Configuration Note11. IntroductionIntroductionThis document describes how to setup the Mediant 1000 MSBG device to work withthe Gamma Telecom SIP Trunking and Microsoft Lync Communication platform.This configuration note is intended for Installation Engineers or AudioCodes andGamma Telecom Partners who are installing and configuring the Gamma TelecomSIP Trunking and Microsoft Lync Communication platform to place VoIP calls usingthe AudioCodes gateway.The AudioCodes Mediant 1000 MSBG device was used to implement this solution.The Mediant 1000 MSBG is a networking device that combines multiple servicefunctions, such as a Media Gateway, Session Border Controller (SBC), Data Routerand Firewall, LAN switch, WAN access, Stand Alone Survivability (SAS) and anintegrated general-purpose server. The Mediant 1000 MSBG device offers enhanceddialing plans and voice routing capabilities along with SIP-to-SIP mediation, allowingenterprises to implement SIP Trunking services (IP-to-IP call routing) and IP-basedUnified Communications, as well as flexible PSTN and legacy PBX connectivity.Note: The scope of this document does not cover security aspects for connectingthe SIP Trunk to the Microsoft Lync environment. Security measures shouldbe implemented in accordance with your organization’s security policies. Forbasic security guidelines, see the ‘AudioCodes Security Guidelines’.Microsoft Lync and Gamma Telecom SIP Trunk9June 2011

Microsoft Lync and Gamma Telecom SIP Trunk2.4TopologyThe procedures described in this document describe the following example scenario: An Enterprise has a deployed Microsoft Lync server 2010 in its private networkfor enhanced communication within the company. The enterprise decides to offer its employees Enterprise voice and to connect thecompany to the PSTN network using the Gamma Telecom SIP Trunking service. AudioCodes Session Border Controller (SBC) is used to manage the connectionbetween the Enterprise LAN and the Gamma Telecom SIP trunk.The “session" refers to the real-time voice session using IP SIP signaling protocol.The "border" refers to the IP to IP network border between the Microsoft Lyncnetwork in the Enterprise LAN and the Gamma Telecom SIP trunk in the publicnetwork.Figure 2-1 below illustrates the interoperability topology between the Microsoft LyncServer 2010 LAN and the Gamma Telecom SIP Trunking site.The setup requirements are characterized as follows: While the Microsoft Lync Server 2010 environment is located on the Enterprise'sLocal Area Network (LAN), the Gamma Telecom SIP Trunks are located on theWAN. The internal data routing capabilities of the Mediant 1000 MSBG device are used.Consequently, a separate WAN interface is configured in the LAN. Microsoft Lync Server 2010 works with the TLS transport type, while theGamma Telecom SIP trunk works on the SIP over UDP transport type. Transcoding support: Microsoft Lync Server 2010 supports G.711A-law andG.711U-law coders, while the Gamma Telecom SIP Trunk also supports theG.729 coder type.AudioCodes Mediant 1000 MSBG12Document #: LTRT-40700

Configuration Note33. Configuring Lync Server 2010Configuring Lync Server 2010This section describes how to configure the Lync Server 2010 to operate with theMediant 1000 MSBG. This section describes the following procedures:1.Configuring the Mediant 1000 MSBG as a ‘IP/PSTN Gateway’. See Section 3.1on page 15.2.Associating the ‘IP/PSTN Gateway’ with the Mediation Server. See Section 3.2 onpage 20.3.Configuring a ‘Route’ to utilize the SIP trunk connected to the Mediant 1000MSBG. See Section 3.3 on page 25.Note: Dial Plans, Voice Policies, and PSTN usages are also necessary for enterprisevoice deployment; however, they are beyond the scope of this document.3.1Configuring Mediant 1000 MSBG as an ‘IP/PSTNGateway’This section describes how to configure the Mediant 1000 MSBG as an IP/PSTNGateway. To configure the Mediant 1000 MSBG as a IP/PSTN Gateway and associating itwith the Mediation Server:1.On the server where the Topology Builder is located, start the Lync Server 2010Topology Builder: Click Start, select All Programs, then select Lync ServerTopology Builder.Figure 3-1: Starting the Lync Server Topology BuilderMicrosoft Lync and Gamma Telecom SIP Trunk15June 2011
