3 Introduction
This document provides a configuration guide for Sonus SBC 5000 Series (Session Border Controller) when
connecting to a Verizon SIP Trunk and Microsoft Lync 2013 Mediation Server.
The Sonus SBC 5200 is a Session Border Controller that connects disparate SIP trunks, SIP PBXs, and
communication applications within an enterprise. It can also be used as a SIP routing and integration engine.
The Sonus SBC is the point of connection between the Microsoft Lync 2013 Mediation Server and the Verizon
SIP Trunk.
3.1 Audience
This technical document is intended for telecommunication engineers with the purpose of configuring both the
Sonus SBC 5xx0 and aspects of the Microsoft Lync 2013 Mediation Server product. There will be steps that
require navigating the third-party and Sonus SBC Command Line Interface (CLI). Understanding the basic
concepts of IP/Routing and SIP/RTP is also necessary to complete the configuration and for troubleshooting, if
necessary.
This configuration guide is offered as a convenience to Sonus customers. The specifications and information
regarding the product 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,

4 Configuring Sonus SBC 5000 Series
This section describes how to use the Sonus Command Line Interface (CLI) to configure and manage the SBC
5000 Series.
The SBC can equally be configured and managed by the Embedded Management Application (EMA), which is a
Web-based interface management system for the Sonus SBC 5000 Series. However, documentation of the
equivalent configuration steps via EMA is beyond the scope of this guide.

Figure 2: SBC 5xx0 SIP Trunk Diagram
The above diagram also shows an optional Fax Trunk Group. Fax machines typically get their own Trunk
Group(s) which allows Fax-specific Packet Service Profile (PSP) and IP Signaling Profile (IPSP) configurations
without affecting non-Fax devices. While this document shows a Fax-specific Trunk Group, it does not have a
Route or Routing Label to use it. Call Routing to a specific Fax Trunk Group is usually done by called/calling
number routing (vs. trunk group routing) which is beyond the scope of this document.
The Fax Trunk Group can share the same SIP signaling interface and Zone on the SBC.
Lync 2013 only supports SIP over TCP (or TLS). The preference to control the SIP transport protocol is
configured in the IP Signaling Profile, which is applied at the Trunk Group level. This allows the proper SIP
signaling transport to be used for both Lync and Fax machine even though they use different transport protocols
with the same SIP signaling interface (SIP Signaling Port) on the SBC 5000.

4.2 SBC Naming Conventions
SBC Configuration
4.2.1
The SBC has both a System Name and a Compute Element (CE) Name (also referred to as a Host or Element
Name) whose differentiation is relative to an High Availability deployment (one SBC active, one SBC standby).
Each SBC server in an HA pair will have its own unique CE Name, while the HA pair will have a single System
Name. Even an SBC deployed in standalone mode will have a separate System Name and CE Name.
To follow Sonus best practice naming conventions, each server’s CE Name will usually have a simple “a/b” suffix
appended to the System Name:
SBC System Name SBC CE Name (active) SBC CE Name (standby)
SBC01 SBC01a SBC01b
Internal side Configuration
4.2.2
Unique address contexts, other than “default”, are only needed when using overlapping IP address space. This
deployment assumes no such overlapping IP space, thus all configurations are in addressContext “default”.

SIP Max PDU Size
4.4.1
Increase the Maximum PDU size to accommodate larger SIP packets.

SIP Domain
4.4.2
Configure SIP Domain Name.
set global sipDomain LYNC2013.SONUSNET.COM commit
IP Access Control Lists
4.4.3
Configure IP Access Control list entries. IP Access Control Lists (ACLs) are filters provisioned to protect the SBC
from attacks by blocking IP traffic that may be harmful to the network. ACLs allow users to specify rules to permit
or deny packets into the SBC.
ACLs must be configured on all Test Environment SBC interfaces that are connected to some untrusted network
element. (Usually only those interfaces that connect directly to the internet, as connections that go thru the
Sonus corporate firewall should be protected by that entity's ACL rules.) In any case, applying ACL rules on all
SBC interfaces is a best practice.

UDP Port Range for RTP (media)
4.4.4
The Sonus SBC 5000 series defaults to using the UDP port range of 1024-65148 for RTP (media) traffic. Many
enterprise networking devices, including security devices may assume a range of 16384-32767. The following
configuration modifies the SBC to work within that more limited range with no changes to the existing devices.
set system media mediaPortRange baseUdpPort 16384 maxUdpPort 32767 commit
Tone and Announcement Profile
4.4.5
If required SBC 5xx0 can provide a ringback tone.
This is achieved by creating a Tone and Announcement Profile and assigning Tone DSP resources to allow the
SBC to provide local ring back when needed.

