Configuring ISDN caller number callback

This feature allows the device to perform the following operations:
•
Screen incoming calls based on the ISDN caller number.
•
Determine whether to accept a call or initiate a callback according to the screening results.
A callback is a return call from the call receiver (server) to the call initiator (client). The client initiates
a call, and the server determines whether to initiate a callback to the client. If yes, the server
disconnects the call and places a return call to the client.

Overview

The callback feature has the following benefits:
•
Enhanced security—The server initiates a return call to the number configured locally, which
prevents caller number spoofing.
