The Network-Based Recording is a feature of Cisco CUBE. Cisco CUBE acts as a recording client, while MiaRec acts as a recording server. Recording of a media session is done by sending a copy of a media stream to a recording server (media forking). Metadata is the information that is passed by a recording client to the recording server in a SIP session. The recording metadata describes the communication session and its media streams, and also identifies the participants of the call.
