Each phone or phone group can have the codecs configured.  Simply put G.729 as 
the highest perferred codec and the phone will use that codec first.  you can 
also restrict which codecs SipxBridge allows and restrict that to G.729 as 
well.  But that would not affect intraoffice calls.

This might be off topic if it's not something that sipx gets involved in but 
it's possible I'm not aware of a method by which it could control call flow 
based on codec. From what I understand, sipx doesn't care what codec is being 
used, a voip packet is a voip packet. 

I need to find a way of saving bandwidth. I would like to have all remotes 
using only G.729 but since sipx doesn't handle codecs, I'm at a loss on how to 
accomplish this. Vonage for example allows the user to pick between three 
settings so I imagine this means they are either controlling the codec at their 
end or are sending a new profile to the remote device? 

Are there any ways of accomplishing this? It's mainly remote to remote that I'm 
having a problem with.
