The SIPREC protocol defines the interaction between a Session Recording Client (SRC) and a Session Recording Server (SRS), and controls the recording of media transmitted in the context of a communications session (CS) between multiple user agents.

The 

Spacevars
0series4
supports the following SIP recording (SIPREC) interfaces:

  • SIPREC SIP-based session recording
  • Call monitoring MCT
  • NICE session recording

A basic call, or communication session (CS), is established between SIP phone 1 and SIP phone 2 through the

Spacevars
0product
. The 
Spacevars
0product
establishes a Recording session (RS) for the CS based on configuration towards SRS.

The SRC and SRS act as SIP User Agents (UAs) whereby the SRC provides additional information (called metadata) to the SRS recording session to describe the communication sessions, participants and media streams to facilitate archival and retrieval of the recorded information.

The 

Spacevars
0product
determines if a call is configured to be recorded, and if SIPREC is to be used.

Info
titleNote

The SIPREC feature is controlled by a system-wide SBC license (SBC-SIPREC). If the license is not available, any SIPREC recording returned by a PSX is ignored.

Info
titleNote
  • For SIPREC SIP-based session recording, the SBC as SRC sends the INVITE to the SRS over User Datagram Protocol (UDP). The SBC also supports SIPREC INVITE to the SRS over Transmission Control Protocol (TCP).
  • To support SIPREC INVITE over TCP, the Sip Sig Port, which is configured in the zone for SIPREC, must have Transport Protocols Allowed as sip-tcp.
