Caller Display messages not

To be able to receive and display
caller information, you must
subscribe to a Caller Display
Service from your network
provider. For more information

Phone does not ring
Check that the ringer is not
switched off on the phone that
is connected to your Caller
Display 1500.
Check that no other connected
phones are off the hook.
NO NUMBER on the display
Your Caller Display 1500 checks
the content of the caller message
it receives. If it detects a problem
with a message it displays
NO NUMBER
rather than risk
leaving a message with a possible
mistake. This does not mean
that your telephone is faulty.
If you continually receive
NO NUMBER
, call BT free of charge
on
0800 800 150
for residential
customers or
0800 800 152
for business customers, or your
service provider.
