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.
