The method may include receiving a transmission of the incoming call in a user device. The method may include determining the incoming call originates from an area code of a telephone number associated with the user device. The method may include determining call information associated with a telephone number is stored within a database. The method may include determining at least one previous call from the telephone number has a call duration that does not satisfy a user preconfigured call duration threshold. The method may include determining the at least one determined previous call satisfies a maximum short call duration threshold. The method may also include determining a previous call frequency count satisfies a user preconfigured frequency threshold. The method may further include displaying the incoming call and an incorrectly dialed call notification on a display screen of the user device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Area code and call duration-aware call screening","description":"A method for screening an incoming call is provided.
