Cisco Desk Phones

Overview

A Cisco VoIP desk phone is the standard physical telephone used across the district. It plugs into the campus data network rather than a traditional phone line, and it works on its own without a computer. This article explains what the desk phone is, which models are deployed where, and what each one is best suited for.


What a VoIP desk phone is

VoIP stands for Voice over IP, and IP stands for Internet Protocol — the same networking protocol computers use. Cisco VoIP phones are effectively small networked computers. Instead of a dedicated telephone line, they use the district data network, which is configured to give voice traffic priority over ordinary data traffic.

Because of this, your desk phone shares the network cable that used to go directly to your computer. The blue cable from the wall goes into the phone, and a second black cable runs from the phone to your computer. This is normal and intended.  See Troubleshooting Your Desk Phone for what this means day to day.

What the desk phone does well

  • Multiple lines on one device. If you answer for a manager, a department main line, or a shared line, the desk phone shows each as a separate line button.
  • Speed dials. The bottom three buttons to the left of the display can be assigned as speed dials, and you can create up to 99 numbered speed dials in the Self Care Portal.
  • Busy Lamp Field. You can see at a glance whether a colleague whose line appears on your phone is currently on a call. The soft phone cannot do this.
  • Call park. Put a call in a numbered parking slot and pick it up from any other Cisco phone in the district.
  • Emergency broadcast. Desk and wall phones receive Informacast emergency broadcast messages through the phone speaker. These override volume and Do Not Disturb settings.
  • Independent of your computer. If your computer is off, restarting, or having problems, your phone still works.

What the desk phone cannot do

  • It does not travel with you. If you work from another location, you need to forward the line, use Single Number Reach, or use Jabber. See Working Remotely with Your District Phone.
  • Instant messaging, chat, presence and one-to-one video are not on the phone itself — those come from the Jabber application on your computer.
  • Hands-free headsets are not provided with desk phones. Most Poly (Plantronics) headsets work with Cisco VoIP desk phones, though some models require an adapter.
