asterisk users - Apr 2007 - CallerID Auth

Hi,

in my dial plan I've configured two trunks to make outbound calls (one for
national calls and other international). I want to allow only 2-3 extension
to make use of my international trunk to make outbound calls so I want some
kind of auth. based on their callerid . Please guide.


thanks

Just detect that a call is international, then branch out.  e.g., if 011 is 
the prefix required for international,

[outbound]
exten => _011.,1,Dial(Local/${EXTEN}/international)
exten => _X.,1,Dial(ZAP/g1/${EXTEN})

[international]
exten => _X.,1,GotoIf(${DBEXISTS(international/${CALLERID(NUMBER)})}?:deny)
exten => _X.,n,Dial(ZAP/g1/${EXTEN})
exten => _X.,n,Hangup; just in case
exten => _X.,n(deny),Playback(not-a-valid-number&try-again)
exten => _X.,n,DISA(nopassword,outbound)

This is assuming AstDB contains a family international that includes 
extensions/ID's allowed.  Hope this helps.
