Abstract
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.
