Session Recording Protocol
draft-ietf-siprec-protocol-10
Abstract
This document specifies the use of the Session Initiation Protocol
(SIP), the Session Description Protocol (SDP), and the Real Time
Protocol (RTP) for delivering real-time media and metadata from a
Communication Session (CS) to a recording device. The Session
Recording Protocol specifies the use of SIP, SDP, and RTP to
establish a Recording Session (RS) between the Session Recording
Client (SRC), which is on the path of the CS, and a Session Recording
Server (SRS) at the recording device.
