Concerning measuring Asteriks voice quality for various connections, we have developed a software that is
successfully used by some of our customers who have Asteriks installed and
perform voice quality monitoring quite easily on their own hardware in
1. Originate a call on the monitoring server, using Asterisk manager
interface, to a server which is running an echo application
2. Monitor both inbound and outbound legs of the call, and save as wav
3. Use AQuA (our product) to compare the wav files.
We would be happy to hear from those who are interested in such solution and will
be looking forward to your feedback. Thank you!
