Abstract: The invention provides a method and a system for enabling communication with a device (206) of a party operating in a hybrid network. The hybrid network combines an Internet-protocol based network (202) and a non-internet-protocol based network (203), wherein the device is an Internet-protocol based device (206). The method includes contacting a first registry being (209) a member in the non-Internet-protocol based network (203) for registering the device in the non-internet-protocol based network. The method also includes contacting a second registry (210) being a member in the Internet-protocol based network (202), for registering the device in the Internet-protocol based network.

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.

Abstract: Apparatus and method for management of optimal voicemail deposit to the voicemail of a currently roaming mobile telephony user during late call forwarding, is located at the user's home network and includes a disconnection unit for disconnecting an international link upon detection of late call forwarding; a triggering unit that ensures that a trigger signal is available for triggering the passing of control of the call to allow direct forwarding of the caller to the voicemail; and a direct forwarding unit that receives the control and carries out the forwarding. Generally the roaming user only generates a single trigger, and this causes difficulties if multiple services need triggering for the same call, such as a prepaid unit and the optimal voicemail deposit. The disclosure teaches methods which when used in combination provide a system that can operate at the home network irrespective of the configuration of the roaming network.
