It's a rep. from SiriusXM Radio trying to have your satellite radio re-activated.  If you've recently bought a new car that came with a 3 month free trial of SiriusXM Radio, but had let it lapse, then these telemarketers call with the following three offers:

$89.99 for one year (with $15 reactivation fee waived).  Refuse this then you'll get $30 for six months offer.  Refuse this and you'll get a $0.99 cents for one month offer, but you have to give your credit card information.  I refused all three.

They will keep calling you until you pick up, though.  They have called my number a total of 10 times since 8/18/14 (today is 8/27/14).
