    Abstract: A relay switching circuit to route outgoing telephone calls between a VoIP and a landline and with a surge voltage protection includes a first relay, a second relay, a first control circuit, and a second control circuit. The first relay connects with a foreign exchange station (FXS) port and an FXS circuit to control a connection between the FXS port and the FXS circuit. The second relay connects with the first relay and a foreign exchange office (FXO) port to control a connection between the first relay and the FXO port. The first control circuit connects with a controller to control the first relay. The second control circuit connects with the controller to control the second relay.
