Your question demonstrates a fundamental lack of Asterisk concepts and knowledge.  You should start by reading http://www.asteriskdocs.org/ and go from there.    Asterisk is not something you can learn in a few days.

Thank you Julian,

would it be possible to block calls to international calls except certain countries? I just want to make sure that if attackers try to place calls outside the states they not succeed.

I use this

exten => _0041,1,Log(NOTICE,Pin Code for Switzerland calls)
        same => n,Playback(silence/1)
        same => n,Authenticate(9084,,4)
        same => n,Macro(outgoingTrunk,${EXTEN})
        same => n,Hangup()

It  uses  a  fixed PIN number which calls a macro which deals with the
actual  dialling,  but  a  standard  Dial command would work here too.
Quick  and  easy, but there are lots of options. If the correct PIN is
not entered, the call is not made.

Best regards,
 Julian                            mailto:jb_soft at trink.co.uk<mailto:jb_soft at trink.co.uk>
