I just got a cal from this # (519) 570-4223 I answered and nobody said nothing.
Have had them  before too.

Called me when i was sleeping off a night shift. Around 10 am that is. I guess i must have answered. But i dont think anyone was there. Got 3 calls in around 30 mins this was the last one. One was a blocked number and the other was another 570 number. I was worried i had hung up on a potential boss. But good to see it doesnt look like it.

I found out this is a fax number - it's from an online fax service - A friend of mine accidently sent it to me.

Keep getting calls from this number, same time each day. I can't understand who they are asking for and ask for a message and they hang up. When I try to call back the number is not in service. I get the same result when I do a reverse lookup.

This number calls our home repeatedly weekly and sometimes daily around 9:00 am and also in the middle of the night.  It is someone trying to fax us.  It's been going on for quite a number of years.
