Abstract
A telecommunications system and method is disclosed for re-directing failed calls to H.323 endpoints within an H.323 system by adding a unique re-routing release cause to a Release Complete message in the H.225 protocol that indicates that the call should be re-routed to another number. The Gatekeeper within the H.323 system stores the alternative number for the H.323 endpoint, and upon reception of this new re-routing cause in the Release Complete message, the Gatekeeper establishes a new leg of call to the alternative number.
