Abstract: An interconnect device for connecting a Bluetooth compliant cellular telephone to one or more wired telephones on an existing wired network. The interconnect device includes an interface to the wired network that emulates the behavior of a standard trunk line to a central office and includes a Bluetooth transceiver which communicates via short-range radio signaling with a Bluetooth transceiver in the cellular telephone. The interconnect device permits an outgoing call to be placed via the cellular telephone network from a conventional wired telephone by sending dial tone to the wired telephone when the cellular telephone is in range and not in use, accepting a called number from the wired telephone to the cellular telephone to initiate an outgoing call, and establishing a voice link between the wired telephone and the remote answering party via the Bluetooth transceivers and the cellular network.
