This document defines a mechanism by which two entities can make use of the
Session Description Protocol (SDP) to arrive at a common view of a multimedia session between them.
In the model, one participant offers the other a description of the desired session
from their perspective, and the other participant answers with the desired session from their perspective.
This offer/answer model is most useful in unicast sessions where information from both participants is
needed for the complete view of the session. The offer/answer model is used by protocols
like the Session Initiation Protocol (SIP). [STANDARDS-TRACK]
