Asterisk at Office with JustVoip or/and VoipBuster

Hi. I have installed an Asterisk 1.8 system with FreePBX 2.9. Everything is ok, I can call between extensions within the lan. But when I want to call outside, it is not working. I have an account with JustVoIP with 10 eur, and other with VoIPBuster without money. I configure both trunks in asterisk but they fail when registering: pc*CLI> sip show peers N a m e/ u s e r n am e Host Dyn Forcerport ACL Port Status 1/1 [login to view URL] D N A 5060 OK (34 ms) 1000 (Unspecified) D N A 0 UNKNOWN 1001 (Unspecified) D N A 0 UNKNOWN 1002 (Unspecified) D N A 0 UNKNOWN VoipBuster/jticsolutions [login to view URL] 5060 Unmonitored pstn/pstn [login to view URL] 5061 UNREACHABLE 6 sip peers [Monitored: 1 online, 4 offline Unmonitored: 1 online, 0 offline] pc*CLI> pc*CLI> sip show registry Host dnsmgr U s e rn a m e Refresh State [login to view URL] [login to view URL] N jticsolution 120 Request Sent 1 SIP registrations. pc*CLI> The current lan configuration is: 1) ADSL Router accessing internet 2) My laptop, wifi connected to router. 3) The Asterisk server, wired connected to my laptop, so my laptop gives it internet. Of course Asterisk server can connect to internet. One of the peer details configurations I have used is something like: u s e r na m e =xxxu s erxxx type=friend secret=xxxpassxxx host=[login to view URL] context=from-trunk canreinvite=no disallow=all allow=alaw&ulaw And the register string: xxus e rxx: Please, could somebody help me with this?. I think I could give you web-freepbx access through ssh-tunneling (but I am not sure)
