Hold is not working for Lync 2013 with CUCM version 8.6 RRS feed

  • Question

  • Lync calls can't be put on hold when we are using Cisco Call Manager 8.6 and Media By pass enabled.

    If we disable Media by pass, its working fine, but when enable it back, again it stopped working.

    Can somebody help me on this, thanks in advance.

    Regards,

  • Hi ,

         here you can find some tip and limitation CISCO integration , also if your version is not listed :

    http://technet.microsoft.com/en-us/lync/gg131938.aspx

    Configuration Notes for CUCM UCM 7.0.1.11000 and lync 2013:

    1. On the Cisco IP-PBX, configure MTP to enabled and PRACK to disabled (the default for PRACK).
    2. On Lync Mediation Server, Media Bypass is set to enabled. RTCP and REFER are set to disabled, as Cisco doesn't send RTCP messages and REFER is not supported by this IP-PBX without a Referred-By header.

    Known Limitations for CUCM UCM 7.0.1.11000 and lync 2013:

    1. When a Lync user transfers a PBX call to another PBX user, the local PBX phone will still show connected to the first Lync user.
    2. Comfort noise generation is not supported. As a result, comfort noise is not played on Microsoft Lync.
    3. When a Lync user configures call forward or simul-ring to a PSTN IVR number, the calling party will not hear early media played from the IVR.
    4. CUCM will not send OPTIONS, impacting failover scenarios as the IP-PBX cannot determine Lync's state until a call is offered.

    Configuration Notes for  UCM 8.5.1.12900 and lync 2010:

    1. On the Cisco IP-PBX, configure MTP to enabled and PRACK to enabled.
    2. On Lync Mediation Server, Media Bypass is set to enabled. RTCP is set to disabled, as Cisco doesn't send RTCP messages. REFER should be set to enabled, as REFER is supported by this IP-PBX.

    Known Limitations for UCM 8.5.1.12900 and lync 2010:

    1. Comfort noise generation is not supported. As a result, comfort noise is not played on Microsoft Lync. When a Lync user configures call forward or simul-ring to a PSTN IVR number, the calling party will not hear early media played from the IVR.

    let us know if with these conf , you'll solve .
