I suppose that it's sort of subjective, but I think it sounds  
_awesome_.  It's a huge difference in quality to me.  You just need to  
try it out.  :)

Asterisk 1.4 does not support transcoding of G722.  Asterisk 1.6 does  
support transcoding, so it can be used in combination with any other  
codec that Asterisk supports.

Asterisk should work fine with any phone that supports that codec.   
Personally, I have only used it with Polycom phones.  Also, again,  
Asterisk 1.4 only supports G722 passthrough, where as Asterisk 1.6 has  
full support.
