How to invite user to a teams meet by ringing them on teams?

Hello @a-s,
Thank you for your inquiry about your Teams app development issue!

Creating an app that generates Microsoft Teams meeting links and invites a specific user to the meeting, making their Teams app "ring" directly, is indeed possible using the Microsoft Graph API.
You can use the onlineMeeting resource in the Microsoft Graph API to create an online meeting. This API allows you to create a standalone meeting that isn't associated with any event on the user's calendar.
To invite users to the meeting, you can use the AddParticipants method of the Microsoft Graph API. This method allows you to add participants to an existing meeting.
To make the Teams app "ring" the user directly, you can use the call resource in the Microsoft Graph API. This resource allows you to place a call to a user, which will make their Teams app ring.

Hi a-s,

Thank you for reaching out to Microsoft!

Here are some resources and guidance on how to generate Microsoft Teams meeting links using the Graph API and invite a specific user to the meeting.

You may use the Calling and Meeting Bot functionality as shown in the article below.
