Abstract: A computer-implemented method for validating the origination of an incoming customer call on a wireless communication network may include receiving a SIP invite message at the wireless communication network when the call is initiated, determining whether the SIP invite message includes one or more indicators indicating that the call originated within the wireless communication network from a device with a SIM registered in the wireless communication network, and writing a classification code to a database indicating that the call is validated if the SIP invite message includes the one or more indicators. The method may further include receiving the call at an agent computer device with caller identification information, querying the database via the agent computer device according to the caller identification information to obtain the classification code of the customer call, and suppressing a step used for call authentication if the classification code indicates that the call is validated.
