I have been receiving calls from this  # several times over a period of days @ differing time  ..comes up private #  tried calling  back  and receive a strange tone sound.

I gave them phone call and they called like 20 mins ago. so i phpned them and i got a tone like beeuhhhhhhhhhhhhhhhhhh after like 4 seconds later they machine said please try dial the number again ?

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.

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

this number continues to phone my house and my cell all the timeI phoned my telphone company and all the can tell me that ita telemarketer and when you call back it rings busy
