Dialing 911

There are two ways to reach 911 from the Cisco Phone:


  1. 911
  2. 9911


If you dial one of these by accident, please stay on the line and tell the 911 operator that it was a mistake, and then contact the front office immediately.


*If you dial 911 or 9911 the telephone system will call the front office and tell them that your extension has dialed 911 or 9911.
