Can I use the BT call prefixes 141 and 1470 to hide or reveal my telephone number on outgoing calls?
SuperLine will accept calls using either of the two dial prefixes, but only when dialled manually, as the dialler is set to route any call starting with the digit ‘1’ through BT. To make a manual call using either of these codes you should dial as follows:- – 141 or 1470 (to hide / reveal your phone number as required), then – 1461 to pass the call to SuperLine, then – the full number you require E.g. (1): To hide your telephone number from a person you wish to call in USA on the number +12345678900, you would dial 14114610012345678900. E.g. (2): To reveal your number which is normally blocked to a number in the UK 01234567890 you would dial 1470146101234567890.
