Abstract
Increased reliability for intelligent call processing systems is provided by collecting information from communications between the network database, the subscriber database, and the network switch. Message transfers between these network elements are monitored and correlated to identify those messages corresponding to a particular call. The messages for the call are analyzed to determine which database generated the instructions for routing the call. In particular, by comparing the routing number returned to the interexchange switch with the routing instruction information supplied by the subscriber's database, it can be determined whether the call was routed according to instructions from the subscriber's database.
