Hello 

Anyone can recommend me a software-based SIP solution to enable automated periodic voice quality testing (RTP) through a VoIP network ? 
In short, the solution would replicate the customer experience by placing calls on-net from "TEST STATION A" to different DIDs that would each leave through different upstream TSPs and all of the DIDs would ring the same "TEST STATION B". 
Station "B" can either be on-net or outside and will automatically answer the call and then spit out audio (i.e.: a continuous tone), or it may also enter in a loopback mode and station "A" would simultaneously generate and also detect the presence and integrity of the tone. 
The solution should log every performance aspects from each test run and also send an alarm on repeated failures for either no-answers or degraded RTP quality like packet loss, jitter or even problems with the expected payload. 

So far I have seen products from GL communications "RTP Toolbox" that could possibly do it. : http://www.gl.com/rtptoolbox.html 

I would also be interested in other ways like using open source projects like Freeswitch : http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_tone_detect 

I'd appreciate if you can share your experiences for those who have already done that, or simply ideas from anyone else. 


Thank you, 
M.B.
