Abstract
Request and response messages conforming to a protocol such as Media Gateway Control Protocol between media gateways and a media gateway controller are examined to enable them to be correlated. The correlated messages are assembled to produce a call detail record describing a voice or data call established over an IP network via the media gateways under the control of the media gateway controller.
