this number keeps popping up, don't they have regulations about harassing phone numbers?

Got a call from this number, but I didn't hear anyone. Believe it was a telemarketer

Been getting calls from this number for a few days. No one ever on the line & only busy signal when called back.

I got a call from (905) 695-5520 and when I picked up the receiver, no one answered. I think the phone company should aggressively stop this phone harrassment, because I notice that many people have been harassed using the phone company.

March 24,2008, 2:45pm. Rec'd call from this number. Said it was Amir from Rogers. Heavy static like calling from cell phone. Called number back, just got beeping

Called Allstream. Turns out they are the provider of the line but not the main telco that sold them the line. Thinktel Communications sold them the VoIP line and that company resells it again across the internet. Talked to Thinktel and they are taking the customer down.
