A method and system are disclosed for preserving caller privacy in an
advanced intelligent network comprising a service switching point and a
second service switching point. The service switching point is adapted to
suspend calls directed to a predefined number and forward signaling
information associated with the call to the service control point. The
service control point is adapted to alter the signaling information if a
privacy restriction indicator in the signaling information is activated
and to forward the altered signaling information to the service switching
point. The method comprises the following steps: forwarding information
identifying a calling party and any privacy restrictions on the calling
party information from the service switching point to the service control
point; and if the privacy restrictions indicate that the calling party
information should not be delivered to the called party, altering the
calling party information and forwarding the altered information to the
service switching point.
