22Caller Display and the calls list
IMPORTANT
To use Caller Display you must first subscribe to the service from your network provider. A quarterly fee may be payable.
For more information on BT’s Calling Features, call BT on Freefone 0800 800 150.
Caller information not available Occasionally the telephone number of the caller is not available and cannot therefore be displayed.
In this case, your BT Studio 1100 will show one of the following explanatory messages:
WITHHELD
UNAVAILABLE
INTERNATIONA(L)
OPERATOR
PAYPHONE
RINGBACK
If the telephone number is longer than 12 digits, then only the last 12 digits will be displayed.
If you subscribe to a Caller Display service you can see your caller’s number on your handset’s display (unless it has been withheld) before you answer the call. If you have stored the caller’s name and number in the phonebook then they will be shown alternately in the display.
Whether you answer a call or not, the caller’s phone number is stored in the calls list.
When you have new entries in the calls list the 
icon will flash in the display.
When all the entries have been viewed, the 
icon will disappear.
Up to 30 phone numbers can be stored in the calls list. When the calls list is full, a new call replaces the oldest.
Each stored number can be up to 20 digits and each name up to 12 characters long.
