Abstract
The technologies described herein are generally directed to modeling radio wave propagation in a fifth generation (5G) network or other next generation networks. For example, a method described herein can include, facilitating, by a first device, receiving a first communication directed to a second device from a third device associated with a first telephone number. The method can further include determining, by the first device, that the first communication comprises a reference to a second telephone number different from the first telephone number, resulting in a number discrepancy. Further, based on the number discrepancy and an analysis of the first communication, the method can further include preventing, by the first device, communication of the first communication to the third device.
