Abstract: One example method of operation may include receiving a call message intended for a call recipient, removing one or more portions of call message data included in the call message, identifying one or more of a trunk group and an entry point associated with the received call message, adding one or more of a trunk group identifier (TGRP) and a universally unique identifier (UUID) to the call message to create a modified call message, and forwarding the modified call message to a destination network associated with the call recipient.

Abstract: An example method of operation may include one or more of identifying an outbound call placed by a mobile device subscribed to a protected carrier network, determining the outbound call is destined for a destination telephone number that was stored in a call history of the mobile device, determining the destination telephone number is a scam call suspect telephone number based on one or more identified call filter parameters associated with the destination telephone number, and forwarding a scam call notification to the mobile device while the outbound call is dialing the destination telephone number.

Abstract: One example method of operation may include identifying call data associated with a received call, identifying call parameters from the call data, and the call parameters include one or more call routing parameters associated with call routing of the call and one or more call session parameters associated with a call session of the call, assigning weights to one or more of the call routing parameters and the call session parameters, determining a scam score for the call based on a sum of the weights applied to the call routing parameters and the call session parameters, and blocking the call when the scam score is greater than or equal to a predetermined threshold scam score.

Abstract: One example method of operation may include receiving one or more data messages, identifying calls and corresponding call data from the one or more messages, identifying call parameters from the call data, applying a call activity filter criteria to the call parameters to identify a suspect sub-set of the call parameters which indicate an elevated likelihood of call scam, forwarding the call parameters and the suspect sub-set of call parameters to one or more call data tables, and assigning one or more scam designation threshold scores to the suspect sub-set of the call parameters in the one or more call data tables.

Abstract: One example method of operation may include identifying a call destined for a mobile device, querying a number portability database for call routing information, receiving one or more of a location routing number assigned to the mobile network operator and a location routing number assigned to the mobile virtual network operator, forwarding a call message associated with the call to a session border control device operated by the mobile network operator, and determining whether to route the call to a mobile network operator subscriber or a mobile virtual network operator based on whether the location routing number is assigned to the mobile network operator or the mobile virtual network operator.
