How to Extend Lync 2013 to Yeastar TG Series (Summary)

1. Introduction

Brief introduction of the Lync Server installed, and the target achieved in this manual.

Brief Introduction:

This is a standard version of Lync installed in windows 2008 R2 SP1 standard (64bit). It requires two computers to install, one for DC and the other one for Lync. Since TCP/TLS is supported by Lync only, which doesn't match the general trunks we get like PSTN/SIP (UDP)/BRI/GSM or others, a translator like Yeastar TG is needed to offer GSM channels.

Basic Information:

  • IP of DC:
  • IP of Lync:
  • IP of Yeastar TG:
  • FQDN: (Front end server, SQL and mediation pool are installed here)
  • Account: harry, extension: 800,
  • Default TCP port: 5060 (Yeastar TG), 5068(Lync)
  • IVR/ Queue number of Lync: +888


  • Making outbound calls from Lync server via the GSM trunks of Yeastar TG directly.
  • Making inbound calls from GSM trunks to reach the IVR or Queue of Lync 2013.


2. Create topology to Lync 2013 and publish it

Open the topology you have got from the builder. If you haven't got one, please create
and publish it before adding a new gateway.
