Can't receive call from outside (HELP)(RESOLVED

Hi, I have a problem triying that my external call come in to my asterisk server with my sip provider, I got the server right now in the DMZ zone and I can place call to a regular phone number but I have problem receiving it. I think the server don’t connect to my SIP provider, because don’t ring or access the voice menu, I call from a regular phone and about a 30 seconds I received a busy signal. I think is something about the route to connect to my provider.
Any idea.

did you watch your CLI to see if there is any activity?


Thanls for youe help, I resolve my problem.
