2nd call from this number and no one there.  Would appreciated knowing who was calling

they can call because fall under the research catagory thatand thus are not considered telemarketers

I live in New Brunswick now and I received a call from this number in Sask on my caller ID.  I was not home at this time and lived in Sask years ago and thought it might be an old friend calling but i looked up your site so now dont have to worry if the call was important. tks.

I think all this flow of numbers, can only come from the phone company itself, as you see them changing phone numbers, and there are a great many phone numbers of them. Who can afford himself to have so many phone numbers, if it is not from a phone company itself, or from a few of their employees.

Have a look at the List of reported phone numbers:
