Ringer Device
You can use either or both the speaker and the headset as the ringer devices. You can configure which ringer
device to be used when receiving an incoming call. For example, if the ringer device is set to Headset, ring tone will
be played through your headset.
If the ringer device is set to Headset or Headset&Speaker, the headset (either a wired headset, Bluetooth headset
or USB headset) should be connected to the IP phone and the headset mode also should be activated in advance.
The USB headset is only applicable to T57W/T54W/T53W/T53/T48U/T48S/T46U/T46S/T43U/T42S/T42U/T41S
phones.
You can press the HEADSET key to activate the headset mode. For more information, refer to the Yealink phone-
specific user guide.
It is not applicable to CP920 phones.
