Prepaid telephone service with automatic number identification recognition

摘要

A prepaid telephone calling card service that uses ANI recognition of a telephone used to register an account for preauthorization of subsequent calls from the same telephone. The calling cards are purchased through retain stores and then registered with a service provider. Additional ANIs may be associated with the account for preauthorization of subsequent calls. Registration of the account is completed by a consumer following a series of voice prompts without the need for authorization or intervention by the company administering the prepaid calling card service.
