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

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.

Just got a call from them and they tried selling me VIAGRA wow no need fpr that

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

(519) 570-4223 called 12:00 noon 08-30-11 came up as unknown name If you dont want to show me who you are...sqrew you! Called back...this # is not in service.

they are using skype - making it look  like a local number. they are calling from europe about some business thing - I had to pry that out as they wanted the manager and I said no - and they kept wanting to hang up and not say why they are calling.
