SDP has been extended with a capability negotiation mechanism framework that allows the endpoints to negotiate transport protocols and attributes. This framework has been extended with a Media capabilities negotiation mechanism that allows endpoints to negotiate additional media-related capabilities. This negotiation is embedded into the widely-used SDP offer/answer procedures. This memo extends the SDP capability negotiation framework to allow endpoints to negotiate a number of miscellaneous SDP capabilities. In particular, this memo provides a mechanism to negotiate media titles ("i=" line for each media), connection data ("c=" line), and media bandwidth ("b=" line).
