摘要： A communications network resource conservation system is provided for that conserves network bandwidth and improves voice quality. The method and apparatus permit users of H.323 terminal devices to talk to each other directly over the Internet thereby eliminating the need to use the resources of a telephone switch and a Public Switched Telephone Network (PSTN). Communication between users is established directly via packet network. In one embodiment, a voice path between users is directly established without routing the voice through a PSTN as for a typical telephone call and yet get supplementary services from the PSTN switch. The telephone call will be set up through the telephone switch and the PSTN as for a normal call, but, the voice path will be Intraswitched directly between the calling party and the called party via their packet network. In another embodiment, the invention provides a way to revert an Intraswitched call through the telephone switch automatically when needed to invoke supplemental features of telephony service.

摘要： A method and apparatus establishes through the public switch telephone network, a multimedia communications session between first and second telecommunications infrastructure. Each infrastructure is located on a separate private data network and comprises logic to automatically establish an integrated voice and data session initiated by a single telephone call from one infrastructure to the other.
摘要翻译：方法和装置通过公共交换电话网建立第一和第二电信基础设施之间的多媒体通信会话。每个基础设施位于单独的专用数据网络上，并且包括逻辑，以自动建立由单个电话呼叫从一个基础设施发起到另一个的集成语音和数据会话。

摘要： Method and apparatus for transferring a call leg in a telecommunication network and releasing it to free up resources, while allowing retrieval at a later time under specified conditions. Message extensions are provided for interfaces used between service nodes and host switches in a telecommunication networks. The invention is appropriate for use in an integrated services digital network (ISDN), in an internet protocol (IP) telephony network, or in any other type of telecommunication network. The service node sends a transfer request and retrieval conditions -to the switch. The switch stores the conditions and transfers the channel with the appropriate call leg, but can retrieve the call leg when one of the conditions is met.
