Pre-connection call authentication within a telephony network |
摘要 |
A method for providing call authorization within a telephony network can include receiving a telephony connectivity request for establishing a telephony voice channel between the originating device and a receiving device. The specified receiving device can be determined and receiving device specific information that includes an authorization requirement can be accessed. A connection between the originating device and the receiving device can be established responsive to whether the authorization code satisfies the authorization requirement.
