Hi @mohammadamer, have you tried getting the Teams meeting id through Microsoft Graph onlineMeeting? This way you may access to all the details of the meeting. Here is the documentation for the details, let me know if you need further assistance on this: https://learn.microsoft.com/en-us/graph/api/onlinemeeting-get?view=graph-rest-1.0&tabs=http

The meetingID from the teamsContext is not the onlineMeetingId but an encrypted version if the chatID
Yannick Reekmans figured this out once upon a time:

I could only give you answers dealing with JavaScript. Didn't try to refactor that to C#, yet. Even in my Visual Studio projects.
Would that help?

Here is a TeamsToolkit VisualStudio C# (backend) sample dealing with the teamsContext in TeamsJS SDK v2 in general:

And here one of my Teams meeting app samples dealing with the meetingID itself. That sample is nodeJS (yoteams) based but I hope you should be able to put the pieces together
