System for interconnecting packet-switched and circuit-switched voice communications
First Claim
1. A method of establishing voice communication between a phone connected to a circuit-switched network and one or more hosts connected to a packet-switched network, comprising:
- receiving, at a gateway connected between the circuit-switched network and the packet-switched network, a call request from the phone;
sending, from the gateway, a first audio message to the phone requesting a destination address on the packet-switched network of a host of the one or more hosts;
receiving the destination address of the host from the phone responsive to the first audio message;
establishing a call comprising two-way voice communication, via the circuit-switched network and the packet-switched network, between the phone and the host based on the destination address of the host;
sending, from the gateway, a second audio message to the phone requesting a user name of a called party associated with the host; and
receiving the user name of the called party from the phone responsive to the second audio message.

Abstract
A system and method for establishing voice communication between a packet-switched network and a circuit-switched network includes a network interface unit for coupling to the packet-switched network, a phone interface unit for coupling to the circuit-switched network and a gateway processor coupled to the network interface unit and to the phone interface unit. In response to a call request, a packet-switched network connection is established between the gateway processor and a first station in the packet-switched network, and a circuit-switched network-connection is established between the gateway processor and a second station in the circuit-switched network. Incoming voice data packets received from the first station are converted to outgoing voice signals, which are transmitted over the circuit-switched network connection to the second station. Incoming voice signals received from the second station are converted to outgoing voice data packets, which are transmitted over the packet-switched network connection to the first station. A conference call may be established among three or more conference call participants.

9. A system for establishing voice communication between a phone connected to a circuit-switched network and one or more hosts connected to a packet-switched network, comprising:
-
a network interface unit coupled to the packet-switched network;
a phone interface unit coupled to the circuit-switched network; and
a gateway processor coupled to the network interface unit and the phone interface unit and configured, in conjunction with the network interface unit and the phone interface unit, to;
receive a call request from a phone coupled to the circuit-switched network, send at least one audio message to the phone requesting a destination Internet Protocol (IP) address on the packet-switched network of a host of the one or more hosts, and a user name of a called party associated with the host, receive the destination IP address of the host and the user name from the phone, and establish a call comprising two-way voice communication, via the circuit-switched network and the packet-switched network, between the phone and the host based on the destination IP address of the host and the user name of the called party.

10. A method of establishing voice communication between a phone connected to a circuit-switched network and a plurality of hosts connected to a packet-switched network, comprising:
-
receiving, at a gateway connected between the circuit-switched network and the packet-switched network, a call request from the phone;
sending from the gateway, a first audio message to the phone requesting destination addresses on the packet-switched network associated with each of the plurality of hosts;
receiving the destination addresses of each of the plurality of hosts from the phone responsive to the first audio message;
establishing a conference call comprising two-way voice communication, via the circuit-switched network and the packet-switched network, between the phone and each of the plurality of hosts based on the destination addresses of the plurality of hosts;
sending, from the gateway, a second audio message to die phone requesting user names of called parties associated with each of the plurality of hosts; and
receiving the user names of the called parties from the phone responsive to the second audio message. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
