Abstract
In one configuration, the present invention is directed to an enterprise network that includes geographically dislocated first and second network regions communicating with one another through first and second networks and respectively comprising first and second gateways and first and second groupings of trunks. A media server is positioned in the first network region that includes a routing agent. When a WAN outage occurs, the routing agent, using a dial plan, maps the dialed digits to an electronic address addressable over the PSTN and routes the call over the PSTN to the destination second communication device in the second network region.
