ABSTRACT:
When a terminating call is forwarded by a CTI-enabled switch to an off-switch destination, the associated CTI controller is notified of the delivery of that call and in response the controller records that destination number as busy and invokes a call back when free request in respect of the destination number. When a notification is received at the CTI-enabled switch that the destination number has become free, the controller is notified, and in response records the destination number as free. The CTI-enabled switch may comprise a switch in combination with a telephony card.
