First Claim
1. A communication device, comprising:
- a computer interface, for coupling to a computer, which is connected to communicate over a packet-switched network;
a secure memory interface, for coupling to a secure memory containing subscriber identification data belonging to a subscriber; and
a program memory, containing an executable application program, which is configured to be read by the computer via the computer interface and upon execution by the computer, causes the computer to communicate via the packet-switched network with a telephony gateway so as to register the subscriber with the gateway using the subscriber identification data and to communicate, under control of a user of the computer, via the gateway with a telephone network.

Abstract
A communication device (22) includes a computer interface (84), for coupling to a computer (26), which is connected to communicate over a packet-switched network (28). A secure memory interface (82) in the device is coupled to a secure memory (64) containing subscriber identification data belonging to a subscriber. A program memory (88) in the device contains an executable application program, which is configured to be read by the computer via the computer interface and upon execution by the computer, causes the computer to communicate via the packet-switched network with a telephony gateway (34) so as to register the subscriber with the gateway using the subscriber identification data and to communicate, under control of a user of the computer, via the gateway with a telephone network (38).
