This number must be a switch board number, simply because I got a call from this number today and it is actually from Indeed.com. Every few weeks, one of Indeed account manager calls our company as a courtesy to check  if we need any help as we post a lot of jobs on Indeed. So judging by all the comments on this thread, I am assuming this number is probably an outgoing number from a switchboard.

This number is being used as a rental fraud at the moment.
They're pretending to be a missionary in nigeria and asking you to send the damage deposit and then they will have the keys to the appartment sent to you.

I work for a large hotel chain and we have received numerous calls from this number claiming to be our Tech Support. They then instruct us to go to a website which includes our company name in the web address, the screen then goes black and a porn video pops up. The person on the phone is always extremely rude and we have now been advised to ask for a case number when they call.

Got a call from this number but no1 answered when I said "hello"Called back and I got a busy signal.

Caller called and spoke in my mother tongue, Tamil and said that Telus has received complaints about our phone being used by Telemarketers. My husband asked what is your ID and call back number and he gave his Telus ID as 08 TEL 619 and gave 1 +1 866-585-1111 as a call back number. My husband said that he would call him back and hung up. I did google search on this number and got this thread.Previously there were calls from a Nebraska or Utah number who would just keep silent whenever we pick up. We stopped picking up calls from unknown numbers . But, this number caught us by surprise.
