  • Least cost router
    Patent number: 6141411
    Abstract: A telecommunications call routing device provides call routing based on digits received at the device from an exchange. The routing device has the facility to route by one of a plurality of networks, including both private networks and public networks, and to force calls to be placed over a private network if a route is available. Early reconnection of calls is also possible by monitoring call progress tones, measuring the pauses between dialed digits and reconnecting the exchange to a network or PBX as soon as the routing decision is made.
