Abstract:
1. An apparatus comprising: a database; and one or more processors coupled to the database and configured to: detect a system fault associated with a call, where the call has an associated dial pattern; identify a route list associated with the dial pattern, where the route list identifies a route of transmission of the call to an intended destination; identify a gateway from the route list which is associated with the system fault, where the system fault indicates that the call failed to reach the intended destination via the gateway; identify a number of dial patterns associated with the gateway including additional dial patterns other than the dial pattern associated with the call; rank an impact of the system fault on an Internet Protocol (IP) telephony system or on an external network that is interfaced to the IP telephony system by the gateway, where the rank of the impact of the system fault identifies a reduction in an available traffic load of the IP telephony system, where the available traffic load after the system fault was detected is less than a traffic load before the system fault was detected, and where the rank of the impact of the system fault is determined, at least in part, according to the number of dial patterns associated with the gateway; and generate a fault message comprising the dial pattern and a description of the rank of the impact of the system fault, where the description of the rank of the impact is stored on the database, where the fault message further comprises a fault code indicating a type of the system fault.
