Caller ID Spoofing?

OK, someone has way too much time on their hands.
Remember the fake email pretending to be me earlier this week? Well now that same women is getting phone calls with my number coming up on the caller id. WTF?

Evidently this is not too hard to do. For a small fee, you can do that with any number. There are even websites set up to let you do it. So, once again. In this new age you want to verify who is talking to you or even trying to get ahold of you.
