[Asterisk-Users] Display "Confideltial" or "unknown" on called id display

[Andre Courchesne - Consultant]

Hi,

   When making a call from an Asterisk box over a PRI connection, I am 
able to set the Caller ID phone number to what ever I want. This works find.

   How to I make the called party callerid display "Confidential" or 
"unknown" as we sometimes see ?
