Some people suffering from dementia or obsessive compulsive disorder dial the same phone number repeatedly. They may call the speaking clock, a doctor’s surgery, or a member of the family. This can run up high phone bills and be a nuisance to the people who receive the calls.
trueCall Secure’s outgoing call barring feature allows you to block calls to certain phone numbers (or number ranges). When your relative dials one of the barred numbers they will just hear an unobtainable tone. This stops the call disturbing the called party, and prevents a bill being run up. Repeated failures to get through may discourage your relative from making further calls to these numbers.
You can block calls to whole ranges of numbers - for example calls to premium rate lines, international calls, or calls to a particular geographic region. As well as blocking calls dialled with the full dialling code, you can also block calls where only the local number is dialled.
Note that if trueCall is disconnected or powered down your relative will be able to call any number they want.
