Use FaceTime with the same Apple ID?
You can add another email address for FaceTime in your iPad:
This will allow you to call your iPad uniquely with this id.
Similarly, you can add another email address to your MacBook Pro's Facetime:
You have only on apple id, but do you have several emails ? In this case, you can add on your Macbook or your iPad another email address on which you will be call on Facetime.
For example : Your apple id account : [email protected] To call to your iPhone, use your phone number. To call to your iPad, use your apple id email. To call to your Macbook add a new adress in FaceTime preferences :
Hope this helps !
