Using the Gateway Computer Between the PSTN and

Microsoft® Lync™ Server 2010

This configuration scenario describes the necessary steps for configuring a gateway

computer that is directly connected to the PSTN via two T1 RBS links and also connected to

a Lync SBA server on the SIP side. This scenario has the following characteristics:

 There is no PBX between the gateway and the PSTN.

 The Lync Server is co-located with the gateway. Together, the Lync Server and the

gateway create a Survivable Branch Appliance Solution (SBA).

 The gateway is connected to an FXS (Foreign eXchange Subscriber interface) Analog

Telephone Adapter (ATA) via SIP. The FXS ATA is connected to analog phones or fax

devices.

 Internal extensions have four digits.

 The Lync Server routes calls to extensions 2201 and 2202 to the FXS ATA via the

gateway.

 The gateway blocks calls from the PSTN that have origination extensions of 2201 or

2202, because the Lync Server would treat these calls as calls from the FXS ATA

rather than calls from the PSTN.
