ABSTRACT:
A system and method for providing telephony services, such as caller ID, voice mail, selective call forwarding, and the like, to a remote subscriber, typically located outside the providers regional territory. The system can include customer premise equipment (CPE) selectively connectable to a remote central office (CO), a packet-switched network gateway, such as an Internet telephony gateway (ITG), for remotely communicating service requests to a local service node. The local service node can be located within the service provider's territory and returns telephony service responses via the packet-switched network gateway to the remote CO, and ultimately the remote CPE.
