Call Screening

You have control to ensure you receive important calls. You can limit the callers that ring your phone, filter callers,
or forward important callers to another number. Calls from anonymous callers, or other callers, can be given
special treatment: either being blocked, sent directly to voicemail, forwarded to another phone number (like your
mobile), or having a custom ring pattern assigned.

Anonymous Call Block

Calls from anonymous callers or phones not sending a caller ID, can waste your time and distract you from other
calls you want to take. These calls can be filtered from even ringing your phone. You can choose to have
anonymous callers either hear a busy signal or a message informing them that you are not accepting calls from
anonymous callers.
Enable/Disable Anonymous Call Block

Step 1 Dial *77 to enable Anonymous Call Block.
• You will hear a prompt saying, "Your anonymous call rejection service has been activated. All incoming
calls will be checked for number privacy before they are allowed to complete to your line".
