Session Initiation Protocol (SIP) Recording Call Flows
draft-ram-siprec-callflows-03
Abstract
Session recording is a critical requirement in many communications
environments such as call centers and financial trading. In some of
these environments, all calls must be recorded for regulatory,
compliance, and consumer protection reasons. Recording of a session
is typically performed by sending a copy of a media stream to a
recording device. This document lists call flows that has snapshot
of metadata sent from SRC to SRS, the metadata format for which is
described in [I-D.ietf-siprec-metadata] . This is purely an
informational document that is written to support the model defined
in the metadata draft.

Internet-Draft SIP Recording Callflows February 2013
1. Overview
[I-D.ietf-siprec-metadata] document focuses on the Recording metadata
which describes the communication session. The document lists a few
examples and shows the snapshots of metadata sent from SRC to SRS.
For the sake of simplicity the entire SIP [RFC3261] messages are not
shown at various points, instead only a snip of the SIP/SDP message
and the XML snapshot of metadata is shown. This document is
informational and is not normative on any aspect of SIPREC.
