We also recommend referencing the Microsoft Teams Quick Start Guide and OIT's Microsoft Teams service page.
How accessible is Microsoft Teams?
Microsoft Teams can be very difficult and time-consuming for users of assistive technology due to inconsistent navigation requirements, multiple regions, unpredictable focus changes, quantity of content, and lack of structural cues. If you or a colleague uses assistive technology, alternative options listed on the Teams Accessibility page should be considered instead of relying on Microsoft Teams for communication.
Does Microsoft Teams work on a Mac or Linux machine?

Is it possible to get a recording or transcript of a voicemail forwarded to our CU Boulder emails?
Yes the standard voicemail solution integrates with CU Boulder email and sends an audio file and transcription to your email box. OIT's video tutorial on how to configure Voicemail covers this feature.
Will calls still work if I don't have an internet connection?
Does the phone still ring if my computer is off or it is after work hours?
How can I ensure my phone does not ring or interrupt me during a meeting or class?
There are several ways to do this. OIT recommends setting your status to Do not disturb. No notifications or calls will come through when your status is set to Do not disturb. Visit OIT's Change your status in Teams tutorial to learn how.
How can I silence Team notifications during times I need to focus and not be interrupted?
You can utilize the Do not disturb feature in the previous question, or edit your settings to not allow notifications when you are in a meeting. Teams pulls your calendar from Outlook, so you will need to ensure your calendar is up to date, as well as setting this notification. Visit OIT's Microsoft Teams - Change Notifications tutorial and scroll down to Meetings and Calls to set this up.
Please note: OIT is aware of a known issue affecting notfications. At this time, changes to notification settings are not working to silence calls. If you need to silence all calls, use the Do not disturb feature.
Will silencing notifications and calls in Teams silence all other calls on my personal cell phone?
No, changing your notification settings in Teams only affect calls that go to your university number using the Microsoft Teams application. Personal calls are not affected by these settings, and you can adjust notifications for them in your phone's settings.

Transition from Cisco VoIP
Why did the campus transition from Cisco VoIP phones to Microsoft Teams?
In order to address hybrid and remote work modalities for CU Boulder, our phone service needed to adapt to provide flexible and agile communication functionality in ways that traditional physical phones, like the Cisco VoIP phones, just don't do well.
The convergence of the unified communications landscape, coupled with the university's investment in the Microsoft suite of tools, presented the opportunity to address our needs with Microsoft Teams.
With the campus voice service hosted on Teams, our phone service continues to provide traditional phone features, but also allows for seamless integration with Teams features like Chat, Calendar, Files and more. And because you can use Teams on your desktop, laptop or mobile devices, the experience is consistent and easy-to-use no matter if you are on-campus, working remotely or moving between both.
When did the transition happen?
The transition away from Cisco VoIP began in fall 2022. The conversion of phone numbers to Teams took place incrementally by organizational groups (e.g., departments, schools, colleges).
How were telecommunication liaisons involved?
OIT's Voice Services team provided telecommunication liaisons with a spreadsheet containing their department's information. They were asked to verify the information and submit any changes by a specific date.
What was the process for replacing a Cisco phone with a softphone (Teams)?
The user's Teams extension was activated on the Tuesday of their migration week. Once activated, users were able to place and answer calls from their desk, a personal cell phone, or anywhere they logged in to the Teams application using their current campus phone number. During the migration week, a technician came to their office or work space to remove the Cisco physical phone.
When the technician arrived, they followed these steps:
- Located the Cisco physical phone and verified the extension.
- Unplugged the data cable from the Cisco physical phone and plugged it directly into the user's computer or docking station.
- Removed the physical phone.
The process typically took less than 5 minutes.
What was the process for replacing a Cisco phone with a new physical phone?
Between Tuesday and the following Monday of the user's migration week, a technician came by the user's office or work space to replace the Cisco physical phone with a new physical phone.
When the technician arrived, they followed these steps:
- Located the Cisco phone and verified the extension.
- Unplugged the data cable from the Cisco physical phone and plugged it into the new AudioCodes physical phone.
- Waited for the AudioCodes physical phone to boot up and register, then tested the functionality.
The process typically took 5–10 minutes.
Did the original phone numbers remain active after the transition?
Yes, campus extensions remained the same.
When was the calling feature enabled in Microsoft Teams?
The calling functionality in Teams was enabled when the user's phone number was transitioned to Microsoft. Users received several emails in the weeks prior to the transition and again once it was complete.
How did the change impact call centers?
Call centers were migrated to a Microsoft Teams-compatible application after the first phase of phone migrations was complete.
What happened to Cisco conference units?
Any Cisco conference units that were purchased by the department were replaced with Teams-certified equipment.
What happened to physical phones in common locations, like classrooms and break rooms?
OIT replaced phones in places like classrooms, labs and other areas that require a phone for safety reasons.
