Blacklist

Block Calls To Your Telephone Numbers

The online Control Panel allows users to blacklist and block incoming calls from certain numbers, international numbers or a range of numbers, for example all numbers starting 0871. This is ideal for blocking nuisance calls or callers that you don’t want to speak with. STOP wasting time with spam calls, block calls from locations you’re not interested in and MAXIMISE your efficiency. The blacklist enables you to add a list of numbers and comments via your online account to block. The blocked caller would hear a personalised message saying: “Calls are not currently being accepted from this number.”
