asterisk users - Oct 2010 - Voice quality assessment in Asterisk

Hi,

How do you typically test voice quality in Asterisk? For example if you like to
do load testing, or monitor voice quality and get notified if certain calls had
bad quality for proactive maintenance?

Thank you!

Best Regards,

The professional way is to do a series of test calls, play a reference
file and record the audio at the incoming side. You then use both files
to calculate a MOS score. This method is used by telco's to do quality
checks.
