How much would new phones cost?  If they cost more than $10 each then 
you will spend more money by buying new phones rather than buying a G729 
license.  Remember G729 is licensed on a per simultaneous channel basis. 
  i.e. if you buy 10 licenses you can have up to 10 G729 channels in use 
at any one time.  You do not need one license per phone.
