This caught my interest, so I did some reading.  Unfortunately, it  
looks like that isn't the case :(

   http://www.sipro.com/g729_faq.php

"Is the G.729 Consortium License only required when the ITU-T G.729  
standard is used for encoding signal ?  No. The license is required  
for both encoding and decoding voice signal."

There has to be same way to provide at least a framework for  
supporting G.729 though. Maybe some way to use those codec licenses  
they sell for VoIP boxes in Wireshark if the user really wants to and  
pays for the license?  I know that gets hairy too, but Asterisk seems  
to pull it off.
