The invention provides a telecommunication system that allows
communication between a circuit-based wireless telephony network and a
packet-based Internet telephony network without requiring access to the
Public Switched Telephone Network. The system includes a circuit-based
wireless telephony network providing wireless access to the system, a
packet-based Internet telephony network providing Internet telephony
access to the system, and a base station gateway controller for providing
an interface between the wireless telephony network and the Internet
telephony network. The invention further provides methods for
facilitating communication between a first device, the first device being
a packet-based Internet telephony network based device, and a second
device, the second device being a circuit-based wireless telephony
network based device, by facilitating connection of a call from the first
device to the second device, without requiring access to the public
switched telephone network.
