[asterisk-users] Suddenly the voice became karbage (like robot) using Asterisk

[bilal ghayyad]

Dear Dany;

First of all, thanks for sharing us the knowledge as really I got tired from it. 

I am using Fedora, actually I did not get to know how could the fedora cause the problem at memory level and hard disk level?

Also, how can I resolve it?

Regards
Bilal
