BT 1020 - Manual (Page 17)

Hi Def calls
Your BT Hub phone is designed with High Definition Sound
(Hi-dS™) capability.
If somebody using a BT Hub Phone (or other Hi-dS™ capable
device) calls someone else using a Hi-dS ™ capable device,
then the call will automatically set itself to the best call
quality using the Hi-dS™ call quality feature. Hi-dS™ works
automatically, so you don’t need to do anything to enjoy
high-quality sound.
You won’t get Hi Def sound from the phone plugged into the
back of the hub though as this is only available on devices
which carry the Hi-Def™ logo.
Multiple calls
No more hogging the phone… with BT Broadband Talk you
can make more than one phone call at the same time.
You can have 2 calls going on at the same time via the BT Hub
phone handsets and a third call using a phone plugged into
the socket in the back of the hub.
