Abstract
A localized digital telephone network may automatically contact a centralized server to identify telephone numbers that connect the local network to a public switched telephone network (PSTN). The server may be a remote identification server that receives calls from local networks, and informs the local networks of the telephone numbers being used by the local networks. The server may capture caller-ID information of the incoming calls, and may return the calls with the captured information encoded in caller-ID signals of the return calls. A method for automated detection may include acts in which a local network generates an outgoing call to a server on a communications port, and then detects an incoming call from the server on the communications port. The local network may determine a caller identifier from the incoming call, and may map the caller identifier to the communications port.
