Sdp w/o m line is the recommended usage in 3pcc, See RFC3725 sec4.4, if you would like better interop, you'd better not reject this.
If you do need reject, I think 606 Not Acceptable might be better for case1, and your handling for case2 is fine to me. -Rockson -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of karthik karthik Sent: Friday, October 31, 2008 1:36 PM To: [email protected] Subject: [Sip-implementors] sdp with missing m line Hello All, Please let me know the behavior for the below cases. I believe 'm=' line is not mandatory according to rfc 4566 Still It was decided to release the session in our application. case1: Invite is received with SDP, and has no 'm=' line. In case we need to reject such an Invite, what is the most suitable response code? Could we use 415 unsupported media type.? case2: 18x/200 recieved with SDP, and has no 'm=' line. for 18x, send CANCEL for 200, send ACK and BYE. Is this OK?
