Hi there, My proxy is forwarding a SIP MESSAGE to the end user, which has the following contents:
MESSAGE sip:[email protected] SIP/2.0 Via: SIP/2.0/UDP 192.168.100.94;branch=z9hG4bK.9Uv96pr9jv6j852j3HD2aSSUFe Via: SIP/2.0/UDP 88.30.142.86;branch=z9hG4bKpl9r8q Max-Forwards: 70 From: Shell <sip:[email protected]>;tag=bq0lfn To: <sip:[email protected]>;tag=bq0lfn Call-ID: [email protected] CSeq: 109629559 MESSAGE Supported: sec-agree Content-Length: 0 P-Preferred-Identity: Shell <sip:[email protected]> And the UAC is replying with error code 481: SIP/2.0 481 Call/Transaction Does Not Exist Via: SIP/2.0/UDP 192.168.100.94;branch=z9hG4bK.9Uv96pr9jv6j852j3HD2aSSUFe;rport=5060;received=217.116.77.150,SIP/2.0/UDP 88.30.142.86;branch=z9hG4bKpl9r8q To: <sip:[email protected]>;tag=bq0lfn From: Shell <sip:[email protected]>;tag=bq0lfn Call-ID: [email protected] CSeq: 109629559 MESSAGE Content-Length: 0 Is that somehow possible? a SIP MESSAGE may be sent out of any SIP session, so why is the UAC checking for that specific Call-ID and rejecting the SIP MESSAGE? Maybe I'm missing something...
