Incoming call display setting controls whether the original caller number or the Cid number is shown as the caller number in calls coming in through the Cid number.

Using the Cid number is handy for e.g. personnel handling customer calls from their personal mobile phones: when they see a call coming in through the Cid number, they can answer in a different way than in calls coming directly to their mobile numbers.
