shadowym,

	While I haven't noticed this myself, many people have pointed this out. 
  I can assure you that the prompts in AstLinux 0.4 are the same native 
prompts provided on astlinux.org.  I don't know why they seem to sound 
so much better in AstLinux than with standard Asterisk installs, but as 
I said many people have noticed this.  In theory, the native sounds 
should sound much better no matter how you play them back.  Interesting...
