Lync 2013 and Cisco VCS RRS feed

  • Question

  • The article http://blogs.technet.com/b/lync/archive/2013/03/16/video-interop-in-lync.aspx, states that Interop with Cisco VCS is possible with minor modification. Was this minor modification a code change or configuration change?

    Does anyone know?

  • It's definitely a code change, no level of configuration changes in the current VCS application will provide a working environment.  Cisco needs to update the VCS code to interoperate with new changes in Lync 2013 across SIP signaling, SDP media negotiation, RTCP, and even RTP.

    The H.264 SVC encoder/decoder that Lync 2013 clients and servers utilize is backward compatible with standards-based H.264 AVC code, but only at the media payload level.  The codecs themselves are not 100% compatible and require changes by the vendor to their products to communicate with Lync 2013.

  • Hi,

    Lync server 2013 supports H.264 codec. if VCS does support the same codec, you should be able to talk to the device without any problem.

  • Hi,

    Lync 2013 uses H.264 SVC and Cisco uses H.264 AVC. Althougth H.264 SVC is able to talk with H.264 AVC, I think the problem here is signaling.

    I believe that the minor modification in VCS is a code change, so they should realease a new version to be compatible with Lync 2013.

    Best regards

  • Hi,

    Update on that. Out of http://www.cisco.com/en/US/docs/telepresence/endpoint/software/tc6/release_notes/tc_software_release_notes_tc6.pdf. Site 17.

    Lync 2013 integration for point-to-point calls (Requires VCS x8)
    Requires VCS version x8, estimated release August 2013.

    So, what means that. Endpoints are allready supporting H264SVC, VCS Support will come soon and voila we have an Integration - on point to point.... ;-)
