Hi !

Does anyone know free software, to measure voice quality in MOS scale
(P.800, PSQM, or whatever)? I spent a lot of time on google but didn't
find anything free . It would be nice if it could measure jitter
packet loss echo delay etc ...

Thanks for any advice.

Ethereal on the receiving end can produce pretty graphs and statistics.
Not much use for large scale monitoring though.

There are web sites that try to predict what MOS you will get if you
made a voip call to various destinations. Would that help, or you
trying to take measurements of actual calls?

In case they're useful:

Hi !

I try to find out MOS in my intranet. I've find  some free tools for
voip, but they actually evaluate number for calls ( for SIP, H3232 etc)
not for voice quality.
Thanks for links.
