asterisk users - Dec 2006 - No caller ID, no incoming call

Is it possible to reject all incoming calls that do
not have a CID?

Could I do something like that (modified version from
the book): 

exten => 123,1,GotoIf($[${CALLERIDNUM} = ]?20:10)
exten => 123,10,Dial(Zap/4)
exten => 123,20,Playback(abandon-all-hope)
exten => 123,21,Hangup(

Alternatively, what's the privacy.conf file for? What
does it mean for a user to have to chances to 'enter
his CID' else his call is rejected?

Thanks,
Jez

Try to search for the PrivacyManager application.
It does 'check' if the CallerID is present, if not, it will play an 
announcement to ask the person to 'type' their phone number, and it will
  allow you to then accept it.
