How to Extend Lync 2013 to Yeastar TE 100 (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 TE100 is needed.

Basic Information:

  • IP of DC:
  • IP of Lync:
  • IP of Yeastar TE100:
  • FQDN: (Front end server, SQL and mediation pool are installed here)
  • Account: harry, extension: 800,
  • Default TCP port: 5060 (Yeastar TE100), 5068(Lync)


  • Making outbound calls from Lync via the E1 trunk of Yeastar TE100 directly.
  • Making inbound calls from E1 trunk of TE100 to Lync server directly.


  • All number numbers dialed from Lync start with‍ “+”, we need to delete this before dialing out via TE100
  • “+” is needed to be added when dialing from TE100 to Lync server 2013.
  • TE100 can dial directly the IVR/Queue/Ring group number 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.

This is the window of lync 2013 Topology Buider:

You can change the trunk name to Yeastar TE100, or just keep it.

  • Listening port of IP/PSTN gateways: 5060
  • SIP Transport Protocol: TCP
