Patent abstract
A VoIP adapter module for a VoIP phone system switches the phone connection from a broadband connection to a wired connection when a power outage or a broadband disconnection is detected. The switch is accomplished by establishing a connection from a telephone connected to an RJ11 port on the module to a wired channel connected to a backup RJ11 port on the module. Detection for power outage is by comparing the device voltage with a reference voltage, and detection for broadband connection is by sending out a PING packet and waiting to see if a return packet is received.
