Abstract
A media control system (MCS) enforces media control policies on systems that conform to the relevant protocol specifications (such as SIP and SDP), for example, by interpreting and potentially modifying or destroying the SDP offers embedded in the SIP signaling messages that traverse it. This enables the MCS to exercise control over SIP-associated media sessions without necessarily inserting itself into the media streams themselves. The MCS can enforce media control policies that are based either directly on information that is explicitly contained in SDP message bodies or on secondary information that can be derived from information that is contained in the SDP messages.
