I left a comment about this number a week ago and it called back again today on Saturday evening.  This is a market research company calling to ask opinion polls.  This was the first time anyone has ever been on the line.

We've been getting calls every night from this number.  I used to work for a telemarketing company way back.  They use a device called a Predictive Dialer (actually a computer) that dials numbers continuously and listens for the click when you answer.  If you don't answer, your number goes back into the database and it keeps calling.  When you answer and there are not enough salespeople working, you get just dead air.

There's software and hardware out there that 'zaps' the database by playing the "this number is not in service" sound when they call.  We haven't bought it yet!!

I receive this call every few days after 6pm, and today (Saturday) it came in early afternoon.Thankfully I run my own Trixbox (VoIP PBX phone system) and have simply added it to my blacklist, which never rings my extension and sends back the zapteller to the calling end. :-D

This number has been calling everyday around 6:30 p.m. for about 4 days. When I answer it there is no one there.  Called back and it didn't even ring.  I'm in Alberta.  Caller ID just says Ontario.

this # has been calling for 4-5 days now ...twice on the 8th .
I called it back and it says the # is not assigned. grrrr.
