Some providers send an ANI that has nothing to do with the actual caller, and some allow it to send nothing at all. See http://www.oldskoolphreak.com/tfiles/voip/voipani.txt
I have noticed spoofing of 8 numbers as well. how do these get through the phone system, can't they detect ANI being bad at the source? I used to work for a company where we logged our workers on and off shift; rent a cop; based on the ANI data from the phone call. So I am really curious how this isn't blocked by entry into the system.
