How to Put Campus Phones in Do Not Disturb Mode

REMINDER: DO NOT UNPLUG PHONES!

The phones have a "Do Not Disturb" feature that will send all incoming calls directly to voicemail. Please see the below pictures to locate the button to activate this feature, depending on the type of phone in your testing location. The red arrow with the black border indicates the button on the phone. Simply press the button to activate. The light next to the button will glow red, and the phone will display DO NOT DISTURB. Be sure to deactivate this feature by pressing the button again once your room has finished testing.

Basic Phone with the location of the DND button
Admin phone with the location of the DND button
