sip communicator is crap.  Its trying to do way too much and does not a single thing very well at all.  If they have G729 its not legal to use.

I believe sip communicator does handle g729. It has a strong community and a plugin model (based on osgi) that makes it easily (ok, kinda...) customizable. Of course the FSComm/givesomemoneytotheproject option is the best one. In any case:
