They've been calling here all the time. I never answer - they never leave a message. However, last night they called and someone hummed a tune then whispered a bunch of stuff that we couldn't understand. So annoying. I wish an MP would address telephone solicitation "issues" in Canada with a true Do Not Call bill.
This number is for Iristel Inc. - described on Wikipedia as a Telecommunications - Voice Over IP industry.
I'm guessing that they're trying to sell a phone service for international calls.
