Can't make phone call with UCC API, says User does not exist RRS feed

  • Question

  • Howdy, 

     

    I’m trying to make a phone call from our code using the UCC API following the guidelines here http://msdn.microsoft.com/en-us/library/bb804491.aspx. The problem is the call never makes it through for unknown reasons.

     

    The remote URI I’m using is "sip:14025551212@host.company.com;user=phone";

     

    This is how the UCC API docs say to specify the telephone number. Yet when I look into the uccapi logs I see:

     

    CSeq: 1 INVITE

    Via: SIP/2.0/TCP xx.yy.zz.79:2992;ms-received-port=2992;ms-received-cid=97300

    ms-diagnostics: 1003;reason="User does not exist";source="SRV.host.company.com";TargetUri="14025551212@host.company.com"

    Content-Length: 0


    I’ve tried every uri form I could think of and nothing works. Yet the Microsoft Office Communicator can create a telephone call, yet its log looks nothing like what the test code generates so I don’t know what they are doing different.


    Anyone have some thoughts at what might be wrong here?


    thanx
