A call and a hangup here too.  Probably the auto loan place, and probably claiming some peripheral link to TD Bank in an effort to seem unprovably legit.  Either their wardialer is toast - and I wanna believe they bought it on the cheap - or they're using call-and-dumps to confirm a number is valid so they can either use it themselves or sell the confirmation to someone else.  Nothing we can do at this point, sadly, as telephones still permit anonymous contact.  Are we all ready for the next stage of voice communications evolution, to where strangers can't dial you without a confirmed digital signature?
