BT Quartet 1500 - Manual (Page 25)

The second caller is only charged
from the second you answer, not
while they are waiting to be
connected.
Call Waiting
Providing you have subscribed to your network provider’s
Call Waiting service, you will hear a soft beep every
5 seconds if an incoming call arrives while you are
already on the phone. This beep is not audible to the
person you are speaking to. The second caller’s number
(and name if stored in the phonebook) will appear on the
handset display.
Instead of the engaged tone, the second caller will hear
an announcement asking them to hold the line.
