Object: Blocklist

The Blocklist object is used to block incoming calls received from specific phone numbers and empty or alphabetical CLIs. If the calling number exactly matches the configured settings or phone number, then the incoming call will be automatically terminated and will not be passed to objects connected to the right-hand side of the Blocklist object.

The information to be entered for this object is:

• The name of the Blocklist object.

• Additional Settings:

• Block empty Caller IDs - When the source number field is empty or null, the call will be terminated.

• Block Caller IDs containing letters - When the source number field includes alphabetical characters, the call will be terminated.

• The blocklisted phone numbers - A list of the exact phone numbers to be blocked. There are no limitations on the format (such as E.164) or the number of digits used in listing these phone numbers, so as to allow for maximum flexibility in CLI matching. Multiple numbers may be added as required.

Phone numbers previously added to the Blocklist object may be deleted by clicking on the “X” icon to the right of the number.

A simple usage example of the Blocklist object is shown below, where the blocklist filter is applied to all incoming calls before those calls are processed by the company’s voice menu.
