Lync 2010 und Avaya CS1000 UEXT 488 Not acceptable here RRS feed

  • Question

  • Hello,

    my configuration

    Lync 2010 -> SIP Trunk  <- CS1000E Rel. 7.5

    all works as expected, only if I make a call from Lync Client to an extension in CS1E with dual forking and the call will be established at the UEXT extension (f.e. mobile phone).  The call will be disconnected immediately. In the Lync Trace I get 488 Not acceptable here:

    Any Ideas?

  • Hi Wallae,

    From the log, we got the reason “Gateway side Media negotiation failed” and the validation error “call hold not allowed for initial INVITE offer”.

    Here I suggest you to have a look at the media list for the signally groups and call routing tables of your gateway. You can refer to this post.

    And please also check the ports for Inbound and Outbound.

    If any, please feedback.

  • It looks like, the configuration between Lync to CS1E is wrong, you can try to disable referer support and mediabypass.

  • I have already tested to disable refer and mediabypass, but it wont fix my problem. Strange is that all outgoing calls works as expected, only if UEXT ext. will establish the call.
