BT Calling Features 47
With the ring back feature you 
can get an automatic call back 
from an engaged number. No 
need to dial a busy number over 
and over again. Just dial 5, wait 
for a confirmation message and 
hang up. Your phone will keep 
trying the busy number for up 
to 45 minutes.
Call Waiting lets you know if 
another person is trying to call 
you while you’re on another 
call. If a second caller rings, you 
will hear a beep in the handset 
earpiece. If you’ve subscribed 
to Caller Display, the display will 
show the caller’s details as well.
