Re: [Sipp-users] Scenario Registers but will not process call.

Nevermind, I see that you have the full 415 message in the e-mail. It doesn't give much additional information. The case may be that it is failing with 415 even before it tries to do the authentication. Add a CRLF in your first INVITE after ptime:20. See if that gets you the 100 message and then the 407.

The '415 Unsupported Media Type' is usually caused by the Media Parameters in the SDP. My theory is that the authentication is happening successfully, the next step is to negotiate the media and that is where it is failing. You can put the [field1] in the same place as the REGISTER (after Content-Type, before Content-Length). Also, are you collecting the messages using the -trace_msg? The full 415 message may give you additional information on why its failing with Unsupported Media Type.

    Tim,

    The Unsupported Media Type may be caused due to the fact that it
    cannot read the rtpmap attribute for PCMU. Try adding a CRLF
    after the last line of your SDP in the second INVITE. Your first
    INVITE and second INVITE have differences in the SDP (first one
    includes support for RFC 2833 payload 101). You should leave that
    in the second INVITE as well.

    Your second INVITE should look as follows:
