Abstract
In one configuration, an enterprise network is provided that includes geographically dislocated first and second network regions 202 and 206, the first and second network regions being in communication with one another through first and second networks 252 and 248 and respectively comprising first and second gateways 220 and 224 and first and second groupings of links connected to the second network 248. A common electronic address is associated with the second grouping of links. In response to a request from a first subscriber to initiate a communication session with a second subscriber in the other network region, a media server 200 determines that the first network 252 is currently incapable of supporting the bearer channel for the session. In response, the first gateway 220 transmits the common electronic address to the second gateway 224. After the common electronic address is received by the second gateway 224, the first gateway 220 transmits in band to the second gateway 224 an identifier that is used to establish the communication session.
