Cisco CCM 8.0 to Lync Enterprise Sip Trunk RRS feed

  • Question

  • Hi.

    We have a new Lync deployment and we are at the stage of setting up enterprise voice using a sip trunk with a Cisco Call Manager (V 8.0). We have setup the trunk (currently pointing to one of the FE server where the Mediation rol resides).

    We are able to call out from Lync to the Cisco, all routes are working fine. From the cisco to lync we have problems. When calling one of the defined users (+63634) from one of the cisco extensions (65397) we get a 503 service unavailable (when sniffed at the mediation server). Using lync logging tool, particularly looking at the mediation logs I see these errors:

    1) Start-Line: GatewayStream Endpoint Allocation failed with ReasonCode: 8

    2) Start-Line: Media stack failed gateway side endpoint allocation because of a non-bandwidth related issue.

    3) Start-Line: Error GW side endpoint allocation for Start failed with reason code 10010.

    4) Start-Line: Exception: Microsoft.Rtc.Internal.Media.ChannelException: Cannot get the channel parameter.
       at Microsoft.Rtc.Internal.Media.RtpChannel.EngineGetChannelParameter(CChannelHandle hHandle, UInt32 ulParamName, UInt64* pulParamValue)
       at Microsoft.Rtc.Internal.Media.RtpChannel.get_QoeXMLMediaLine()

       at Microsoft.RTC.MediationServerCore.GatewayStream.InternalDispose() Inner hr : 0x80004005

    Media bypass is enabled. CAC is not enabled. Refeer support is disabled..

    Thanks in advance.

  • Hi,

    Looks like the +63634 is not a DID number. I think you need to use a DID number with the extension. You can run lync server logging tool on the lync FE server to get the call trace and find why the call failed.

    Please refer the following document about integrating CUCM with Lync server:

  • Hi,

    If you call a number with a "+", this call will be route the PSTN gateway. What's the Lync user line URI? If you assign the extension number for the lync client, you need the format for Lync Line URI:+(DID number);ext=(extension number).

  • the current format for the user URI (Line URI) is: Tel:+63634;ext=63634

    I also changed that to simply Tel:+63634 without the extension. If this was a routing issue, would the error be 503 service unavailable or 404 not found??
