[asterisk-users] Voice quality assessment in Asterisk

[Jason Aarons (US)]

Those boxes run around $50k USD, I've only seen them once back in the late 1990s.

At work for customer consulting we have very expensive site licenses for Prognosis IPT Assessor which generate great looking pdf reports.

We also use Cisco IOS IP SLA however it doesn't have a reporting mechanism.

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.

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!
