Method and apparatus for management of voice-over IP communications
First Claim
1. A method, comprising the steps of:
- (a) obtaining information relevant to the quality of service of voice calls being transmitted from a first location to a second location via an IP network;
(b) calculating a parameter based on said information; and
(c) accepting a new call into the IP network in the case of said parameter not exceeding an upper threshold.

Abstract
A method and apparatus for analyzing current voice call quality in an IP network before allowing a new voice call to enter therein. Circuitry in each gateway between a PSTN and the IP network obtains information from the IP network regarding the quality of voice call traffic being transmitted from one gateway to another gateway. A parameter is calculated by the circuitry based on this information. This parameter is compared to predetermined thresholds to guarantee acceptable quality for a new voice call that is attempting to enter the IP network. The circuitry includes three circuits. A first circuit passes voice call data to the IP network. A second circuit polls the IP network about traffic information transmitted therein. A third circuit processes the polled information to determine whether the voice call data is to be accepted by the IP network.
