Microsoft Teams has been growing in capabilities, and this is allowing many possibilities in terms of more flexible voice communication on and off campus. Oftentimes, needs arise where you may need to take work-related calls; however, you're not at your desk and you don't want to use your personal cell phone number to take the call. Microsoft Teams can fill that gap.

Teams allows you to make or take calls from the application or app itself rather than your traditional Cisco desk phone. This means that you can call from your computer, smartphone or tablet and it will appear as your TMU number to the person you are calling. In addition, you can also opt-in to receive calls to your computer or smart phone by filling out this form to Enable Teams Calling.

Preparing for Teams Calling

You will need to ensure that you have a microphone in order to make or receive calls in Teams. If you have a TMU-owned laptop, you have a microphone built in. However, if you are on a desktop computer, you will need to have a microphone to make calls. A webcam will work for this purpose. Smart phones will receive calls very much like a regular phone call and will utilize the built-in microphone and speaker system. 

Enabling Teams to Receive Calls


Note: In June 2020, it is planned to have all users enabled to receive calls in Microsoft Teams in addition to your office desk phone.

If you have not been enabled to receive phone calls in Microsoft Teams, fill out this form to opt-in: Enable Teams Calling. Once we enable Teams calling for you, you will be notified of the update. Please allow one full day for the update to take place.

Once this feature has been activated, calls will automatically start coming into Microsoft Teams and you will see the call notifications.

Controlling Notifications in Teams

By default, Microsoft Teams will ring all devices that have Microsoft Teams installed. You can control the notifications for each individual device to keep particular devices from ringing when you are called.

Controlling Notifications in Windows and macOS

Currently, you cannot customize call notifications on Desktop. The only option is to disable all other notifications by doing the following.
  1. Open Microsoft Teams
  2. Click your profile picture in the upper-right corner of Microsoft Teams
  3. Click Settings
  4. Click Notifications on the left-hand side of the menu
  5. Scroll down to Other > Notification Sounds and set it to the desired setting. The setting is saved automatically. You can exit the settings window.
Alternatively, you can set your status to Do Not Disturb, disabling all incoming notifications until your status is changed to something else.

Controlling Notifications in Teams Mobile

This applies to iPhone, iPad and Android phones.
  1. Open Microsoft Teams
  2. Select the Menu button (or swipe in from the left)
  3. Select Notifications
  4. Under the setting labeled Incoming Calls, choose to enable or disable the notifications using the switch on the right.
If you have any questions, please feel free to contact the IT Service Desk.

Current Limitations and Known Issues

As always, maintaining interoperability and features is an important aspect of introducing something new. The following is a list of limitations that we are either working to resolve or waiting on Microsoft to release:

  • Calls from other Teams users do not ring your Cisco desk phone. Due to limitations in Microsoft's phone system, when using Teams to call another user directly in the app (by using the call feature in chat, for example), or when you dial their full 10-digit number, the call only rings the recipient's Teams on their computer or mobile phone app. As a workaround, dial the person's 4-digit extension from within Teams using the dialpad. This will ring their desk phone. The one exception to this is if the recipient has had a Teams phone deployed to them.
  • Hold does not work as expected. After putting a caller on hold in Microsoft Teams, you are unable to resume the call. Until this is resolved, our recommendation is to simply use the Mute function until the call is resumed rather than the mute button. This is actively being investigated.
  • Call sound delays. Some users have reported that there are voice delays. This is not caused by Microsoft Teams. This problem is marked by frequent accidental interruptions and delays in responses. If you encounter delays like this, please contact the IT Service Desk. Please include the number that was called (or the number that called you) and the time of the call.
  • Silent voicemails. Some users have reported silent voicemails. This is not caused by Microsoft Teams, but rather when a call is transferred, there may be scenarios when the resulting voicemail is silent. This is actively being tested and investigated.
  • Infinite Ringing when busy. When a call to a recipient is in progress, a call to that extension will result in the line ringing infinitely until the caller hangs up rather than going to the recipient's voicemail. This is actively being tested and investigated.
