CSUSB is in the process of replacing the traditional phone system with Microsoft Teams Phone.
Employees will be migrated to the new system during Fall 2025. Info regarding the migration and updates can be found below.

How To Use
There are different types of features available depending on the type of phone service.
What To Expect
Your desk phone is becoming Teams Phone

Your primary phone will now be on your Microsoft Teams Desktop app. Instead of a physical desktop phone, you will make or receive calls on a laptop, desktop, or (optionally) a mobile device with Microsoft Teams installed.
The calling experience works just like a Zoom or Teams meeting, but without the video.
- All Employees (MPP, Staff, Faculty) will be automatically enrolled in the bundled Voice and Data service. They will retain their current telephone number, or, if they don’t already have one, a new number will be assigned automatically.
- Any current desktop phones will be deactivated. Department Offices and Call Centers will be provided a new physical phone that connects to a Team in your Teams app. Physical Teams phones are in limited supply. Our campus has a software-first approach to Teams Voice services.
When
Your department's migration will occur on a specific date between October 18 and December 9. A detailed schedule will be provided to department heads.
