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.

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

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.

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.

Just got a call from this number.

Computer voice said i need to extend my warranty on my car. funny thing is my extended warranty is almost up so i pressed one. then a live guy came up to confirm my car and then i asked him what car they were talking about.

I told him IDK you tell me, your the guy that told me my warranty is up. then he hung up on me.
