Caller ID showed "BREITENBACH GER."  Female caller claiming to be with YP (Yellow Pages) ref online listing.  Possibly due to some changes I made to our listing.  She started asking all sorts of questions about our business, which I was suspicious so answered them incorrectly.  Eventually I decided to put her on hold and when I came back she was gone.

Don't know why YP would be spoofing their caller ID, though.  Must have been a data miner looking for information to sell to scammers or other telemaggoters.  Number comes back to an AT&T mobile phone.
