We get calls from this number sometimes as frequently as 5 times a week.  Most of the time there is no answer.  A few times we have spoken to someone who says they are from the cancer society or the firemen's association selling tickets for a magic show.  When we get a person we asked to be taken off their call list.  We've decided to answer and then hang up as soon as it connects.  Feels rude but this is a real nuisance we are trying to discourage.

My daughter also got this number calling her cell. She said she answered it and it was Primus.

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!

This is a num. used for clubed calles by a compani in abb. bc. i am geting calles every day form this number sevral times a day no one ans. and u can't track this number as this is a call made by computer

Someone phoned looking for my wife but wouldn't leave a message and said he would leave her a message on her cel. she did get a message on her cel right after but the number showed up as something different but ehen I described his voice it seems like the same guy. I agree with the person who thinks it's a default for a blocked number...

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.
