Hello Pdrummond2015,
Thank you for using Apple Support Communities.
It sounds like in your Contacts app you are seeing only an option to call people using Teams, but you want to know how to call people using FaceTime instead. If you touch and hold the Teams option in the contact, does it show a window giving you an option to select from Teams or FaceTime? Learn more about gestures on the iPhone here: Learn basic gestures to interact with iPhone.
You can also make FaceTime calls directly from the FaceTime app rather than from contacts. Learn more here: Use FaceTime with your iPhone, iPad, or iPod touch.
We hope this helps!
