(905) 674-6214 has been calling for many days, was not home to pickup, but no message was left.before this unknown number calls, we'd say no to a duct cleaning offer (can't remember, but was a different number), may be related. don't really know.we took the expensive call-display was due to the increasing number of unsolicited calls last year, all from persons we don't know. its not a solution, but at least a first line of defense!could the phone company be behind these by providing phone numbers that cannot be *tracked to anyone,i mean, providing weapons to both parties on the battle field :(

Recived call and let it go to voicemail with no message being left. Called back and number was constantly busy, looks like the telemarketers have a new number.
