Ok, I got it: problem is echo cancelation. If it's activated I have my=20
audio problems.

I remain my test schema (echo test from FWD):

iaxComm - asterisk - internet - FWD Iax

Concerning codecs, FWD allow *only* Ulaw. My * box accept in this order=20
(ilbc,gsm,ulaw,alaw).

In iaxComm:

iLBC: ok but quality is not so good (choppy)
GSM: perfect but I only hear called party, my recorded voice is never=20
coming back (or sended?)
ULAW: perfect but ... echo and over 6 sec delay.

If on my * box I authorize g729, no audio at all.

Waiting your comments if any.
