The problem here is the ability to spoof caller ID. This should not be possible. Regulations set up the phone system, regulations need to make this change. I don't care what excuse anyone has, don't care about your stupid PBX or any of that. Caller ID should be mandatory and reliable.
Having said that, always assume someone calling you is a fraud. If your "bank" calls you, tell them you'll call back and don't call a number they provide over the phone or in caller ID. If you can't find a reliable number to the bank, drive over there. The bottom line is that you can't trust anyone who calls you.
