   Use Cases and Requirements for SIP-Based Media Recording (SIPREC)

Abstract

   Session recording is a critical requirement in many business
   communications environments, such as call centers and financial
   trading floors.  In some of these environments, all calls must be
   recorded for regulatory and compliance reasons.  In others, calls may
   be recorded for quality control or business analytics.

   Recording is typically performed by sending a copy of the session
   media to the recording devices.  This document specifies requirements
   for extensions to SIP that will manage delivery of RTP media to a
   recording device.  This is being referred to as SIP-based Media
   Recording.

1.  Introduction

   Session recording is a critical operational requirement in many
   businesses, especially where voice is used as a medium for commerce
   and customer support.  A prime example where voice is used for trade
   is the financial industry.  The call recording requirements in this
   industry are quite stringent.  The recorded calls are used for
   dispute resolution and compliance.  Other businesses, such as
   customer support call centers, typically employ call recording for
   quality control or business analytics, with different requirements.

   Depending on the country and its regulatory requirements, financial
   trading floors typically must record all calls.  In contrast, call
   centers typically only record a subset of the calls, and calls must
   not fail, regardless of the availability of the recording device.

   Respecting the privacy rights and wishes of users engaged in a call
   is of paramount importance.  In many jurisdictions, participants have
   a right to know that the session is being recorded or might be
   recorded, and they have a right to opt out, either by terminating the
   call or by demanding that the call not be recorded.  Therefore, this
