This section describes configuration for various supported services.
18.1 SIP-based Media Recording
The device can record SIP-based media call sessions traversing it for Gateway and SBC
calls. The media recording 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).
Warning for Deployments in France: The device supports SIP-based Media
Recording (SIPRec) according to RFC 6341. As such, you must adhere to the
Commission Nationale Informatique et Libert
י
’s (CNIL) directive
(http://www.cnil.fr/english/data-protection/rights-and-obligations/) and be aware that
article R226-15 applies penalties to the malicious interception, diversion, use or
disclosure of correspondence sent, transmitted or received by means of
telecommunication, or the setting up of a device designed to produce such
interceptions.
Note:
•
The SIP-based Media Recording feature is available only if the device is installed
with a License Key that includes this feature. The License Key specifies the
maximum number of supported SIP recording sessions. For installing a License
Key, see License Key on page 797.
•
The device supports up to 50 concurrent SIPRec sessions that can be recorded.
This capacity assumes that there are no other concurrent, regular (non-SIPRec)
voice sessions.
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.
