SIP-based Media Recording

The device can record SIP-based media (call sessions) traversing it. This applies only to
SBC calls. This support is in accordance with the Session Recording Protocol (siprec),
which describes architectures for deploying session recording solutions and specifies
requirements for extensions to SIP that will manage delivery of RTP media to a recording
device. The siprec protocol is based on RFC 6341 (Use Cases and Requirements for SIP-
Based Media Recording), Session Recording Protocol (draft-ietf-siprec-protocol-02), and
Architecture (draft-ietf-siprec-architecture-03).
Notes:
•
The SIP-based Media Recording feature is available only if the device is installed
with a Software License Key that includes this feature. For installing a Software
License Key, see ''Software License Key'' on page 598. The Software License Key
also specifies the maximum number of supported SIP recording sessions.
•
For the maximum number of concurrent sessions that the device can record,
contact your AudioCodes sales representative.
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.
The siprec protocol specifies the use of SIP, SDP, and RTP to establish a Recording
Session (RS) from the Session Recording Client (SRC), which is on the path of the
Communication Session (CS), to a Session Recording Server (SRS) at the recording
equipment. The device functions as the SRC, sending recording sessions to a third-party
SRS, as shown in the figure below.
