SIP Recording (siprec) ---------------------- Charter Last Modified: 2011-02-04 Current Status: Active Working Group Chair(s): Brian Rosen John Elwell Real-time Applications and Infrastructure Area Director(s): Gonzalo Camarillo Robert Sparks Real-time Applications and Infrastructure Area Advisor: Gonzalo Camarillo Technical Advisor(s): Peter Saint-Andre Mailing Lists: General Discussion:siprec@ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/siprec Archive: http://www.ietf.org/mail-archive/web/siprec/current/maillist.html Description of Working Group: The Session Recording Protocol (SIPREC) working group is chartered to define a SIP-based protocol for controlling a session (media) recorder. 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, business analytics, or consumer protection. Recording is typically done by sending a copy of the media to the recording devices. The working group will determine requirements and produce a specification for a protocol that will manage delivery of media from an end-point that originates media, or that has access to it, to a recording device. PBX and recording vendors today implement proprietary, incompatible mechanisms to facilitate recording. A standard protocol will reduce the complexity and cost of providing such recording services. The Session Recording problem presents certain unique requirements that are not addressed in the current SIP protocol specification. These include requirements such as the need for a distinction between the session that is being recorded versus the session that has been established for recording. Privacy and security of conversations are significant concerns. The working group will make sure that any protocol specified addresses these concerns and includes mechanisms to alert users to the fact that a session they are participating in is being recorded. The working group must take care that the session recording requirements and protocol does not conflict with the IETF statement on wiretapping contained in RFC 2804. The SIPREC Working Group will thoroughly identify use cases, provide example system architectures and deployment scenarios, and define requirements. The scope of the activity includes: * Recorder Control * Session metadata content and format * Security mechanisms, including transport and media encryption * Privacy concerns, including end-user notification * Negotiation of recording media streams The group will define these issues and rationalize with IETF standards and practices. This includes encryption, NAT traversal, operations and manageability, SIP-enabled firewalls, authorization, and security. The group will produce: * Updated Requirements, Use Cases, Architecture draft * Specification for Session Recording Protocol Goals and Milestones: Done Use Cases and Requirements to IESG as Informational RFC Aug 2011 Architecture to IESG as Informational RFC Dec 2011 Submit Metadata model and format to IESG as Proposed Standard RFC Jan 2012 Submit protocol draft to IESG as Proposed Standard RFC Internet-Drafts: Posted Revised I-D Title ------ ------- -------------------------------------------- May 2010 May 2011 Use Cases and Requirements for SIP-based Media Recording (SIPREC) Jun 2010 Apr 2011 An Architecture for Media Recording using the Session Initiation Protocol Apr 2011 Apr 2011 Session Initiation Protocol (SIP) Recording Metadata Request For Comments: None to date.
