Session Recording Protocol
Abstract
This document specifies the use of the Session Initiation Protocol
(SIP), the Session Description Protocol (SDP), and the Real-time
Transport 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. This document considers only
active recording, where the SRC purposefully streams media to an SRS
and all participating user agents (UAs) are notified of the
recording. Passive recording, where a recording device detects media
directly from the network (e.g., using port-mirroring techniques), is
outside the scope of this document. In addition, lawful intercept is
outside the scope of this document.
