ABSTRACT:
A system for interfacing different types of network communications. In one embodiment, the system includes one or more gateways capable of converting messages from messages that are adapted for a first type of network and/or destination device to messages that are adapted for a second type of network and/or destination device. The second type of network and/or destination device includes a first Voice Over Internet Protocol (VOIP) communications device. A message-analysis module is adapted to employ an address associated with the message to selectively forward the message to one or more of the one or more gateways and/or to a destination device. In a more specific embodiment, the first type of network includes a packet-switched network in communication with the first VOIP phone. The destination device includes a mobile phone in communication with a cellular network. In the specific embodiment, the first type of destination device includes a user option to selectively transition a text-based communications session to a voice-based communications session.
