ouch that is what I was hoping against.  This is tricky without making a
call during negitiation to see if there is anything available.  I have
looked at the code and there doesnt really seem to be a way to do this
under the current model ...

You can do some stuff for some channels, sip for example has a recirect,
but that gets into the nitty gritty of a channel driver and codecs
should be free from channel specifics (in my opinion anyway).  

I am trying to work on a cheaper g729 implementation that relieves this
problem as well as a bunch of other issues that may be present.  One
major difference is better support when multiple boxes are used so you
dont have to get X codec licenses per box and instead get X licenses for
an installation.
