Service exchange in a VoIP to telephony bridging network
First Claim
1. In an infrastructure supporting both Voice over Internet Protocol (VoIP) telephony via the Internet and Public Switched Telephone Network (PSTN) telephony via the PSTN, a system comprising:
- a plurality of client telephony bridging devices communicatively coupled to both the Internet and to the PSTN and operable to bridge calls between the Internet and the PSTN;
server processing circuitry communicatively coupled to the plurality of client telephony bridging devices and operable to enact access rules for the plurality of client telephony bridging devices and for a plurality of subscribers, the server operable to;
receive a voice call setup request from a calling voice terminal via the Internet, the voice call setup request identifying a subscriber;
obtain access rules for the subscriber; and
based upon the access rules for the subscriber and the access rules for the plurality of client telephony bridging devices, select a servicing telephony bridging device from the plurality of client telephony bridging devices; and
the servicing client telephony bridging device operable to bridge an incoming call for the calling voice terminal between the Internet and the PSTN.

Abstract
An infrastructure that supports both Voice over Internet Protocol (VoIP) telephony via the Internet and Public Switched Telephone Network (PSTN) telephony via the PSTN. A plurality of client telephony bridging devices communicatively couple to both the Internet and to the PSTN and are operable to bridge calls between the Internet and the PSTN. Server processing circuitry communicatively couples to the plurality of client telephony bridging devices and is operable to receive a voice call setup request from a calling voice terminal via the Internet or PSTN. The server processing circuitry is operable to select a servicing telephony bridging device from the plurality of client telephony bridging devices. The servicing client telephony bridging device is operable to bridge an incoming call for the calling voice terminal between the Internet and the PSTN.
