    480 Temporarily Not Available

    Hi,

    I set the mentioned below capabilities for Media type audio but still having a problem "480 Temporarily Not Available" please give me any clue,Another user is not able to receive an INVITE request.

    _LIT8(KCapabilities,
    "<SIP_CLIENT ALLOW_STARTING=\"YES\">\
    <SIP_HEADERS>\
    <ACCEPT_CONTACT value=\"*;mobility=mobile;media=audio\" />\
    <ALLOW_EVENTS value=\"presence\" />\
    <ACCEPT value=\"audio/basic\" />\
    <ACCEPT value=\"application/sdp\" /> \
    </SIP_HEADERS>\
    <SDP_LINES>\
    <LINE name=\"m\" value=\"audio 30000 RTP/AVP 8\" />\
    </SDP_LINES>\
    </SIP_CLIENT>" );

    Little modification is done in creating CSdpMediaField.Like i'm setting EMediaAudio and EProtocolRtpAvp as a media type and protocol.so the INVITE request is looking like that...

    INVITE sip:5000@10.1.7.118 SIP/2.0
    Via: SIP/2.0/UDP 10.1.7.111;branch=z9hG4bKbc96991ff4d4e6f7cde5defec3d84efa

    To: <sip:5000@10.1.7.111>
    Contact: <sip:5001@10.1.7.120>
    CSeq: 1114 INVITE
    Call-ID: r3-xrc0AoIfvfbx7rJUBvv28Xz8WqC
    Max-Forwards: 69
    Content-Type: application/sdp
    Accept: application/sdp
    Content-Length: 141

    v=0
    o=5000 523427878 2890844532 IN IP4 127.0.0.1
    s=SipSession
    c=IN IP4 127.0.0.1
    t=0 0
    m=audio 30000 RTP/AVP 8
    a=rtpmap:8 PCMA/8000/1

    "480 Temporarily Not Available" is received in response.Any clue on that would be appreciable.Alot of threads are on forum but no boday post the solution of it and this is a big road block for developing RTP part of VOIP application.

    Thanks in advance,

    Haroon
