I read http://bugs.digium.com/bug_view_page.php?bug_id=0003346
This should be a good solution for my need :

exten => _**393.,1,SetPreferredCodec(ulaw)
exten => _**393.,2,Dial(IAX2/fwdnum:fwdpwd at iax.fwdnet.net/${EXTEN:5})

So any incoming call to FWD would be asked to use ulaw first... if it 
can, we'll have native bridging :) great ! Will this be patch be soon a 
part of the main CVS ?

I wondering also if it would not be possible to directly ask peers what 
codec(s) they can use, so if they can use the same codec, just ask them 
to use it and native bridge them ?
