Method and apparatus to validate a subscriber line

摘要

Automatic number identification (ANI) data or billing telephone number (BTN) data associated with a subscriber account of a telecommunications network is obtained. Thereafter, first reference subscriber data associated with a subscriber is obtained. The first reference subscriber data is different from the ANI data or the BTN data. A first database location is accessed using the ANI data or the BTN data to determine second reference subscriber data. A second database location is accessed using the ANI data or BTN data to determine that the subscriber account associated with the ANI data or BTN data is billable. The first reference subscriber data and the second reference subscriber data are compared, and the identity of the subscriber verified if the first reference subscriber data corresponds to the second reference subscriber data.
