I called the number, it's a company called blu tone they are trying to sell you long distance and international phone plans. It's a bunch of Arabs don't support their cause, terrorists
I have been getting calls as well from this number (905-769-1183) for months. They also call using 617-555-6120 and 201-268-7961 and likely other numbers. As someone else mentioned it appears to be a company called "blue tone". They are selling long distance plans. They seem to be legit in that they have a website and are research-able on the net. I did talk to one of their reps once and got some details on the LD plan and rates. I checked them out and found they were not competitive in my particular situation, so I did not follow up and take one of their plans. Problem is they keep calling, they just will not take no for an answer or take a hint when you do not pick up their calls for the 100th time. Really annoying. Making me consider going back to passenger pigeons as a primary communication technology.
