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 the SRS.

    The SRC and SRS act as SIP User Agents (UAs) user agents 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  Spacevars0product 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)UDP by default. The SBC also supports SIPREC INVITE to the SRS over Transmission Control Protocol (TCP)TCP or TLS.
    • 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.

    1Siprec - Start Recording Parameters

    Parameter

    Description

    GcidGCID

    Specifies the GCID of the call to start recording.

    Call Leg

    Call leg associated with this recording session. The options are:

    • Egress
    • Ingress (default)
    Num of Of StreamsSpecifies the number (1 or 2) of simultaneous streaming to different SRS IP addresses. By default, the value is 1.
    Srs IP AddressSpecifies the IP address of the Recording ServerSRS.
    Srs PortSpecifies the UDP Port of the Recording ServerSRS.
    Srs IP Address2Address2

    Specifies the IP address of the secondary recording server to which the media stream is forked.

    NOTE: This parameter is mandatory if the parameter Num Of Streams is set to 2.

    Srs Port2Port2

    Specifies the IP port of the secondary recording server to which the media stream is forked.

    NOTE: This parameter is mandatory if the parameter Num Of Streams is set to 2.

    Trunk GroupSpecifies the name of the SIPREC trunk group associated with this recording session.
    Transport

    Select the transport protocol over which you want to send the SIPREC INVITE. The options are:

    • UDP (default)
    • TLS
    • TCP
    Trunk Group2

    Specifies the name (maximum 24 characters) of the SIPREC trunk group towards second SRS IP with which the calls have to be recorded.

    NOTE: This parameter is mandatory if the parameter Num Of Streams is set to 2.

    Transport2

    Specifies the type of transport to be used for recording session on the secondary SRS IP. The options are:

    • UDP (default)
    • TLS
    • TCP

    NOTE: This parameter is mandatory if the parameter Num Of Streams is set to 2.

    Make the required changes and click startRecord on the pop-up window to initiate the SIP-based session recording. Click the "Command Name" button to implement the option. The result of the action is displayed.

    titleNote

    If the parameter Num of Streams is set to "1", and secondary SRS details are provided for the parameters Srs Ip IP Address2, Srs Port2, and Trunk Group2, then the information about the secondary SRS information is used for redundancy when if the  primary SRS goes down.

     

    Info
    titleNote:

    The SBC supports executing the startRecord command twice: once for the ingress call-leg and once for the egress call-leg, to establish up to two streams in both directions simultaneously to achieve quad-recording.

    To stop recording

    Description

    GCID

    Specifies the GCID of the call to stop recording.

    Recorder AddressSpecifies the IP address of the recorder on which to stop the recording of a GCID value.
