System and method for interfacing plain old telephone system (POTS) devices with cellular devices in communication with a cellular network

摘要

A system and method are presented for interfacing multiple plain old telephone system (POTS) devices with multiple cellular devices in communication with a cellular network to enable efficient communication among these devices. In a broad sense, the system includes an interface configured to function as a bridge between the POTS devices and the cellular devices. The interface selectively routes call attempts from a POTS device to one of a group of cellular devices which connect the calls from the POTS device over the cellular network. The interface may be configured to detect a key sequence for selecting a particular cellular device in the group during an outgoing call attempt from the POTS device. The interface then routes the outgoing call to the selected cellular device. The interface may also be configured to detect a telephone number entered into the POTS device during an outgoing call attempt and route the outgoing call to a particular cellular device based on criteria pre-programmed in the interface. The interface may also be configured to generate distinctive signaling, such as ring tones, for the POTS devices to distinguish incoming calls to the group of cellular devices.
