  • Egress network service monitor
    Patent number: 6169724
    Abstract: A method of recognizing a call failure related problem occurring at an egress network of a telephone system wherein information relating to call failures occurring at the egress network is provided by an out-of-band signaling system. The method includes determining a tolerable call failure rate, calculating a threshold based on the tolerable call failure rate using a standard deviation, calculating a measured call failure rate at the egress network, and comparing the measured call failure rate to the threshold and recognizing the measured call failure rate exceeds the threshold. In addition, a system for recognizing a call failure related problem occurring at an egress network is described.
