For example, if user A is talking to user B via a proxy P, SDES allows negotiation of keys between A and P or between B and P, but not between A and B. For end-to-end media security you must first establish a trust relationship with the other side.
The SDP is described in the book Service Design, one of the five books that comprises the core of ITIL. The SDP follows the lifecycle of a service from when it is first suggested as a possibility to when it is finally retired. It is the central reference point for all documentation of a service, so it contains many links to other documents.
