Patent ID: 7299049

Claim:
A device comprising: a physical component for wireless communication; and a processor coupled with the physical component, in which the processor is adapted to establish an original leg of a telephone call connection with a networking endpoint over one of a circuit-switched network or a packet-switched network, where the networking endpoint is directly coupled to both the circuit-switched network and the packet-switched network; transfer data of a voice conversation between the original leg and a voice channel that terminates in one of a speaker and a microphone pursuant to the telephone call connection; exchange a handoff signal with the networking endpoint over the original leg of the telephone call connection after transferring data of the voice conversation over the original leg to the networking endpoint; establish an alternate leg of the telephone call connection with the networking endpoint over the other one of the circuit-switched network or the packet-switched network while the original leg is still established responsive to the handoff signal and transfer data of the voice conversation between the voice channel and the alternate leg pursuant to the telephone call connection.
