The display will flash CALL WAITING 
and the new call indicator will increase 
one count. The display will also show 
you the name (if saved in the directory) 
and the number of the waiting caller.
Instead of the engaged tone, the second 
caller will hear an announcement to 
hold on as you are aware that there is 
a second call.
If the RECALL button is not pressed 
within 20 seconds then the waiting 
caller’s details will be replaced by the 
information that was displayed before 
the new call arrived.
Note
The second caller will only be 
charged for their call from 
the moment you answer and 
not while they are waiting for 
your initial contact.
You can answer the second call, 
without disconnecting your first 
caller, by pressing the RECALL 
button. The first caller will be 
put on hold. 
Note
If you press RECALL and 
answer the second caller, the 
new call indicator will go 
down one count. If you do 
not answer the second call, 
the new call indicator will 
store the call as new in the 
calls list.

Voice mail indication
If you have subscribed to BT’s BT 
Answer 1571, Call Minder, or another 
network messaging service your Decor 
310 will indicate when you have 
received a voice message, by showing 
the icon on the display.
BT Answer and Call Minder are invisible 
answer machines located at your local 
exchange which will take messages 
when you’re out, engaged on another 
call or on the Internet.
To enable your Decor 310 to let you 
know you have messages you must first 
subscribe to a network messaging 
service.
BT Answer 1571 is a basic answering 
service and is completely free of 
charge. To activate the service dial 
Freefone 0800 003 800.
For information on Call Minder, call 
BT on Freefone 0800 800 150. This is 
a chargeable service.
Alternatively, call your Network Provider 
for more information.
Caller information not available
With some incoming calls the telephone 
number of the caller is not available and 
cannot therefore be displayed.
In this case, your Decor 310 provides 
you with some explanatory information 
about the type of call received. This will 
be in the form of a text message and 
will be one of the following.
UNAVAILABLE
The number is unavailable.
WITHHELD
The caller has withheld their number.
RINGBACK

OPERATOR*
The call has been made via the 
operator.
PAYPHONE*

NO NUMBER
See ‘HELP’ section. This message will 
not be stored in the calls list.
*Some text messages can have numbers associated 
with them. Your Decor 310 will alternate between the 
text message and the telephone number. They will be 
displayed for 5 seconds each.

IMPORTANT
The  icon is activated by a stutter 
dial tone which you can hear when 
you pick up your phone, BT Select 
Services, such as Call Diversion and 
Call Barring use stutter dial tone so 
therefore will cause the  icon to 
be activated even if no messages have 
been left.
IMPORTANT
After an incoming call, or after lifting 
the handset, your Decor 310 will 
check the line for any messages. You 
may experience a slight delay before 
the  icon is displayed.
To listen to voice messages
When the  icon is 
displayed, dial 1571 for BT 
Answer 1571 or Call Minder 
(or your access code) to access 
your messages.
Follow the announcements to 
Play, Save and Delete your 
messages.
Press the 1 button to play your 
messages.
Press the 2 button to save 
your messages.
Press the 3 button to delete 
your messages.
The  icon will remain on 
the display until you have 
listened to all of your voice 
messages.
Note
Call your Network Provider 
to confirm your access code.

If you have any difficulty using your 
Decor 310, look in this section first for 
solutions to the most common problems.
No dialling tone
Make sure the telephone line cord is 
plugged into the telephone socket at the 
back of the unit and that the telephone 
line cord is connected to your wall socket.
Check that no other extension is in use.

properly or goes blank
Check whether the battery is fitted 
correctly.

are off the hook.
Check whether you have too many 
phone extensions in your home or

to the ‘Technical information’ section on 
page 24.
NO NUMBER displayed
Your Decor 310 checks the content of 
the Caller Display messages 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 your 
telephone is faulty.
If you continually receive NO NUMBER 
messages, call:
Freefone 0800 800 150 for residential 
customers. 
Freefone 0800 800 152 for business 
customers.
Or your Network Service Provider.
