519-763-5000

The number is registered with Distributel - a long distance call company.

Someone called me on my mobile phone at 8:24 am on August 5, 2008 i attempted to call the number back and when i called this number
1-519-763-5000 it went to a dial tone  i would like to know how this person got my mobile number. send me an email to michael.madden@sheridanc.on.ca

I just got a call from that number, I didn't pick up, but a message was left and it was a friend of mine.  I think he was using a free long distance company that uses that number for the Guelph area.

519-763-5000 is the local access number in Guelph for Distributel.  If a person uses Distributel as their LD provider, they dial this number to access the system and call other people.  On the receiving end of things, you will see this number whenever anyone using Distributel calls you using the Distributel LD service if you are in the Guelph area.  In Toronto, you would see 416-969-5000, in Ottawa 613-237-7000, and so on.  

As for the dial-tone on call-back, that's how their system works.  When a subscriber dials the local access number it rings through to the system and gives them a 2nd dial-tone at which time they enter the desired LD number.

I don't need a call from this number
