SIP extensions for SIP recording

A set of SIP extensions have been defined to allow SIP entities to distinguish between a Recording Session and a Communication Session and so that a SIP UA can know if a session is being recorded - see Internet draft: “SIP Call Control - Recording Extensions” [Johnston 2010] - for the definitions of the new feature tags: src (session recording clients indicates this session is for the purposes of a recording session), srs (used by the session recording server), and recorded (to indicate that some or all of the media session is being recorded)
