Abstract
Systems and methods are described that provide a phantom mobile telephone number that is assigned by the mobile telephone service provider, for business customers and/or customers subscribing to the service. Upon receipt of the phantom mobile telephone number at the mobile service provider's internal call routing system, the call is associated with a preexisting landline number assigned to a business. The mobile telephone call is forwarded to the preexisting landline telephone number and is not charged airtime minutes.
