Abstract

A method of measuring network quality for VoIP calls comprises setting up a test call from a local IP endpoint to a remote IP endpoint reachable by a logical trunk group associated with the local IP endpoint, receiving statistical data regarding the test call, tearing down the test call, processing the statistical data and generating measurement results, and routing a VoIP call using a route selected based at least in part on the measurement results.
