Caller-ID is the service that allows you to see the phone number of the caller when you receive a phone call. You will be familiar with it from your mobile phone.

In the UK all standard landlines are capable of receiving Caller-ID, though you do have to ask your network operator to turn it on. BT provides the service free as part of their Privacy at Home initiative, but other network operators may charge a monthly fee. Cable phone lines can also receive Caller-ID, though it is not available in some areas.

trueCall offers you extensive protection against nuisance calls, even if you don’t have Caller-ID delivered by your network operator.

• The ‘Whisper’ facility – trueCall answers the incoming call and asks the caller to say their name. It then rings the phone, tells the user who is calling and asks then whether they want to accept the call, send it to the integrated answering machine or play a polite rejection message to the caller.
• The ‘Zap’ facility can be used to send a polite rejection message to the caller during an incoming call.
• The optional Shield feature (turned off by default) asks callers to press a key on their keypad to get through to the caller. This is particularly effective at stopping recorded message calls.
• The optional Code access feature (turned off by default) which asks callers to enter a secret PIN in order to ring your phone – you would only give this Pin out to friends and family.
• Call screening using the integrated answering machine.
• Missed call reporting.
• Night shield.
• The optional Call recorder (upgrade option).

We do recommend, however, that you get your network operator to turn on Caller-ID as this gives you even more features – Star list (a list of friends’ numbers who will automatically bypass Whisper and Shield) or a Zap list (a list of numbers that will be automatically rejected), anonymous caller rejection, Starred callers only, International override, etc.

Silent calls occur when automated systems used by call centres dial more numbers than staff can deal with. The system abandons the call when there is no agent available, leaving an eerie silence on the line.

Ofcom believes the companies behind these calls are mainly involved in telephone marketing, market research, financial services, including debt recovery, and “number scanning.”

Number scanning (also known as ‘pinging’) where calls are made to find out which telephone numbers, out of a range of numbers, are in service or not. As soon as a tone is received which establishes the status of a particular number the call is terminated. This activity is carried out in order to develop lists of active telephone numbers and to compile lists of contact details that can be sold .

Caller ID spoofing is a method in which a person can cause the telephone network to display a number on the recipient’s caller ID display which is not the number of the originating caller.  Since caller ID spoofing can make a phone call look like it’s coming from any phone number the caller wants and because people usually assume a call is actually coming from the number being displayed (and therefore, the associated person, persons, or organization), all kinds of things (both legal and illegal) can be done with such a manipulative ability.

trueCall remains the only solution to these problems!
