[asterisk-users] Suddenly the voice become like robot (cutting), like sick man

Fri Aug 22 09:22:22 CDT 2008

It's tough to say why a voice would start sounding like a robot. There  
are so many variables that could effect your Asterisk server.

I always go for process of elimination when I have a problem similar  
to this with call quality.

What I would do is install an end point on the same local network /  
subnet as your asterisk server (either a hard phone or a soft phone  
like X-Lite by Counterpath). Register the phone locally with your  
Asterisk server and make some calls or put an echo tester up.

If things sound good, you know your Asterisk server is working just  
fine, and the problems lies somewhere on your network between the  
Asterisk server and whatever gateway / device. If it sounds awful, and  
the codecs match, then it's time to start troubleshooting the server.
