Here in the USA, you may be violating "do not call" lists from people who do not want unsolicited sales calls on any of their phones.
I believe it would also be mostly a waste of your time, as most people would probably hang up before you got very much information mentioned.
For cold marketing, you might be much more successful to place SFI and/or TripleClicks cards or flyers under windshield wiper blades in store parking lots. Or post flyers on notice billboards inside some of your local cards. When cold marketing in your local area, give consideration (and think of your safety) to including your phone number.
