Patent ID: 7277424

Claim:
A first computerized device configured to place a telephone call via a circuit switched telephone network to a second computerized device, comprising: a telephone subscriber interface to be coupled to the circuit switched telephone network; a computer readable medium that stores instructions; a set of digital circuits that includes a processor, wherein the processor executes the instructions to enable the set of digital circuits to cooperatively function to: cause a set of telephone dialing digits to be coupled via the telephone subscriber interface to the circuit switched telephone network to cause a circuit-switched telephone call to be placed to the second computerized device, wherein a circuit-switched telephone connection is established to couple into communication the first and second computerized devices; cause a data packet to be sent to the second computerized device by coupling from the first computerized device, an indication of the telephone dialing digits used to establish the circuit-switched telephone connection, to a remote server that determines an address of the second computerized device based upon the indication of the dialing digits, wherein the address is used to set up a packet switched data connection between the first and second computerized devices; and cause data to be communicated from the first computerized device to the second computerized device utilizing the packet switched data connection; wherein the packet switched data connection is established via a packet switched transmission path that is different than a circuit-switched transmission path over which the circuit-switched telephone connection is established, and wherein at least one of the computerized devices is a user computerized device with a user interface, and the packet switched data connection is used to carry application layer data for presentation to a user via the user interface while the circuit-switched telephone call is in progress between the first computerized device and the second computerized device.
