Note: The primary phone number cannot be unassigned from the Auto Attendant. To release the main number, you need to swap it with another spare phone number on the account. Released numbers can be later assigned to a user, a Hunt Group, or any other object on the account. Toll-free numbers cannot be used as primary users' numbers.
