Thanks for your help Michael.
Thanks to the SIP trace mode, I saw that, as you said, the remote server 
can be contacted but, it can't find the phone with the number 300 :

send 1135 bytes to udp/[PBX IP ADDRESS]:5060 at 07:36:50.305204:
   INVITE sip:300@[PBX IP ADDRESS] SIP/2.0

recv 463 bytes from udp/[FS IP ADDRESS]:5060 at 07:11:33.165472:
   SIP/2.0 404 Not Found
   User-Agent: OxO_GW_710/022.001
   To: <sip:300@[PBX IP ADDRESS]>;tag=f75e19901fe0d4a3eed1295e30a93b53

But the private number 300 exist and work very well. So i guess the way 
to join the endpoint (an Alcatel IP phone) is not the good one. I even 
tried with the public number. I don't think the pbx can find 300@[PBX IP 
ADDRESS], it can only find 300 as this phone already has an IP address.
