This is like Vancouver's default number when they can't figure out the caller ID. It sometimes also appears to be when I receive international calls.

(604) 855-7584  was screening my calls and this number appeared.  checked on here and see it's not anyone i know!  is it a scammer???

It is some kind of phone exchange, i just got it today and a message from a collection agency that they had changed their name...it was legit for me.

I got a call from this number, and when I answered no one was there.  I answered, HELLO three times, and nothing.  About a minute later though, I got a message on SKYPE that my daughter had tried to call from Germany and I had answered and said HELLO three times but couldn't hear her.I called her back on SKYPE and sure enough it was her that had called.  I assume that the number (604) 855-7584 is a number that routes SKYPE calls.  This could be why you get the long busy signal when you try to call it back, and that no one can trace the number to anyone.  This means that you are either getting a legitimate call from someone you know from SKYPE and it just doesn't connect through to you. It is also true then that if the call connects and someone speaks to you and tries to scam you, that they are using SKYPE to make these types of calls.Hope this explanation helps someone figure out who may be calling.

just got  a fraud cheque from the guy and its apparently pretty  popular frauding agency. cops cant do anything  cause of the dial tone. its people going to offer  work from home or something like that dont do anything cause i almost got caught selling tires to them. just thought i would warn  whoever get s calls from these guys.    all i  know is that the names james robertson is one fake name and so is something bernard. so be careful
