The MCC SDP library provides functions that describe session-level and media-level information for a media session. Session-level information includes the session name, session version, and originator of the session. Media-level information includes the media type, connection information, and codec information.
The MCC SDP library focuses on the parts of SDP applicable to the Offer/Answer model used by SIP. This model is defined by RFC 3264, An Offer/Answer Model with Session Description Protocol (SDP).
