Your administrator sets up the priorities that you can use and determines whether you need special sign-in
information.
When a high-priority call rings on your phone, you see the priority level on the phone screen and the call
appears at the top of the call list. If you are on a call when a high-priority call comes to your phone, the
high-priority call preempts the current call and you hear a special preemption ringtone. You should hang up
from your current call to answer the high-priority call.
If you have turned on do not disturb (DND), a priority call will still ring your phone with a special ringtone.
When you are on a high-priority call, the priority of the call does not change when you:
Put the call on hold
Transfer the call
Add the call to a three-way conference
Use call pickup to answer the call.
