That isn't exactly true - ISDN and IAX (SIP?) support the concept of  
rejecting a call without answering it.
The asterisk dial plan only supports this indirectly. If there is no  
extension that maps to the called number
in the relevant context then asterisk will reject the call without  
answering. I don't think this helps the OP's
situation, but for the sake of the archives I think its worth  
clarifying....
