ABSTRACT:
A method of transporting Call Control related signalling information between a first telecommunications network employing Signalling System No. 7 (SS7) signalling and a second telecommunications network in which Call Control functionality is handled by Media Gateway Controllers and Bearer Control is handled by Media Gateways. The method comprises routing Call Control related signalling data between the signalling network and a Media Gateway Controller through a Media Gateway controlled by said Media Gateway Controller, wherein said Media Gateway implements the lower layers of SS7.
