Lync not routing to PBX RRS feed

  • Question

  • Hi,

    I am trying to get Lync to route calls to my existing PBX a Cisco 1760 with a SIP trunk. However Lync seems to be trying to connect to the device on port 5070 even though I have specified 5060 in topology. Call coming into lync work fine from the 1760.

    I tried wiresharking the server, but it seems no traffic is even leaving the lync box to the 1760. :(

    Running Snooper there seems to be a SIP server time out error.

    I have checked that the mediation server is running, and that the LyncPool DNS name is actually valid. Help is appreciated.

    I accidentally used an incomplete FQDN when I created my FrontEnd server. Instead of LyncPool.mydomain.net I just used LyncPool. I had to remove the topology and front end server and re-provision the Lync installs.

  • Is there a port conflict with running the co-located mediation server on port 5060?

  • Hyperlight, restart the servers once you've verified the topology is pushed to it.

  • I have already tried. It still isn't sending traffic.

    I am thinking I will have to deploy a dedicated mediation server. I can't seem to find out whats causing this timeout.
