Abstract
A system for (and a method of) selectively establishing communication with one of plural devices associated with a single telephone number during a disaster or disaster recovery period. In a preferred embodiment, the system includes two wireless connection units, each connected between a respective private branch exchange (PBX) network and a public switched telephone network. Each wireless connection unit preferably serves as a gateway between its respective PBX network and one or more remote communication devices. The wireless connection units replicate each others databases. In the event of a disaster that destroys or renders one of the wireless connect/PBX networks inoperable, telephone calls destined for the inoperable network are seamlessly routed to the operable wireless connect/PBX network. Since the operable wireless connection unit contains information for both networks, inbound, outbound and extension to extension calls for each network can be handled despite the disaster.
