Anonymous Call Filter (ACF) is part of the Intelligent Call Diversion feature. When it is activated, all incoming calls from anonymous/blocked numbers will be routed to your pre-set second destination (e.g. voicemail).


To turn anonymous call filter on or off, logon to your account and go to the Settings control panel and simply select 'Anonymous'. You will then see confirmation text beneath the heading 'Number Settings', stating "OK! Your request has been accepted."

At the same time, you can also change your second destination (e.g. from landline to voicemail) to make sure the unidentified calls go to the right place.
