Mediation Server - GatewaySDP: Unrecognized transport profile RRS feed

  • Question

  • Hello,

    Could anyone explain why we get an "unrecognized transport profile" response for this INVITE towards an OCS R2 mediation server?

    My best friend google did not even have a single suggestion for this horrific phrase...

  • Media Attribute "setup:active" in SDP seems to indicate RTP over TCP; This may be the reason for above error message.

  • Hello Johann,

    Thanks for the hint, it might very well be the problem.
    I was using SJphone to test this, but I did not find any settings for RTP transport in that client.
    So I switched to X-lite and now it works.

    The difference in the SIP conversation as I see are that "setup:active" is gone and I have
    a new Media Attribute "alt" which I do not think matters so much.

    Here is the successful setup using X-lite:
