Claim:
A method, comprising: (a) receiving a voice call for one of a first and a second subscriber, wherein the first subscriber currently has a first communication device as a home station but is currently registered at a second communication device, wherein the first and second communication devices are serviced by differing switches and/or servers and are concurrently enabled for communication; and (b) applying the following rules: (B 1 ) when the voice call is for the first subscriber, the voice call is received first by a first switch and/or server, and the first switch and/or server determines from an application record that the first subscriber is currently registered at the second communication device and forwards, to a second switch and/or server, a call set up message associated with the received voice call; and (B 2 ) when the voice call is for the second subscriber, the voice call is received first by the second switch and/or server, and the second switch and/or server treats the voice call as mandated by a native station record associated with the second communication device, wherein the second subscriber is able to receive incoming calls to the second communication device, make calls remotely using, as call origination information, a number of the second communication device, and access remotely features of the second communication device and the first subscriber is able to receive incoming calls at, make outgoing calls from, and access first communication device features from the second communication device thereby permitting the second subscriber to be a remote user of the home station while the home station is in use by the another subscriber.
