I was testing out my U.S. Skype number while overseas and called myself from an international phone. When I dialed, this number popped up on my Skype screen instead. I answered it and talked to myself. I did call myself again to verify, but my full international number showed on caller ID the second time.
I'm wondering if this is a Skype switchboard that receives international calls and diverts them to local phone numbers. That could explain why a lot of spam calls come in.
