Can not place a T.38 FAX call to Mediation Server RRS feed

  • Question

  • Hi,
       When I try to place a T.38 FAX call to Mediation Server, I get the following error from mediation server.

    SIP/2.0 488 Invalid SDP: Mismatched media name

    The SIP message which caused this had the following SDP payload (relevent to T38 signaling):
    m=image 16704 udptl t38

    a=T38FaxVersion:0

    a=T38MaxBitRate:14400

    a=T38FaxRateManagement:transferredTCF

    a=T38FaxUdpEC:t38UDPRedundancy
    Questions:
    1. Does mediation server support T.38 fax?
    2. If yes, what types of SDP signaling does it expect?
        RFC3362 (udptl t38) or RFC4612 (audio t38) or something else?

  • It's by design. Mediation Server doesn't support T.38.

  • Would this ability be available in the release build of OCS 2007? I know other MS products like UMS support receiving T.38 FAX.
