Generating call detail records
Abstract
Request and response messages conforming to Media Gateway Control Protocol (MGCP) between media gateways 12 and 16 and a media gateway controller (MGC) 22 are examined to enable them to be correlated. The correlated messages are assembled to produce a call detail record (CDR) describing a voice or data call established over an IP network via the media gateways under the control of the MGC.
