"This is an important announcement from Hilton Hotels.  Your telephone number was randomly selected to receive a complimentary stay in one of our 5-star hotels.  For further details, press 1 now."

An obvious scam.  The sad thing is that they spoofed a local telephone number.  I usually don't answer calls from distant area codes, but this call could have come from a neighbour so I answered it.

They also called yesterday from 613-832-9085.
