Abstract
A method, system and gateway for control of calls unanswered by a roaming user roaming on a roaming network, comprises monitoring outward bound calls to roaming users, monitoring subsequent inward forwarding of those calls terminated without answering at said roaming users, and matching between the outward bound and inward forwarding. Matching confers control of processing of the terminated call in two ways. One is that it allows call details, typically lost over International networks, to be obtained regarding the terminated call. Secondly, it allows the originating call to be connected directly to the voicemail or other forwarding destination without involving any International connections.
