1 Document Overview
This Application Note describes the configuration steps required for the Sonus Session Border Controller (SBC)
1000 and SBC 2000 to interoperate with the Lync 2013 system and a SIP trunk group to PSTN.
The objective of this document is to describe the configuration procedures performed during interoperability
testing of SBC 1000 and SBC 2000 with Lync 2013 Server over SIP trunk to PSTN.
For additional information on Sonus SBC 1000 and SBC 2000 series, visit http://www.sonus.net
For additional information on Lync 2013, visit http://www.microsoft.com
1.1 Overview
The Sonus SBC 1000 and SBC 2000 Session Border Controllers are designed to use the same application
software, boot image, and Survivable Branch Appliance software. The SBCs differ in the number of physical
Ethernet connections and processing power, but otherwise are viewed from a software standpoint as identical.
The reference configuration described in the following sections was tested with an SBC 1000, but is fully
applicable to an SBC 2000.

2 Introduction
This document provides configuration guidance for the Sonus SBC (Session Border Controller) 1000 Series
when connecting to a SIP trunk group and a MS Lync 2013.
The Sonus SBC 1000 and SBC 2000 are Session Border Controllers which connect disparate SIP trunks, SIP
PBXs, and communication applications within an enterprise. The SBC can also be used as a SIP routing and
integration engine.
The Sonus SBC is the point of connection between the SIP trunk group to PSTN and the Lync 2013.
2.1 Audience
This technical document is intended for telecommunication engineers for the purpose of configuring the Sonus
SBC 1000 and SBC 2000, along with aspects of the SIP trunk group coupled with the Lync 2013 product. There
are steps that require navigating third-party and Sonus SBC Graphical User Interface (GUI). Understanding the
basic concepts of IP, routing, and SIP/RTP are necessary to complete the configuration or troubleshooting, if
necessary.
This configuration guide is offered as a convenient reference for Sonus customers. The product specifications
and information contained in this guide are subject to change without notice. All statements, information, and
recommendations in this guide are believed to be accurate, but are presented without warranty of any kind,
express or implied, and are provided “AS IS”. Users must take full responsibility for the application of the
specifications and information in this guide.

The figure above shows the equipment used for the integration and certification testing. The SBC 1000 is used to
route and facilitate calls between the PSTN and the Lync 2013 system.
The SBC 1000 under test has 2 Ethernet ports configured. The SBC 2000 can have up to 4 physical Ethernet
ports. For more information on Media port deployment options, refer to the SBC 1000 Network Deployment
Guide. Contact your local Sales team for further information or other network connectivity queries with the
Sonus Network Design professional services offerings.

3 Configuring Sonus SBC 1000 and SBC 2000 Series
The SBC 1000 and SBC 2000 share a common code base and user interface. In this example, we are using an
SBC 1000.

3.2 External Peer Side SBC Configuration
Node Interfaces
The Sonus SBC 1000 allows you to configure the Identification information, Physical Data Layer, and Networking
Layer for the Ethernet ports. If you want to change the IP address, you must configure the associated Logical
Interface or use the Modify Ethernet IP task found under the Tasks tab.

The following sections contain figures that show settings for the Ethernet connection between the Sonus SBC
1000 and Public internet.

SIP profile
SIP Profiles control how the Sonus SBC 1000/2000 communicates with SIP devices, and control important
characteristics such as: session timers, SIP header customization, SIP timers, MIME payloads, and option tags.
Shown below is the default SIP profile used for the SBC 1000 in this test.

Media Profile
Media Profiles allow you to specify individual voice and fax compression codecs, and their associated settings,
for inclusion in a Media List. Different codecs provide varying levels of compression, allowing one to reduce
bandwidth requirements at the expense of voice quality. For reference, the Media Profile used for the SBC 1000
is shown below.

SIP Remote Authorization Table
SIP Remote Authorization Tables contain the credentials required to answer SIP Challenges to
Requests sent to ThinkTel. The information to complete this table is provided from ThinkTel.

SIP Server Tables
SIP Server Tables contain information about the SIP devices connected to the Sonus SBC 1000/2000.
The entries in the tables provide information about the IP addresses, ports, and protocols used to
communicate with each server. The table entries also contain links to counters that are useful for
troubleshooting.
Figure 10: SIP Server Table

Sonus –Network Design Group
Signaling Groups
Signaling Groups allow telephony channels to be grouped together for the purposes of routing and shared
configuration. Calls are routed to Signaling Groups, as well as the location from which Call Routes are selected.
Signaling Groups provide the location from which Tone Tables and Action Sets are selected. In the case of SIP,
Signaling Groups specify protocol settings and link to server, media, and mapping tables.

Call Routing Table
Call Routing allows calls to be carried between Signaling Groups, which permits calls to be carried between
ports and between protocols (for example, ISDN to SIP). Routes are defined by Call Routing Tables and allow
for flexible configurations that determine how calls are carried and translated. Call Routing Tables are one of the
central connection points of the system linking Transformation Tables, message translations, Cause Code
Reroute, Tables, Media Lists, and the three types of Signaling Groups (ISDN, SIP and CAS).

Transformation Tables
Transformation Tables facilitate the conversion of names, numbers, and other fields when routing a call. For
example, Transformation Tables convert a public PSTN number into a private extension number, or a SIP
address (URI). Every entry in a Call Routing Table requires a Transformation Table. In addition, Transformation
Tables are configurable as a reusable pool that Action Sets can reference.
