phone calls start teams meetings

I have an issue with the iphone phone app.

This is what happens:

1). I open the phone app.

2). I browse to contacts, find the contact and choose "call mobile".

3). It open the microsoft Teams app.

It used to open the Zoom app, so I removed the zoom app, then it started opening the teams app.

Is there a reason for this? I have to click on the phone number instead of the call icon. I just want to make a phone call to the person with the call icon in the phone app. Is there another way to fix this?

Thanks
