To accept a waiting call 
If another extension presents you with call waiting, this will be 
indicated on your display and you will hear the call waiting tone, 
provided your extension is not protected against call waiting 
tones. 
Select one of the options presented on the display. 
 
 
Note 
 
If you ignore the Call Waiting tone for a short period the Call 
Waiting offer is rejected and the calling telephone is presented 
with the message ‘Call Waiting Rejected’.  
Call Waiting from external calls 
If you are on a call and your extension is presented with an 
external call you will hear a call waiting tone provided your 
extension is not protected against call waiting tones. 
The line the call is on will be indicated on your display. If you 
select the second call, by pressing the line key associated with 
it, the first call will be automatically released. 
Call Park 
The Call Park feature allows you to put an external call on 
special hold by ‘parking’ it in the system. Any extension may 
then pick up the call. 
To park and retrieve a call 
On a featurephone, select ‘Call Park’ on the display. 
‘Pick up park’ is then displayed on the top line on the display on 
all featurephones.  Select this option to retrieve the parked call. 
 
Note 
 
Only one call may be parked in the system.  A parked call will 
recall after three minutes  
On a standard telephone, the code is R712 to park a call and 
712 to retrieve it. 
Storing and redialling caller numbers 
If you subscribe to the Caller Display Service (CDS), the 
network sends the telephone number of callers to the BT Micro  
(provided the caller has not elected to restrict the network from 
presenting their number). The telephone number (or associated 
name) is displayed on the ringing featurephones.  
The CDS information is also shown if the extension is equipped 
with a standard phone which supports the CDS service. 
Your telephone number will also be presented to persons you 
call, unless you restrict your number from being presented. 
The CDS store automatically stores information relating to 
unanswered calls to the system (answered calls can also be 
stored).  The information stored is the caller telephone number, 
and the date and time of the call.  Information is not stored for 
calls that withheld or unavailable numbers. When a new record 
is received and the memory is full the oldest record is discarded 
from memory. 
The CDS Store can be allocated as one central store of data on 
calls received. This store alerts extension 20 (default), by 
means of a display prompt, that new calls have been stored. 
You can also programme all 4 extensions to store up to ten 
numbers each.  
To examine and redial stored caller numbers  
Select ‘Missed Calls - Personal’ to examine the numbers in the 
personal store of your featurephone.
