Jean-Michel,

	Asterisk does not really have support for G723.  It can do passthrough, 
but it will not transcode it.  NuFone does not support it.  That is 
where your error is coming from.  Make sure that you do this:

iax.conf:

disallow=all
allow=ilbc
allow=gsm
allow=ulaw

sip.conf:

disallow=all
allow=ilbc
allow=gsm
allow=ulaw

I think that should do what you need.  Please read up on codecs at
http://www.voip-info.org/wiki-Asterisk+codecs
