I need to know of a way to block spoofed ID calls our CUBE. We recently received a flood of calls where the calling DN (based on the RTMT real-time data) is text, not a number. The "Restricted" and "Anonymous" calls we won't block, but anything else that doesn't use 7 or more numeric digits as a Calling DN needs to be blocked. Any help that will resolve this would be greatly appreciated.
