Hi, as RFC 3264 says answer should contain adjectly same number of line present in offer, if INVITE contains SDP without m= line then answer in 200 ok should also contain SDP without " m=" lines hence ACK will also not contain "m=" lines, and call will established without media, so my question is 1.how caller should respond for this, does caller need to reject the call with bye/cancel ? 2. or callee should have responded with 415 unsupported media. 3. Isn't it mean caller wants to put callee on HOLD in initial stage ?
