You can change your headset ringtone behavior through the Preferences menu on the Cisco IP Phone 7800 and 8800 Series.

The setting saves to the phone and applies to any Cisco headset that connects.

If you use the Cisco Headset 560 Multibase, you need to press on the base for your ringtone changes to take effect.

By default, your phone follows the behavior of the phone ringer settings. Select On if you want to hear the phone ring whenever you have an incoming call. Select Off if you don't want to hear any ring through your headset when there’s an incoming call.
