Service Summary

This is an interim offering until a new telephone solution is selected.

MS Teams Calling Plans were originally made available as part of a pilot project testing a softphone solution. Calling plans are now available for all faculty and staff. Calling plans add several features for users, including the ability to place external calls via the MS Teams application, using your Mason phone number.

MS Teams is available via web browser, desktop application, and mobile app.

*International Calling Plans are not currently available.

Key Features

  • Presence
    • Presence is updated in real-time on the web and desktop versions and based on user activity (Available, Away), Outlook calendar states (In a meeting), or Teams app states (In a call, Presenting).
    • If there is no icon, the person you're trying to reach may not use Teams and may not know you are trying to reach them. If they appear busy or away, you may want to consider leaving a chat message instead.
    • Keep the MS Teams app open during your workday, so you don't miss calls and messages.
  • Voicemail
    • Voicemail is turned on by default.
    • You can configure your voicemail and additional answering rules under “Settings” -> “Calls.”
    • You can retrieve voicemails under the “Calls” tab; A copy of the recording and transcript is also sent to you via email. If you delete the voicemail from either location, it will be removed from both.
  • Collaboration
    • Tell your colleagues! This works best when more of your colleagues are engaged.
    • Start using it more often for 1:1 or small group collaboration.

Keep in Mind

  • Some new features require an update and may become available to users over time. Your colleagues may see certain features before you do (or vice versa).
  • Not all features you see in the MS Teams articles are available in our environment. Certain features may not be available based on our licensing or have been disabled for security reasons.

Getting This Service

To request a calling plan be added to your MS Teams account, please contact your Telecom Coordinator.

Once converted, your personal line will no longer be associated with your Avaya desk phone. Do not attempt to make calls from the Avaya desk phone unless it has multiple lines on the device. You will not receive calls to your personal line on the desk phone.


All faculty and staff for personal numbers (only). Requests for lines answered by multiple people, or call queues, are not being processed at this time.

General Requirements

Your device needs to have a speaker and microphone. It is recommended that you use a headset for improved audio quality and privacy. A webcam is ideal for a more collaborative and engaging experience.


  • Contact your Telecom Coordinator if you need to make changes to your phone service.
  • Contact the ITS Support Center if you need to report a problem or need more information about MS Teams.  


This service is available 24/7, excluding planned outages, normal maintenance windows, and unavoidable events. Maintenance windows are Sundays from 7 to 11 a.m. but may be extended to 2 p.m., if needed. If maintenance is required outside of these hours, it will be announced on the Alerts & Bulletins page.


All users of the George Mason University network must adhere to University Policy Number 1301: Responsible Use of Computing.

The University telephone system is available to conduct university business. University Policy Number 2204: Telephone Use applies to all university faculty and staff, including wage employees and contract employees, who have access to the university telephone system and/or who have been issued a university cellular telephone. 

Additional Information

Mason is working to select the next telephony solution. This is a project that will span several years. There may be changes or interruptions to this service as we get closer to implementing a more permanent solution.

While not recommended by ITS, please contact your Telecom Coordinator if MS Teams will no longer serve your needs for placing/receiving calls and you would like to resume using your Avaya desk phone. ITS will accept requests from Telecom Coordinators to port phone numbers back to physical desk phones in two waves. Requests will be accepted until Wednesday, September 8, for Wave 1 or Wednesday, November 3, for Wave 2.
