ABSTRACT:
Methods, systems, and apparatus are provided to enable access to mobile and voice over IP (VoIP) telephone networks with a mobile handset. A VoIP gateway for the VoIP telephone network is provided. A cable modem allows communication between the handset and the VoIP telephone network via the VoIP gateway. A local network connects the handset to the VoIP gateway. The mobile handset determines whether it is within range of the local network. If the handset is within the range of the local network, data traffic may be routed to and from the handset via the VoIP telephone network. If the handset is outside of the range of the local network, data traffic may be routed to and from the handset via the mobile telephone network. The data traffic may comprise telephony data traffic and/or Internet protocol (IP) data traffic.
