    Sip Stack sends a 500 Internal server error for invite!?

    Hi Group,
    Currently am facing the following issue , anyone who has insight in SIP can please guide me.
    I have text based SIP application running on my mobile when i try to invite this client with internet available Sip client which by default sends a Invite with audio stream in SDP, where as what my application needs is only Text stream in SDP.pls find the logs

    Call Flow
    ---------> Invite Sent

    Request-Line: INVITE sip:nokia1@ SIP/2.0
    CSeq: 1 INVITE
    From: "Sakshi" <sakshi@>tag1224761353978
    To: <sip:nokia1@ >
    via: SIP/2.0/UDP;branch=z9hg4bk1224761353978

    <---------- 500 Internal Server Error

    Status-Line: SIP/2.0 500 Srever Internal Error
    via :SIP/2.0/UDP
    To: <sip:nokia1@ >;tag=1224761353978
    From:"Sakshi" <sakshi@>tag=1224761353978
    Call-ID :62a5c14900ec8d982a366e742d90133@
    CSeq: 1 INVITE

    Why do think my sip client sends a 500 error? should it just not reject the audio streams ,and accept the text streams?

    I think that the error happens in your sip server.maybe you can check your sip settings.
