Bingo! finally figured out who is spoofing the local pediatricians office.
I've gotten at least a half a dozen private numbers with names that lead to the doc's place.
But this one after digging leads to:
http://www.ahepa4.org/ So political organization. Apparently from Philly, PA
Maybe they have local members who are letting them use their home phones. - I doubt it.
But that is why even if there is a name in the ID I don't answer the phone if I don't know who it is.
And of course there was no message.
