Communication device supporting both Internet and public switched telephone network telephony

A voice communication device, coupled to Internet and a public switched telephone network that communicates with a receiving device, the voice communication device comprising:

• a plurality of communication interfaces comprising a public switched telephone network interface and an Internet interface;
• processing circuitry establishes a voice call with the receiving device via a first of the plurality of communication interfaces;
• and
• the processing circuitry hands off the voice call from the first of the plurality of communication interfaces to a second of the plurality of communication interfaces.

A voice communication device that communicates with a remote device, the voice communication device comprising:

• a plurality of communication interfaces, the plurality of communication interfaces comprising an Internet interface and a public switched telephone network interface;
• processing circuitry communicatively coupled with the plurality of communication interfaces;
• the processing circuitry establishes communication with the remote device via an outgoing pathway through a first of the plurality of communication interfaces;
• and
• the processing circuitry switches the outgoing pathway from the first of the plurality of communication interfaces to a second of the plurality of communication interfaces to support a call session.

In a voice communication network comprising a plurality of Internet and public switched telephone network communication pathways, a method for operating a voice communication device that supports both Internet telephony and public switched telephone network telephony, the method comprising:

• setting up a call session with a remote terminal via a first pathway of the plurality of Internet and public switched telephone network communication pathways;
• handing off to a second pathway of the plurality of Internet and public switched telephone network communication pathways to continue the call session;
• and
• at least one of the first pathway and the second pathway comprising an Internet pathway, and at least one of the first pathway and the second pathway comprising a public switched telephone network pathway.
