Lync 2010 and Cisco CME 8.2 Issues

    질문

  • Hello,

    I have integrated Lync 2010 and a Cisco UC540 with CME 8.2.

    I am having trouble with Lync clients obtaining an outside dial tone.

    The SIP trunks run into the Cisco UC540 CME 8.2 - Internal calls from Lync to CME extensions work fine, but I cannot get Lync extensions to gain a dial tone to make outbound calls from the SIP trunk on the CME.

    I have followed pretty much every Lync to CME integration how to on the net.

    Has anyone done this before?

    Anyone have any advice as to how to debug or troubleshoot what the issue actually is??

    Thanks,

    Bradford Giosa

  • CME is not a supported IP-PBX, see the UC Open Interop Page - Supported IP PBX'es

    That been said, if you just want to use your CME device as a gateway, it should run a supported IOS version: 15.1(3)T, 12.4(24)T or 12.4(15)T3. More details can be found : UC Open Interop Page - Direct SIP

  • Ruben,

    Thanks so much for you reply and the information.

    So does this guide issued from MS not apply because it is CUSC and not CME?http://www.microsoft.com/download/en/details.aspx?id=26800

    If so what are the differences between the two, CME and CUSC, that allows Lync to work with one but not the other?

    Is it worth the switch (economical) to CUSC from CME for the Lync interoperability?

    Thanks,

  • What do you mean with CUSC?

    Do you have command line configuration options on this 540 series CME or is it GUI only? You'll need command line options to configure it as a basic gateway for Lync.

    If you ask me, the best way would be migrating your voice entirely to Lync and if possible use your UC540 as the voice gateway, but I'm a bit biased :)

  • The UC540 is just a baby router with CME as I understand it, so it should work.

    Whats CSUC, not heard of that before?

    Simple questions.

    What port are you running the SIP trunk on?

    Have you set it to tcp?

    Can you make calls from CME to Lync?

    Can you make calls from Lync to CME?

    In both cases can you run Lync logging and grab the logs

    thanks
