Settings > Receiver and Headset > Headset Ringing

Headset Ringing
During headset operation (headset switched on), three types of call signalling are possible:
1. Ringing through the loud speaker (as for receiver operation)
2. Ringing through the loud speaker + the headset
3. Ringing through the headset
For the second and third operating mode, headset ringing must be switched on as described here. For the third operating mode, the ringer must also be switched off.
Proceed as follows:
Using COMfortel Set (page Settings/functions > Headset, check box Headset ringing)
Using the telephone (menu settings > headset > headset ringer)
