[OpenSIPS-Users] can't register x-lite softphone to opensips

[gmail]

i can not register the x-lite softphone to opensips :
i created the user like this:
  [root at OpenSER ~]# opensipsctl add 1001 1001
                                 new user '1001' added"
 and i put the username and password in x-lite configuration menu and put the proxy IP address , and when i trace what is going on by Ethereal it gives me 
[destination unreachable (Host administratively prohibited]
