I've had some high hopes for recqual, though I have to admit I've not used it other than to get it running once. It's an end-to-end voice quality analysis system which creates looping calls with known audio patterns,and then self-examines the audio in both directions to determine if there is any unusual result in the sound comparison. Has anyone used it at length? Is anyone interested in helping develop this platform? It seems like a fairly universal solution to monitoring voice quality in a network, in a truly "as-the-user-sees- it" manner. It has Asterisk as its core, but could work in conjunction with any VoIP or even TDM platform as it is simply a call generator/receiver. http://www.voip-info.org/wiki/view/Recqual JT
