Because Caller ID can be faked or blocked.  Malicious Call ID does two
things for you.  First of all it marks the call in CCM's CDR records so
that the exact call record can be found easier in your CDR database.
Second, (assuming you have the proper trunks to the PSTN) it sends a
signal to the telco to mark their CDR records.  These steps will make it
easier to trace the malicious call back to the origin.
