Overview:
Starting February 20, 2023 some U of I telephone lines will require 10 digit dialing for both internal and external calling. If you are using a standard Cisco phone on your desk using 5 digits dialing to reach someone and it doesn’t work try using their full 10 digit phone number including the 8 to dial out. The list of prefixes for the various U of I location can be found below.
This article aims to describe the functionality provided in the University of Idaho's phone system, and how to properly dial both internal and external numbers from a campus phone.
