Same thing here in Oregon.  Called once and directly hung up before I could answer it.  Called right back.  I didn't answer it and they left no voicemail.  

Called once and didn't answer when I picked up. Portland Oregon

I answered this time.  They are legit.  It is for a free renewal of a technical magazine subscription.  

I am embarrassed to admit when I answered I was ready to be rude, but soon realized it was they already had all my info from my subscription.  "This call is being recorded for quality purposes." "Do you still want to receive XXX magazine?"  Yes.  "Your email is xxxx..xxx. Is that still correct?"  Yes,  "I have your address as xyz street.  Is that still correct?" Yes "Do you still specify XYZ equipment ?"  Yes.  Thank you for your time."  

They called again today.  I answered this time.  The wanted to 'confirm' my address so that they could send me a subscription to a magazine.  LOL this is so not legit.  Nothing that you really want to receive from a telemarketer is going to be free.

They called 3 times in a row and I explained we were not interested. Rude lady.
