The method comprises receiving a first call origination message from a communication network by a computer system, wherein the first call origination message comprises an automatic number identification (ANI) storing a first phone number, determining by the computer system that the first phone number is not associated with an originator of the first call origination message, and responsive to determining that the first phone number is not associated with the originator of the first call origination message, dropping the first call origination message by the computer system and not answering the associated call, whereby the enterprise call center reduces its vulnerability to call origination spoofing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Authentication of phone call origination","description":"A method of authenticating a call origination directed to an enterprise call center.
