A method and apparatus for routing calls for a subscriber based on the probability of call completion for a set of routing destinations. The present invention operates to route calls to destinations in a routing list, maintain a success indicator for each routing attempt, ant route calls based on the success indicator. When a call is received, the routing list is sorted according to a call completion probability indicator associated with each destination. Destinations will be selected in accordance to the sorted order (325), and the call will be routed to that destination (350). If the routed call is not answered (355), the next destination will be extracted from the list and the call will be routed thereto (350). If the call is answered (355), an identification announcement is provided to the answering party (360), and processing will wait until disposition information is received (365). If the disposition information indicates that the call is accepted by the answering party, the call completion probability indicator will be updated and the call will be established (375). If the disposition information indicates that the call is rejected by the answering party, the call will be routed to a default destination and the call completion probability indicator will be updated (380). If the call is neither accepted nor rejected, the next destination will be extracted from the routing list and the call will be routed thereto (350). |
