Several months ago, I used WildPackets EtherPeek to analyze some VoIP packets I was sending out and receiving.
The tool evaluates packet delay vaiations, jitter, and packet loss, crunching the numbers to derive predictive diagnostics for each call.
With the growth of VoWiFi, tools like this are going to become more and more in demand.
We'll have pricing info when AiroPeek VX ships in less than two weeks. Can't wait to test it out.
