Well, that was strange

 Got three scammy robo-calls today (on my landline) from the same number. Okay, that's not strange - pretty much par for the course. The weird thing was that according to my caller-id, all three calls were FROM ME. I get lots of robo-calls with numbers obviously spoofed to look like they are from my local exchange. But this is the first time I've seen the entire number spoofed.
