Hi, Prior to RFC 3264, presence of port=0 in the SDP was also used as an indication to put the call on hold. As there is no specific option tag to indicate the support of RFC 3264, how should a party receiving port=0 interpret it? More specifically, should the receiving party delete the resources associated with this stream or just mark this as an inactive stream?
As per RFC 3264, on receipt of port=0 for a media stream all resources associated with this media stream can be released. The slot occupied by this stream can be re-used later to add a new media stream. Can sending a valid port in a previously port zeroed stream reactivate that stream or is it equivalent to a new offer altogether? Regards, Umang Singh | Senior Lead | GlobalLogic Inc.
