Abstract
There is disclosed a system and method for monitoring the performance of a multi-line automated telephone system and detecting complete or intermittent faults on the incoming phone lines and in interactive applications accessed by the automated telephone device. The system gathers and analyzes statistical parameters associated with each incoming phone line and compares the parameters with those of other phone lines and with past statistical averages to detect out-of-tolerance lines. The system also gathers and analyzes statistical parameters associated with the execution of various applications and compares the parameters with past statistical averages to detect out-of-tolerance accesses to the applications.
