Patent ID: 8532090

Claim:
An end-user device, comprising: a telephony port in the end-user device for connecting to a local PSTN using a single line Foreign Exchange-Office (FXO) interface; an audio interface in the end-user device configured and arranged to generate audible sounds in response to receiving audio communication data; a packet-based interface in the end-user device for connecting to a packet-based network; and a routing controller, configured and arranged in the end-user device, for receiving, from the packet-based interface, audio communication data that includes an indication of a destination device, providing, in response to determining that the end-user device corresponds to the destination device, the audio communication data to the audio interface, in response to determining that the destination device corresponds to a destination device other than the end user device, dialing the destination device using the telephony port and the single line; communicating the audio communication data to the telephony port and over the single line FXO interface, and detecting an outgoing call from the audio interface and, in response thereto, applying a rule that dictates priority of the audio interface over audio communication data from the packet-based interface for connecting the outgoing call over the single line FXO interface.
