Calling
Line Identification is a feature that has been available in
most areas of the UK for some time.
On analogue lines this feature sends information in between
the first and second rings of the phone. The caller can prevent
this information from being sent if they choose to do so.
As phone systems don't tend to support CLI from analogue
lines you need to specify ISDN channels instead of a group
of analogue lines. The Calling Line Identity can display information
such as the telephone number, time of the call, the date of
the incoming call and if the details are in the memory of
the phone, the name of the caller.
Integration with computer software can also display the full
name and address of the caller including accounts and sales
analysis information. Whilst this was predominantly used by
mail-order companies, to identify the customer calling and
their account details and other information, before the call
is even answered, this is now very affordable for smaller
organisations.
If the person who is calling does not wish for their information
to be displayed, the information can be blocked by entering
a special code prior to dialling a phone number. In the UK
this is "141" and is used by only 6% of callers.
