Hi, What should be the behavior when SDP is longer than that given in "Content-Length" header?
The RFC 3261 section 18.3 Framing states: If there are additional bytes in the transport packet beyond the end of the body, they MUST be discarded. So this means, SIP parser should discard the data beyond the length given by "Content-Lenght" header. In the below case the call should fail as we wont get enough data from SDP to complete the call as we will drop them. INVITE sip:[EMAIL PROTECTED]:5060 SIP/2.0 Via: SIP/2.0/UDP 10.10.1.209:5061;branch=z9hG4bK-15126-1-0 From: sipp <sip:[EMAIL PROTECTED]:5061>;tag=15126SIPpTag001 To: sut <sip:[EMAIL PROTECTED]:5060> Call-ID: [EMAIL PROTECTED] CSeq: 1 INVITE Contact: sip:[EMAIL PROTECTED]:5061 Max-Forwards: 70 Subject: Performance Test Content-Type: application/sdp *Content-Length: 20* v=0 o=user1 53655765 2353687637 IN IP4 10.253.6.209 s=- c=IN IP4 10.253.6.209 t=0 0 m=audio 6001 RTP/AVP 0 a=rtpmap:0 PCMU/8000 Please suggest what must be the behavior in this case.
