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.? [SSS] I think the response code 415 is used when UAS doesn't understand the SDP itself. In this case you can reject with 403 Forbidden. case2: 18x/200 recieved with SDP, and has no 'm=' line. for 18x, send CANCEL for 200, send ACK and BYE. Is this OK? [SSS] If 18x has no m= line, I think we can discard and remain silent unless UAC issues CANCEL because chances are there that 200 might have m= line and call may be successful. ( Best Effort Service ) If 200 has no m= line then I think its okay to send BYE as the Call is not meaningful w.r.t. Voice call. If its meaningful in some other service we may not tear it down.
