Abstract: A system and method for electronic communications; more specifically, a system and method for transmitting real-time or non-real-time voice and facsimile electronic data across both circuit-switched and packet-switched networks. The system may include a gatekeeper server capable of communicating with a system subscriber across a packet-switched network and a network node capable of communicatively interconnecting a circuit-switched network, such as the Public Switched Telephone Network (PSTN), and a packet-switched network utilizing the Internet Protocol for transmission. If a subscriber is not available to receive an electronic communication at his primary telephone number or IP address, the system may be capable of re-directing the communication to additional telephone numbers or IP addresses across either the circuit-switched or packet-switched networks, according to the subscriber's preferences.
