Yea, most of our customers can tell the difference between g729 and g711.  When it comes to business calls (as opposed to residential), clarity of the call is even more important!   Some customers demand that we move back to G711 and others just put up with it because of the increased call capacity that goes along with g729.  

We've also found that the quality of the handset sold to the customer can make a huge difference in their acceptance of g711.  Some handsets just excaserbate the poorer quality of g729 calls because the speaker/mic hardware isn't all that clear in the first place.

Your customers must have bad hearing. There's a major difference.
