1. A telephone device comprising:
- a user interface for receiving, from a user, a telephone number to call, wherein the telephone device is capable of originating a packet-switched call and capable of originating a circuit-switched call, and wherein the telephone device is a device selected from the group consisting of a voice telephone, a fax machine and a dial-up modem, andprogram logic executable to decide, based on the telephone number, whether the telephone device should originate a call to the telephone number as a circuit-switched call or as a packet-switched call,wherein the program logic is executable to determine, based on the telephone number, whether the call is an international call and (i) in response to a determination that the call is an international call, to decide that the telephone device should originate the call as a packet-switched call and (ii) in response to a determination that the call is not an international call, to decide that the telephone device should originate the call as a circuit-switched call,whereby, if the program logic decides that the telephone device should originate the call as a circuit-switched call, then the telephone device originates the call as a circuit-switched call, and, if the program logic decides that the telephone device should originate the call as a packet-switched call, then the telephone device originates the call as a packet-switched call.

Abstract
A method and apparatus are disclosed for causing a telephone device to selectively originate a call as a circuit-switched call or a packet-switched call, depending on the telephone number dialed by a user of the telephone device. By way of example, the telephone device can determine that the dialed telephone number is an international telephone number and can responsively originate the call as a packet-switched call, or the telephone device can determine that the dialed telephone number is not an international telephone number and can responsively originate the call as a circuit-switched call.

2. A method comprising:
-
receiving into a telephone, from a user, a telephone number to call, wherein the telephone is capable of originating a packet-switched call and capable of originating a circuit-switched call; making a determination, based on the telephone number, whether to originate the call as a circuit-switched call or as a packet-switched call; if the telephone number is not an international number, the telephone originating the call as a circuit-switched call, wherein the telephone originating the call as a circuit-switched call comprises sending the telephone number to a serving switch to request the switch to originate the call; and if the telephone number is an international number, the telephone originating the call as a packet-switched call, wherein the telephone originating the call as a packet-switched call comprises acquiring packet-data connectivity and then engaging in packet-based call-setup signaling to set up the call, wherein acquiring packet-data connectivity comprises sending a packet-data origination message over an air interface to a radio access network, and acquiring a Mobile-IP address for communication on a packet-switched network. - View Dependent Claims (3, 4)
