I found the option, it was simply : --translate 170.56.78.123 (as Internet IP)
With this option, I can't be registered by microtelco gw.

In console : translating IP, registering impossible !
----------------
Listening interfaces : ALL:1720
Masquerading as address MY_INTERNET_IP
Enabling H.235 security access to gatekeeper.
Error registering with gatekeeper at "gk.microtelco.com"
OhPhone ended.
----------------

Without the translating option, I can be registered but I can't receive any 
sound and the communication is quickly cut.

In console : no translation, registering easy but no sound :-(
----------------
Listening interfaces : ALL:1720
Enabling H.235 security access to gatekeeper.
Gatekeeper set: bmac 66 7 159 99
Waiting for incoming calls for "MY_ALIAS/1"
Command ? Offhook - dialtone
Playing dialtone
----------------

It's exactly the same problem known with Gnomemeeting.

Yes, as I wrote before, I can do that.
But after being registered, if I want to communicate, I must go into 
parameters ad check the IP translation because without, I can't hear 
anything... That's what I call my little gymnastic.
It's a tip for geek, imagine my wife if I ask to do that ;-)

What you mean with buggy H.323 NAT module ?
It's not as easy to use as expected ?
Waiting for the new IPCop 1.3 (kernel 2.4 at least..)

I know, I continue my investigations  ;-)
