[Asterisk-Users] x-ten lite error

[asterisk at frameweb.it]

Hallo,
I have just set up asterisk at home and configured two extensions, 200 and 201
with x-ten lite.
Ext 201 seems to be ok (i tried to dial 200 and the system answered that
the extension was not available atg the moment and let me leave a voicemail
message),
Ext 200 seems to be "blocked": for any number that i try to dial I always
receive the busy tone and the message "Call failed: 403 forbidden" appear
on the softphone screen.

Any suggestion?
