ABSTRACT:
A wireless communications interface couples wireless service to conventional wireline phone appliances. In one embodiment, the wireless communications interface is connected to the phone appliances through existing phone jacks. This allows a user to place and receive calls over a wireless network using the existing wireline infrastructure in a building. By using the invention, users can consolidate their portable and fixed phone service with one of the multiple wireless service providers and bypass the wireline service provider entirely, if so desired. In a second embodiment, the wireless communications interface is directly connected to the phone appliances, bypassing the installed wireline infrastructure. In a third embodiment, both wireline and wireless service are operative, and the wireless communications interface may include logic arbitration to route multiple calls to multiple phone appliances.
