Rainbow Connector for Microsoft Teams #

What it is and what it’s for #

Rainbow Connector for Microsoft Teams allows the use of the institutional phone line directly within Microsoft Teams, enabling users to make and receive calls using their university number, while fully integrating with the Teams environment.

The service includes key telephony features (VoIP softphone, call transfer, conference, forwarding, voicemail, call history, and contact directory) and is integrated with Microsoft Outlook through an add-in to initiate calls from emails or contacts.

It also provides presence status synchronization: during a call or a meeting on Teams, the status is automatically updated on Rainbow (for example, “Busy” or “Do Not Disturb”).

How to enable it #

To use Rainbow Connector, it is necessary to install the app in Microsoft Teams and verify the integration with Microsoft 365 within Rainbow.

1. Access the App section in the sidebar.
   
2. Search for Rainbow Business Telephony and select the official app.

5. Once completed, the app will be available among your personal applications in Microsoft Teams.
6. To keep the app always highlighted in the Teams sidebar, click on the three dots ... in the sidebar, find Rainbow Business Telephony, then select Add to pin it to the menu.

Frequently Asked Questions #

I am not receiving the confirmation email #

• Check the spam or junk folder.
• Ensure that you have correctly entered your institutional email address in the format a0****@unipi.it.

The application freezes or does not open #

• Restart the device.
• Uninstall and reinstall the application.

How to avoid receiving calls? #

To avoid receiving calls, set your status to Do Not Disturb within the application. This way, incoming calls will not be forwarded to the device.
For the caller, the line will appear busy. Received calls will still be visible in the call log, so you can return the call later if needed.
