         Session Initiation Protocol (SIP) Recording Call Flows
                     draft-ietf-siprec-callflows-08

Abstract

   Session recording is a critical requirement in many communications
   environments, such as call centers and financial trading
   organizations.  In some of these environments, all calls must be
   recorded for regulatory, compliance, and consumer protection reasons.
   The recording of a session is typically performed by sending a copy
   of a media stream to a recording device.  This document lists call
   flows with metadata snapshots sent from a Session Recording
   Client(SRC) to a Session Recording Server(SRS).
