1. A voice-over-internet-protocol (VOIP)/public-switching-telephone-network (PSTN) control system, comprising:
- a VOIP/PSTN interface comprising;
a first port configured to receive and transmit VOIP-compatible communication signals;
a second port configured to receive and transmit PSTN-compatible communication signals;
a VOIP client module configured to convert received VOIP-compatible communication signals and to convert PSTN-compatible communication signals; and
a communication module configured to generate control signals to control coupling of a premises phone network to a PSTN provider network; and
a network-interface-unit-controller configured to selectively couple the premises phone network to the PSTN provider network in response to the control signals.

Abstract
A VOIP/PSTN system is configured to allow analog telephones connected to an existing analog premises telephone network to place and receive VOIP and PSTN telephone calls through the analog premises telephone network. In one embodiment, the system is configured to selectively disconnect the premises telephone network from the PSTN.
