摘要： Techniques for determination of endpoint Internet Protocol (IP) address assignment in an Internet telephony system are disclosed. In conjunction with the establishment of a voice path between an endpoint and a gatekeeper in the Internet telephony system, a virtual address assigned to the endpoint in a network address translation operation is determined. The virtual address is then communicated to the endpoint as part of or otherwise in conjunction with a registration process prior to establishment of the voice path such that the registration process can complete successfully despite the network address translation operation. Advantageously, the invention overcomes problems associated with voice path registration failures resulting from network address translation in a router, virtual private network (VPN) gateway or other similar network address translation device.

摘要： A switching system (100) inserts H.320 multi-media protocol-terminating resources (156) into an existing call dynamically, only when the resources are needed, and also removes the resources from an ongoing call dynamically, when the resources are no longer needed, whereby the switching system can provide call features such as hold, conference, disconnect, drop, and transfer, to an H.320 multi-media call and can do so spontaneously, whenever desired during the call, without tying up the resources for the duration of the call even when they are not needed. To extend these capabilities to both single-channel and multi-channel multi-media ISDN BRI calls, the switching system associates a plurality of calls that constitute the individual channels of a multi-channel call and treats the associated calls identically and in unison for purposes of insertion and removal of resources and the providing of features.
摘要翻译：交换系统（100）仅当需要资源时才将H.320多媒体协议终止资源（156）插入到现有呼叫中，并且当资源不再是动态地从正在进行的呼叫中移除资源因此交换系统可以向H.320多媒体呼叫提供诸如保持，会议，断开，丢弃和传送的呼叫特征，并且可以在呼叫期间根据需要自发地进行，而不需要为了呼叫的持续时间，即使不需要。为了将这些能力扩展到单信道和多信道多媒体ISDN BRI呼叫，交换系统将构成多信道呼叫的各个信道的多个呼叫相关联，并且为了目的而一致地对待相关呼叫插入和删除资源和提供功能。
