its an alarm dispatch centre for many alarm companies. its not telemarketing or scams

SDI is an alarm monitoring centre in New Westminster.  Received several calls from them over the past few months of alarms going off.

this is an alarm monitoring call centre for BC alarm companies like Atlas alarms, they only call numbers on call-out lists - so best to answer this call since it may be a trouble alarm with your system.

Got a call from this number at midnight?  Don't answer

I get calls from this number several times a mont and have called them to have my number deleted from their call list as I don't have anything to do with the companies they represent.  Still getting calls!!!!
