Abstract: A system and method of verifying a caller identification utilizing a server that communicates with a computing device capable of monitoring communication networks for specific communications from an enterprise voice network. The server can push a spoof prevention contact list to user devices. Additionally, the server can receive notifications from the computing device in response to user inputs that allow match analysis to occur with the information in the received notifications. When a match is found, the server can send a notification to a user device to modify a contact name in the spoof prevention list stored in the user device. After a specified time, the contact name can be altered back to the original state. As an example, the contact name in the spoof prevention list may start out as “unverified call,” and be changed temporarily to “verified call” upon receipt of the notification.
