Abstract

A method and server for providing intermediate telephone call notification services while increasing the reliability of other call handling services is disclosed.
Calls including called party identifier are received at a switch (16,28) forming part of a network (26). The calls are forwarded to a first available notification server (12, 18, 34) in communication with the switch (12, 18, 34), preferably using pre-configured route lists. Each server (12, 18, 34) is capable of providing call notification service for at least some subscribers (10, 22, 30). A
server (12, 18, 34) receives a call, including a called subscriber identifier and determine whether the call should be processed as a call for a primary or a secondary subscriber. For calls for a primary subscriber, the server (12, 18, 34) dispatches an indicator of the call. For a call to a secondary subscriber the server forwards the call to a call handling system, such as a voice mail server (36, 38, 40), interconnected with the network.
