Zulu Softphone: How to Use the Software (including signing in/out and basic functions)

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 softphone 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.

Sign In to Zulu

  1. Log in with the following information:

    1. Username: username@carlpbx.its.carleton.edu (ie. fschiller@carlpbx.its.carleton.edu)

    2. Password: your normal Carleton password. 

  2. Do not change the port number below the login info.

  3. Click Login

If you do not have a Zulu account yet (if you go through the set-up phase and cannot connect), please submit a request to the ITS Helpdesk

Signing out of Zulu

If you are viewing your Zulu window while logged in and able to take calls:

  1. Click on the 3-line menu in the top left of the Zulu Softphone window, up near your name
