asterisk users - Jan 2006 - no nat, but one way only audio (more info)

I've an asterisk 1.2 connecting to a quescom gateway via SIP, the caller 
(asterisk) can hear the called, but the called hears nothing.
Since both machines are on public ip, what other problem can it be ?

There's one configuration working :

lynksys pap  -sip-> asterisk server -sip-> quescom
this way both sides can hear voice

but with :
lynksys pap connected to a switch -sip-> asterisk client (on the same 
switch with one eth and on internet with another one) -iax> asterisk 
server -sip-> quescom
voice can only be heard <---this way--

the client is 1.0 and the server 1.2

Turn off any firewall both on the caller and the called side.
