ABSTRACT:
A method and apparatus for automating test procedures to determine if non-emergency signaling message processing errors impact emergency calls, e.g., E911 calls, are disclosed. In one embodiment, the present method alerts network engineers so that crankback procedures to alternative routes can be instituted when these E911 call impacting error conditions are detected in a network.
