Toll free: A telephone number that is billed for all arriving calls instead of incurring charges to the originating telephone subscriber (for example, 1-800 numbers in the US). Premimum rate: Numbers for telephone calls during which certain services are provided, and for which prices higher than normal are charged. Unlike a normal call, part of the call charge is paid to the service provider, enabling businesses to be funded via the calls. Shared cost: Premium country-specific phone numbers in the UK, Australia, Germany, Switzerland, France, Portugal, and the Netherlands. These numbers are charged at a higher rate than regular numbers, however call rates are generally lower since the cost is shared between the caller and the business receiving the call. Charges to the caller are typically the amount of a local phone call with the receiver paying the usage rate. VOIP: Voice over IP number, which is a real telephone number assigned to a user, but not to a specific phone line. Personal number: A number associated with a particular person, and may be routed to either a mobile or fixed line number. Pager: A number to send a message to a pager.

enriched_phone_carrier	The original carrier of the phone number Available for mobile numbers only
enriched_phone_success	Returns false if the enricher encountered an error, otherwise true.
