I just tried g729 with teliax this morning. It worked fine in both 
directions using three different did's from them.  I did have one
test call where audio was one way though.

During those test calls I watched the CLI and the calls definitely
were g729 without a doubt. I used the exact same teliax server you
show above.

I'm running cvs-head from yesterday.

If you do a iax2 debug, you should be able to spot which system is
not compat with g729. That should lead you into diagnosing the 
problem a little deeper.
