The specific test configuration is shown in Figure 1 below. This configuration ensures proper
SIP call handling between the customer-supplied voice platform and the Integra Telecom
equipment and network.

AudioCodes Mediant 1000 MSBG and Microsoft Lync Test Configuration
Note that some ‘schools of thought’ like to consider everything outside of or beyond the IP PBX itself to be part of the
PSTN. For this testing, the beginning of the PSTN does not matter; as ‘in to’ and ‘out of’ the IP PBX are the more
important considerations.
The Lync server deployment configuration and the desired interconnection to the MSBG will
vary by customer needs and requirements. Therefore, an assumption is made that the desired
configuration is compatible with the MSBG; consulting AudioCodes and Microsoft technical
support as needed. In addition, it is assumed that the Lync topology has been defined, saved,
and published. Finally, the end-user client users are correctly identified with enterprise voice
enabled and properly configured.
In this configuration document, the Lync server deployment was configured for TCP (not TLS)
transport to and from the MSBG. The signaling port was set to 5060 as well. Lync used a private
IP network addressing scheme. The MSBG performed NAT transversal (to and from public IP
space) in addition to the transport protocol conversion (i.e., to UDP on the WAN).
The sections below step through the menu tree in the MSBG. Note that the order of the sections
and screen captures are not necessarily in the order of needed provisioning. They are provided
in order of the menu tree to assist with data fill and configuration at the needed time. Any
section not detailed below was not changed from default or does not apply to the configuration.
