Why is the name or number of a person not displayed during a call?

If the call was initiated from the mobile device while a Bluetooth® connection existed, it is not possible to guarantee that the number or name of the other party will appear on the Control Display. Otherwise, you should check whether the telephone book of the mobile device is displayed on the Control Display and the contact concerned has been transferred correctly and completely.

If it’s an incoming call, this is often because the caller has enabled the Withhold Number function on their mobile device.
