Hey there stephbien,
Thanks for reaching out to Apple Support Communities. Congrats on your new iPad Pro. I understand you only want to get FaceTime calls on your iPhone and Iâll be happy to help with this.
One simple way to do what you want is go to Settings > FaceTime and turn FaceTime off. If you want to be able to use FaceTime on your iPad some of the time, you can go to Settings > FaceTime and look at the options under âYou can be reached by FaceTime atâ. On your iPhone, you can just have your number checked and on your iPad, you can just use your Apple ID. That would allow you to use FaceTime on both devices without getting the calls on both devices at the same time. You can read more about this here:
Use FaceTime with your iPhone, iPad, or iPod touch

Best wishes.
