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.

• You can customise BT Call Blocking to block certain types of call e.g. International, Number Withheld
etc. See page 22 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.
