A system and method for conducting variable VPA testing is disclosed. The method includes provisions to detect or measure the utilization of a trunk line and use that information to establish a level of VPA testing for that trunk line. Although a wide variety of relationships between the utilization and the amount of VPA testing conducted can be used, the relationship is preferably a generally inverse relationship, in which the amount of VPA testing conducted on a particular trunk is reduced as traffic or utilization of the trunk increases. Conversely, as traffic or utilization of the trunk deceases, the amount of testing conducted on the trunk increases.

System and method for conducting variable voice path assurance tests

The present invention uses a software program to analyze all of the SS7 message traffic in a telephone network. By comparing point codes in the message data, the present invention can detect invalid and undesirable network inefficiencies in different types of telephone networks, including for example, wireline, wireless, or hybrid networks.

System and method for detecting SS7 messaging inefficiency

A system and method for detection of invalid and undesirable conditions associated with a telephone network. The invalid and undesirable conditions can include, for example, call looping, misrouting, mass calling, and excessive redialing. Initial Address Messages associated with SS7 protocols are captured, parsed, and analyzed for detection of these conditions. A system in accordance with the present invention can be a device external to a switch that generate the messages. Alternatively, a microprocessor of the switch can be adapted to execute instruction sets disclosed in the present invention.
