发明名称 CALLER ID CALLBACK AUTHENTICATIONI FOR VOICE OVER INTERNET PROTOCOL (VOIP) DEPLOYMENTS
摘要 Systems and methods are disclosed for authenticating caller identification in VoIP communication. A VoIP device receives an incoming call from an originating calling device; wherein the incoming call includes (1) a caller identification and (2) a unique identifier associated with the originating calling device. The VoIP device verifies that the caller identification in the received incoming call matches an entry in a trusted directory, wherein the trusted directory includes one or more entries of previously verified caller identifications. Upon verifying that the caller identification in the received incoming call matches a caller identification entry in the trusted directory, the VoIP device sends an inquiry to a unique locator associated with the matching caller identification in the trusted directory.
