The current specification for the SIP MESSAGE request method indicates that SIP instant messages according to a model similar to that of a text pager, in that each message stands alone. There is no concept of a chat session or a text conference where there is a stream of messages that are grouped into a session. This memo proposes a method of describing MESSAGE sessions by treating the message session just like any other media session described in an SDP body in an INVITE request.
