What is BT Call Blocking?
BT Call Blocking puts you back in control by allowing you to choose the
calls you want to take and those you want to block. This means that any
caller not on your contact list or already blocked is required to announce
their name prior to getting through, allowing you to choose which calls to
accept or reject.
• If you turn BT Call Blocking off, all calls will be allowed through, even if
they’re already on your blocked list. See page 23 to change settings.
• You can customise BT Call Blocking to block certain types of call e.g.
International, Number Withheld etc. See page 28 to change settings.
• For compatibility with BT 1571 (or another voicemail service), make sure
the answer delay is set for your answer machine to answer before the
voicemail service. For BT 1571 do not set the answer delay to more than
5 rings.
