Abstract

A system and method for processing a call comprises a signaling interface to receive and process call signaling and transmit call signaling between a call processor and communication devices such as a local number portability service control point. A call processor processes call signaling to determine call connections. A local service control point (local SCP) provides information such as, for example, for N00 routing and virtual private network (VPN) routing. The local SCP resides with the call processor on a single platform so that they are connected, for example, through a backplane or bus architecture. In this configuration, transaction capabilities application part messages do not have to be transmitted between the signaling interface and the local SCP. Instead, direct communication can occur through control messages transmitted between the local SCP and the call processor thereby realizing increased speed and processing efficiency. Because the local SCP resides with the call processor, two remote dips to an SCP is not necessary.
