I got a call from a number 4168406462, i answered and they did not respond so i hung up.. they call my house between the hours of 1 to 5 pm ALL THE TIME! Told them to stop calling they still call.. The number seems to be from a Toronto phone land line. They are most likely Scams.. i found out who they were by calling their number back turns out the company is Windows and doors.. they are complete scamers so if they do speak to you and advertise there company dont buy it.

YEP,  Another gypsys trying to sell you stuff

Suffering calls from them for the past 2 months. Requested to be taken off the call list, they still refuse to do so and are almost relentless. The call center number tracks down to a location on Younge street in Toronto. Their service provider is :
CALL NET COMMUNICATIONS
                            Type
                         CLEC
                            Location
                         TORONTO, ON  

here is the info on Call Net Communications

In other words, best assumed you have a Roger's number ("252" or the latter) and these guys work hand in hand with them, so your Service Provider is basically the one handing out your number to them. They get off on the blank phone calls calling it a "Diagnostic Maintenance Test", which is actually just an excuse to use a callbot and check your hours when you are at home to receive a call. After, which they shall proceed to personally harass you by sending out your number to a "Deluxe Windows and Doors"  

Here is their number and location with website.  

Deluxe Windows
25 Milvan Dr, Weston, ON, M9L 1Y8
(416) 740-4368

Feel free to start sending telemarketers their way.

Excellent work,  but if I could a point. If you have a fax, may I recommend everyone sending them fax's to there phone number ;-)

Great idea! Especially if you have a modem on a computer. You can keep sending them faxes tying up their line indefinitely. Unfortunately, that would also tie up your line as well, but it would send a message.
