Abstract
The system and method described herein allows for full monitoring and recording of SIP calls by using standard SIP messages. During the call set up between a first SIP device and a second SIP device, information is derived from a first SIP INVITE message from a first SIP device. Information is then derived from a response message from the second SIP device.The monitor/recorder receives one or more SIP INVITE messages to set up a first media stream from the first SIP device and a second media stream from the second SIP device to the monitor/recorder. The monitor/recorder receives the first and/or second media stream. The monitor/recorder then records the first and/or second media stream. In addition, the system and method provide for recording on demand, required recording, and pause-and-resume recording of SIP calls.
