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.

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.

This number is a calling # that will show up on your caller ID when people dail a certain number that gives you free long distance calls to anywhere in north america. I used to have the number and website but I can't remember it.  Anyways many companies including large ones like Rogers and Fido as well as bill or debt collectors all have started using this number to call clients or customers.  The (604) 855-7584 number is just the default routing phone # that is used to call customers in the lower mainland.  I will try to find the website again because it is handy to use to call anywhere for free.  Companies on the other hand should not be so cheap and they should not be allowed to use it because it covers their true identity.

My commodities broker calls me from Chicago and this number comes up. On another thread this number is identified as a major carrier trunk line. That is it is a major feed line for calls coming into Canada. It is probably used mainly by companies marketing some product or service but it also appears with cellular calls across the border. Roaming on cell, etc.

Or it could be boogie men, that sounds reasonable too!!!

I received a call from this number on my cell today saying they were calling to welcome me to Fido and that the needed to confirm some info with me.  I called Fido in the evening and this number is not on there list.  Fido tried calling and could not get threw.  The same number called me back in the evening and I argued with the lady on the phone cause she wanted to confirm the type of phone plan I had.  I told her to shove it.

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