Abstract
A communication network is disclosed that uses voice authentication to provide call control. The communication network includes a call control function, a voice collection system, a voice authentication system, and a permission system. The voice collection system collects voice samples of a first party during the call to a second party, and transmits the collected voice samples to the voice authentication system. The voice authentication system compares the collected voice samples to stored voice samples to determine the identity of the first party. The permission system determines whether the first party is authorized for the call based on the identity of the first party. The permission system generates results based on the determination and transmits the results to the call control function. The call control function then processes the results, and interrupts the call if the first party is not authorized.
