Do Not Disturb
Ever need some time when your phone isn’t ringing off the hook? You can set your phone to reject all calls with the Do Not Disturb function.
Press the DND soft key on a Yealink T21P phone while the phone is idle to turn the Do Not Disturb function on. You can turn it off again by pressing DND one more time.
Calls received during this time will be logged to your Missed call log in the portal.
