Same with me. Have had this number on my home phone (did not leave message) and cell. Probably a telemarketer, even though I am on National Do Not Contact !!! Grrrrr....
This is a fraud campaign currently active in Canada using a series of Iristel VOIP numbers. The objective is to obtain your credit card number and drain your account.
If you attempt to "opt out" your number will be confirmed as live and added to a suckers list for repeated future calls.
