I think you're right, that you don't need a license at all to pass g729
directly or even through asterisk. It's only when you are transcoding
that you need a license.
Make sure your phones are actually SELECTING the g729 codec within
asterisk. Just because the phone is set to prefer it, means nothing.
Verify that your asterisk extensions give highest priority to g729.
