Abstract
A calling line authentication system and method are disclosed. The system comprises a communication network and a key server. The communication network receives a telephone number signal from a calling source attempting to access a secured service of a calling destination. The communication network identifies a directory number representative of the calling source and provides an authentication key to the key server when the directory number is one of a list of authorized directory numbers stored within the communication network. The key server provides the authentication key to the calling destination as an indication that the calling source has authorization for access to the secured service.