Tone DSP Resources
4.4.6
Configure the DSP resources on the SBC for Tone and Announcement support. This configuration only applies if
the SBC has been deployed with DSP resources.
set system mediaProfile compression 90 tone 10 commit
Codec Entry – G.711u
4.4.7
Create a Codec Entry for the G711u codec with DTMF Relay configured for RFC2833, so that DTMF information
will be carried in the audio path as RTP events (e.g. 2833 method).

4.5 Internal side SBC configuration
IP Interface Group for Lync 2013
4.5.1
The below configuration is for a Sonus 52x0 system using a single port for Internal connectivity (the Sonus
convention is to use Media 2 and Media 3 ports for Internal connectivity). A similar configuration (not shown) for
the Sonus 51x0 system, which only has a total of two Media ports, would use the Media 1 port for Internal
connectivity per Sonus convention. SBC 5000 Media ports do not have dedicated Internal/External roles and,
while recommended, the Sonus convention does not need to be followed. For more information on Media port
deployment options or other network connectivity queries, refer to the
SBC 5000 Network Deployment Guide
or
contact your local Sales team for information regarding the Sonus Network Design professional services
offerings.
Create an IP Interface Group for SIP Signaling and RTP Payload for Lync 2013 and assign interfaces, including
IP addresses.

4.10 Global Call Routing Configuration
Lync 2013 Mediation Server Routing
4.10.1
A Routing Label (RL) is a user-named object that contains a list of one or more next-hop peers - defined as
Routing Label Routes - that can reach a specified destination.
Sonus – Network Design Group
30 of 54
Copyright © 2014, Sonus and/or its affiliates. All rights reserved.
A Routing Label Route (RLR) defines a single peer (Trunk Group + IP Peer) to which the call can be delivered.
There may be many Routing Label Routes (1 to n) in a Routing Label.
For each call placed to a destination Routing Label, the SBC will advance through the list of peers (RLRs) until
the call is completed or the list is exhausted. The RL's Prioritization Type determines the order in which the list
will be processed.
Routing Labels are then assigned within the Route entity.

6 SBC and Lync 2013 Specific Configurations
Depending upon the type of call scenario desired will determine what settings are required for the SBC and
Microsoft Lync 2013 product.
6.1 Initial Setup for All Calls
DM/PM Rules
6.1.1
Digit Manipulation rules were required for the purpose of mapping preconfigured Lync 2013 user extensions
to established Verizon SIP Trunk DIDs. This is not expected to be a requirement for deployment scenarios.
For details of the DM/PM configuration please refer to Appendix A.
10-Digit Dialing
6.1.2
Normal calling pattern was to dial all 10 digits of a national number. 7 digit and extension dialing was not
included as part of the SIP Trunk interoperability testing. Other dialing patterns tested include Operator
Assistance calls, N11 codes, local/toll calls, and international calling.
6.2 Initiating Transfers with REFER
Call transfer via REFER method – Not Supported
6.2.1
Microsoft Lync Server 2013 is incompatible with Verizon network call transfer using the SIP REFER
Method. The contents of the REFER-TO Header in the SIP REFER message sent by Microsoft Lync are not
acceptable to the Verizon SIP Trunk.
6.3 Initiating Transfers with Re-INVITE
Call transfer via Re-Invite method
6.3.1
Transferring a call to another phone number is supported via the RFC3261 method. No special flag is
required to be set for this method. Ensure that on MS Lync 2013 under the “Trunk Configuration” element
that REFER support is set to “none”.

6.4 Call Hold
Call Hold via RFC3264
6.4.1
Placing a call on hold is via the RFC3264 method. This method is the preferred method for connections on
Verizon SIP Trunks. This method involves sending a Re-INVITE with the parameter “a=inactive”. No special
flag is required to be set for this method.

7 Appendix A – DM/PM Criteria and Rules
7.1 DM/PM Criteria
Lync 2013 to Verizon SIP Trunk number manipulation
7.1.1
Due to the nature of the test lab Lync 2013 Mediation Server in relation to other equipment in the test
environment, it was mandatory to create Digit Manipulation Criteria and Rules to map the Verizon
assigned SIP Trunk DIDs to pre-existing DIDs on Lync. What follows is a description of these settings. It is
not expected that DM/PM criteria and rules would be required in a typical customer deployment.
7.1.1.1
DM/PM Criteria – Lync 2013 numbers
DM/PM Criteria for Lync extensions. These are pre-configured numbers in the lab environment. From the
DM/PM Rules and call flow perspective these are considered the called numbers.
