Abstract

A path diagnosis method and system for a VoIP network includes obtaining information on VoIP calls from the VoIP network using either Call Data Records (CDRs) or active testing, or both. A VoIP call that has a problem is determined between a source and a destination device on the VoIP network, based on the obtained information. Likely call paths between the source and destination devices on the VoIP network are determined. The VoIP network is queried to obtain network data with respect to all devices that exist between the source and destination devices along the likely call paths. A path diagnostics chart is displayed that shows the devices that exist between the source and destination devices along the likely call paths, along with any call issues that exist for each of the devices.
