Abstract
An integrated telephony network includes both a connection-oriented switched telephony (COST) network and a data network telephony (DNT) network, the two networks connected by a dual-ported interactive voice response (IVR) server, the ports adapted to communicate with callers from each network, and a dual-ported translating bridge unit adapted to bi-directionally translate between the data protocols of the connected networks. Each network has at least one service control point (SCP) connected to the IVR, and calls received in either network are routed by connecting callers to the IVR for eliciting information from the caller, and then further routing either in the receiving network or over the translating bridge unit into and through the opposite network according to the information elicited from the caller. An SCP in the DNT network is implemented by connecting a computer-telephony integration (CTD) server to at least one IP router in the DNT. The DNT network may be the Internet and the COST network can be any publicly-switched telephone network.
