Note
Using a Headset
You can connect an analog or USB headset to your phone and use the headset to place and
answer calls. If you want to use the analog headset, you require an optional headset
YHS32/YHS33. The SIP-T42G/T41P IP phones do not support USB headset. For more information
on how to use your USB headset, see your USB headset documentation from the manufacturer.
You can also pair and connect a Bluetooth headset with your
SIP-T48S/T48G/T46S/T46G/T42S/T41S IP phone. For more information, refer to Pairing and
Connecting the Bluetooth Headset.
Note
Using an Analog Headset
If you want to use the analog headset, a headset YHS32/YHS33 is required.
We recommend that you use the accessories provided or approved by Yealink. The use of
unapproved third-party accessories may result in reduced performance.
Your system administrator can disable the headset feature. Check with your system administrator
to find out if it is available on your phone.
