I have a convenient heuristic which I imagine is quite common. I have a cell phone with an area code from where I purchased it, but I have since moved, so all my local calls come from a different area code.
Calls from my area code of residence are almost never spam, while calls from any other area code, and especially my phone's area code, are almost always spam.
