controller is configured to communicate over a plurality of networks with a plurality of devices, the plurality of networks including a first network and a second network and the plurality of devices including a first device and a second device, the first device being within or proximate the elevator, wherein the plurality of devices are configured to communicate over a third network, and wherein, while the plurality of devices are communicating over the third network, the controller selectively effects a communications bridge over the plurality of networks between the plurality of devices and supersedes the communication over the third network. ## Claims ### Claim 1 An elevator system comprising an elevator including a controller, wherein the controller is configured to communicate over a plurality of networks with a plurality of devices, the plurality of networks including a first network and a second network and the plurality of devices including a first device and a second device, the first device being within or proximate the elevator, wherein the plurality of devices are configured to communicate over a third network, wherein, while the plurality of devices are communicating over the third network, the controller selectively effects a communications bridge over the plurality of networks between the plurality of devices and supersedes the communication over the third network, and wherein the controller obtains a communications address for the second device from the first device. ### Claim 2 (depends on 1) The system of claim 1 wherein the first network, the second network and the third network apply mutually different protocols and communicate on mutually different frequencies. ### Claim 3 (depends on 2) The system of claim 2 wherein the first network is a personal area network, the second network is a wide area network, and the third network is a cellular network. ### Claim 4 (depends on 1) The system of claim 1 wherein after effecting the communications bridge, the controller selectively terminates the communications bridge to resume communications between the plurality of devices over the third network or terminate communications between the plurality of devices. ### Claim 5 (depends on 1) The system of claim 1 wherein the elevator includes an interactive panel and prior to effecting the communications bridge, the controller receives a first request through the panel to effect the communications bridge. ### Claim 6 (depends on 5) The system of claim 5 wherein prior to terminating the communications bridge, the controller receives a second request through the interactive panel to terminate the communications bridge. ### Claim 7 (depends on 1) The system of claim 1 wherein the controller applies VoIP over the second network to effect the communications bridge. ### Claim 8 (depends on 1) The system of claim 1 wherein the controller is configured to receive a plurality of first requests from a respective plurality of first devices including the first device that are within or proximate the elevator to effect a respective plurality of mutually independent communications bridges with a respective plurality of second devices including the second device. ### Claim 9 (depends on 8) The system of claim 8 wherein the controller is configured to independently effect and terminate the respective plurality of communications bridges. ### Claim 10 A method of effecting a communications bridge with an elevator system, the elevator system comprising an elevator including a controller, wherein the controller is configured to communicate over a plurality of networks with a plurality of devices, the plurality of networks including a first network and a second network and the plurality of devices including a first device and a second device, the first device being within or proximate the elevator, wherein the plurality of devices are configured to communicate over a third network, wherein, while the plurality of devices are communicating over the third network, the method comprise the controller selectively effecting the communications bridge over the plurality of networks between the plurality of devices and supersedes the communication over the third network, wherein the controller obtains a communications address for the second device from the first device. ### Claim 11 (depends on 10) The method of claim 10 wherein the first network, the second network and the third network apply mutually different protocols and communicate on mutually different frequencies. ### Claim 12 (depends on 11) The method of claim 11 wherein the first network is a personal area network, the second network is a wide area network, and the third network is a cellular network. ### Claim 13 (depends on 10) The method of claim 10 wherein after effecting the communications bridge, the controller selectively terminates the communications bridge to resume communications between the plurality of devices over the third network or terminate communications between the plurality of devices. ### Claim 14 (depends on 10) The method of claim 10 wherein the elevator includes an interactive panel and prior to effecting the communications bridge, the controller receives a first request through the panel to effect the communications bridge. ### Claim 15 (depends on 14) The method of claim 14 wherein prior to terminating the communications bridge, the controller receives a second request through the interactive panel to terminate the communications bridge. ### Claim 16 (depends on 10) The method of claim 10 wherein the controller applies VoIP over the second network to effect the communications bridge. ### Claim 17 (depends on 10) The method of claim 10 wherein the controller is configured to receive a plurality of first requests from a respective plurality of first devices including the first device that are within or proximate the elevator to effect a respective plurality of mutually independent communications bridges with a respective plurality of second devices including the second device. ### Claim 18 (depends on 17) The method of claim 17 wherein the controller is configured to independently effect and terminate the respective plurality of communications bridges.
