The campus building has 2 intercom systems; one on the front door and one next to the backdoor. When someone rings the doorbell of your appartment the Intercom will call your phone!

When you are called you will see a number starting with +33.
You can store it in your contacts as "my doorbell" so you recognize when someone rings the door doorbell.

You can speak to the person in front of the door and open the door by pressing * on the keypad of your phone! 

On the My Keys page you can see the number which we stored for you when registering your keys. You can update the phone number anytime on the My Keys page!
