A computer implemented method and system for routing a call based on characteristics of call data are provided. The method may include: receiving or retrieving a first data set representing a first set of plurality of call features relating to an on-going call from a database; generating, using a machine learning model, a suspiciousness score of the on-going call based on the first data set, the suspiciousness score indicating a probability of the on-going call being a fraudulent call; routing the on-going call based on the suspiciousness score; displaying the first suspiciousness score on a graphical user interface; continuously receiving or retrieving a second data set representing a second set of plurality of call features relating to the on-going call from the database; updating the suspiciousness score of the on-going call based on the second data set; and displaying the updated suspiciousness score on the graphical user interface.
