Zulu Softphone Introduction

Tags Zulu


A “softphone” functions as a phone, but operates on your computer without a physical or “hard” handset or desk phone. Zulu is the software application used for making and receiving calls from your computer.

NOTE: Unlike a physical phone, which is always ready to take calls, a softphone will only work if the software is open.  You will need to open the software every day to make and receive calls.


Download Zulu from the K1000

Zulu has been configured for use at Carleton and must be downloaded from the K1000 Software Center.  Please do not download Zulu from the company's website.

  1. Make sure the VPN is on
  2. Go to k1000.carleton.edu
  3. Log in using your Carleton credentials
  4. Click the big blue Want Software? Go to Downloads page button in the Quick Actions area
  5. In the Search box in the upper right type Zulu
  6. Click the version of Zulu that matches your Operating System (macOS or Windows)
  7. Make sure that your computer is selected properly under “Device to install software on” and click “Run Now”
  8. At this point the install has been initiated - it may take a few minutes for it to complete on your computer.  You will likely see notifications when the install has started and when it has completed. (If you are prompted that there is a newer version of the software available you should install it. It may ask if you want to install it "just for you" or "anyone using this computer" and you should choose "just for you")
