Hello all, I have a question about an SDP offer/answer process:
We assume an SDP offer with a number of codecs is sent to a remote party. Say, PCMU, PCMA, GSM, iLBC and telephone-event are listed in the media attribute. Remote party returns an SDP answer with PCMU, iLBC and telephone-event are listed in the media attribute. In this case, according to the RFC 3264 specification, offerer should be prepared to receive/send either PCMU or iLBC. However it seems to be possible for a buggy remote party to send an SDP answer with G729, PCMU and telephone-event. In this case it turns out to be that the offerer should always examine the received SDP answer doubtfully. So, can we say that all implementations should be prepared to received such nonsense SDP answers? Is it a valid scenario? What should the offerer do when it receives such an answer? Thanks -- M u r at A r t u n, MSc.
