Document Overview

This document provides a configuration guide for Sonus SBC 5XX0 series (Session Border Controller) when connecting to Microsoft Skype for Business.

This configuration guide supports features given in TDS_SfB_Server_2015_Infrastructure_Interoperability_Program_for_SBC.docx.

Introduction

The interoperability compliance testing focuses on verifying inbound and outbound calls flows between the Sonus SBC 5200 and Microsoft Skype for Business, using TCP, TLS and SRTP.

Audience

This is a technical document intended for telecommunications engineers with the purpose of configuring both the Sonus SBC and the third-party product. Some steps require navigating third-party as well as the Sonus SBC Command Line Interface (CLI). Understanding the basic concepts of TCP/UDP, IP/Routing, and SIP/RTP are also necessary to complete the configuration and for troubleshooting, if necessary.

Requirements

The following equipment and software were used for the sample configuration provided:

Third-Party Product Features

The following features and functionality were covered during compliance testing:

  • Incoming calls to the Enterprise site through the Sonus SBC 5200.
  • Outgoing calls from the Enterprise site through the Sonus SBC 5200.
  • DTMF tone transmission using RFC 2833.
  • Telephony features such as hold, resume, transfer, conference, and call forwarding.

Prerequisites

All the Skype Topology should be configured.

SBC is installed with correct version and also has valid License for TLS. 

Verify License

No special licensing is required for this test.

Configuration  - SBC Configuration

This section provides an overview of Sonus SBC 5200 configuration used during compliance testing.  The Sonus SBC 5200 is typically configured for customers by Sonus Networks.  The screen shots and partial configuration shown below, supplied by Sonus Networks, is provided only for reference.  Other configurations are possible. 

1. Global Configuration

 

1.1 Codec Entry

Create a Codec Entry with the supported codec on the network.

set profiles media codecEntry G711_2833_20
set profiles media codecEntry G711_2833_20 codec g711 dtmf relay rfc2833

commit


set profiles media codecEntry G711A_2833_20 law ALaw codec g711 packetSize 20 dtmf relay rfc2833
commit

 

1.2 RTCP

Configure RTCP interval.

set system media mediaRtcpControl senderReportInterval 5
commit

 

1.3 SIP Domain

Specify the global SIP Domain name.

set global sipDomain amuthusamy2-inl.sonusnet.com
set global sipDomain med.sonusent.in
set global sipDomain med1.testnetwork.com

1.5 DSP Resource Allocation

Configure DSP resources.

This configuration only applies if the SBC has been deployed with (hardware) DSP resources. If it was not, executing this configuration step has no negative impact. Subsequent configuration sections (Packet service profiles) do not attempt transcoding, so lack of compression resources will not impact the overall SBC configuration in this document.

3.10 Routing

Routing must be put in place to send calls to the correct destination. For the purpose of this scenario, trunk group routing was used, but additional routing options may be used.

Configuration of both standarf and username routes are done to ensure that no matter which way the called party is addressed (a number or username) the SBC will route the message to the Core.

Create Route entries for standard Trunk Group routing with Matching Criteria and a Routing Label destination.

set global callRouting route none Sonus_NULL Sonus_NULL standard 333 1 all all ALL none Sonus_NULL routingLabel SP_RL1
set global callRouting route none Sonus_NULL Sonus_NULL standard 444 1 all all ALL none Sonus_NULL routingLabel SP_RL2

4. TLS Configuration

Note

The following shows the only difference from previous section

Important Note
   
SBX5K does not support MKI. LYNC_IT tool does not take into account that SBX has not published MKI support in its SDP and still tries to validate SRTP as
SRTP with MKI BIT set. As a workaround, we publish MKI support in SDP and use this new debug xrm command to mark MKI bit in outgoing SRTP/SRTCP  streams and also factor it for incoming SRTP/ SRTCP streams.

This command is to be used only for LYNC certification or qualification in Customer Labs only. We do not recommend enabling this in production enviroment.
