Abstract
When a first SIP INVITE is received a Session Border Controller (SBC) to establish a communication session between communication devices, a second SIP INVITE message is also sent by the SBC to a media recorder without a media line or a media attribute set to inactive. The second SIP INVITE message without the media line or the media attribute set to inactive indicates that there is currently no media associated with the communication session to the media recorder. The SBC receives one of a SIP PUBLISH message or a SIP NOTIFY message that indicates whether to start or stop recording the voice or video communication session. The SBC sends or does not send a media stream of the communication session between the communication devices based on whether the SIP PUBLISH or the SIP NOTIFY indicates whether to start or stop recording the voice or video communication session.
