VoIP (Scalable VN)

Scalable VN gives you the capability to test voice band performance to or from VoIP endpoints in any telephone network. Tests carried out between a physical terminal and a virtual node can help to localise speech performance problems by effectively segmenting the speech transmission path.

Scalable VN provides a reference implementation against which to validate systems. It tests network performance during commissioning stages.
