Abstract
A service control point (SCP) (140) associated with a public-switched telephone network (PSTN) (110) includes a service logic module (210-N+1) and a network interface (215). The service logic module (210-N+1) enables the service control point (SCP) (140) to establish a connection with an Internet Protocol (IP) application server (120) via a transmission control protocol/Internet protocol (TCP/IP) network (105). The network interface (215) communicates via the connection to integrate telephony services between the PSTN (110) and the TCP/IP network (105).
