ATA with the name of ‘Tenor 206’ has been added:

9.2.4 Modify Lync Server 2010 Routing Table to Add ATA Route
With the SIP Server, Translation Table and SG configured, the Routing table that routes calls from Lync
Server 2010 needs to be modified so that the calls for the ATA will be routed properly. This is done by
adding the ATA routes into the table.
Open the Lync Server 2010 Routing table by clicking on Settings/Call Routing Table. Click on the Call
Routing table for calls coming from Lync Server 2010, in this configuration it is the ‘Lync Server 2010
Routing’ entry. Once the table is opened click on the green ‘+’ sign to add the route to the table.
Configure the following to complete the dialog:
Description: Add a description to associate with this route
Number/Name Translation Table: Select the proper Translation Table from the dropdown, in this
case select the Translation configured above
Destination Signaling Group: Click ‘Add’ and then select the SG for the ATA
The completed dialog is shown below:

Figure 44 Adding ATA Route
Click ‘OK’ to complete the dialog and then click ‘Resequence’ at the top of the Route Table entries. In the
dialog that opens click on the route for the ATA and then click ‘Up’ to move this route to the top of the
table. This will ensure that the Route table will analyse the routes for the ATA first before the call is
routed to the XO SIP Trunk:

9.2.5 Add Translation Table for ATA
All Calls from the ATA will have to be routed to Lync Server 2010. A Translation table may be required to
match the default number format on the Lync Server 2010 (E.164). The Translation table below is used to
add a ‘+’ to the called number from the ATA:

10 Troubleshooting
The UX2000 provides various ways to troubleshoot call issues. The first is through visual analysis of
configured systems and active and certain archived alarms through the Monitor page. And the UX2000
can generate debug logs to be viewed locally, downloaded to a text editor or the debug logs can be sent
to a Syslog collector.
10.1 Visual Analysis
Clicking on the ‘Monitor’ tab will bring up a real time view of the current status of the configured SGs and
also a real time view of call status. Also, the current alarms will be shown in the ‘Alarm Window’ at the
bottom of the screen and the highest unacknowledged alarm color will show in the ‘Monitor’ tab.
10.1.1 Current SG Status and Call Activity
The top portion of the ‘Monitor’ display will show the current status of the SGs and their associated
channels. If a SG is down the SG will be colored Red as shown below for the XO SG:
Figure 49 XO SIP Trunk Down
There are many reasons a SG may be down. The far end equipment may be off line, there could be a
routing issue or there could be a configuration problem. The visual Monitor will provide a quick view on
where to start trouble shooting.
UX2000 SBC XO SIP Trunk Lync Server 2010 Configuration Guide

10.1.2 Current Alarms
The current alarms will also indicate problems. The alarms shown below posted as the XO SG went out of
service:
Figure 50 Alarm Status
10.2 Viewing Debug Logs
The UX2000 will continually record the last hour and 15 minutes of debug logs. These are split into 15
minute logs and can be viewed by clicking on the ‘Logs’ tab as shown below:
Figure 51 Debug Logs
The logs are ordered with the current log being written on top. When the current log reaches the end of
the recording period it will be rotated down from the top and a new log will start to write.
To view one of these logs click the blue box to the left of the file name. This will open a web based text
box that can be scrolled through to find certain debug information.
To download the log to either save or open in a text editor, click on the ‘Download’ link to the right of the
file information. This will open a dialog to either save to a file or open.
10.3 Sending Debug Logs to a Syslog Collector
To send debug information to a Syslog server, click ‘Settings/Logging Configuration/Remote Log Servers’.
Click on the green ‘+’ sign to add a Syslog collector. Complete the dialog with the following information:
Global Log Level: Set to the level required
Log Destination: Enter the FQDN or IP Address of the Syslog Collector
UX2000 SBC XO SIP Trunk Lync Server 2010 Configuration Guide
