Microsoft Lync and ThinkTel SIP Trunk

AudioCodes Mediant E-SBC Series 12 Document #: LTRT-38110

2.4 Deploying the E-SBC (Typical Topology)

Procedures in this document show how to deploy the E-SBC in this example scenario:

 An enterprise deploys Microsoft Lync 2010 in its private network for enhanced

communication within the enterprise.

 The enterprise decides to offer its employees enterprise voice capabilities and to

connect the enterprise to the PSTN network using the ThinkTel SIP Trunking service.

 AudioCodes' E-SBC (Enterprise Session Border Controller) is used to manage the

connection between the Enterprise LAN and the ITSP SIP trunk.

Session = the real-time voice session using IP SIP signaling protocol.

Border = the IP to IP network border between the Microsoft Lync network in the

Enterprise LAN and the ThinkTel SIP trunk in the public network.

The figure below shows the E-SBC device managing the connection between Microsoft

Lync Server 2010 LAN and the ThinkTel SIP Trunking site.

Figure 2-1: Topology

2.5 Setup Requirements

Setup requirements are:

 Microsoft Lync Server 2010 environment is located in the enterprise's Local Area

Network (LAN); ThinkTel SIP Trunks are located on the WAN.

 Microsoft Lync Server 2010 functions with TLS transport type; ThinkTel SIP trunk

functions on the SIP over UDP transport type.

 Transcoding support: Microsoft Lync Server 2010 supports G.711A-law and G.711U-

law coders; ThinkTel SIP Trunk also supports G.729 coder type.

 Microsoft Lync Server 2010 functions with the SRTP media type, while the ThinkTel

SIP trunk functions on the RTP media type

 Microsoft Lync Server 2010 functions with Media Bypass Enabled.

2.6 Known Limitation

A limitation that occurred in interoperability tests:

 Microsoft Lync Server 2010 is configured with the Refer feature disabled. It's disabled

because the ThinkTel SIP trunk doesn’t support Refer SIP messages.
