If someone from British Columbia calls you from Skype it will show up as this number sometimes.

i posted an add on criags list ...thats when i started getting these calls

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.

I get a call from this number everyday. ?person on the end says they are calling form rogers and its a customer service courtesy call.  I asked them to remove my number from the calling list as I don't want to receive theese calls.  the paerson twice said they will do and won't call again but I'm still receiving these calls.  I think its fraudulant.

(604) 855-7584 calls me many many times a day!

calls everyday. left a message one time, saying they are from some country in africa, and they want to send me some money.. scams! they even send me text messages wanted to be my friend.. soo annoying! i've seen these type of scams from dateline!
