Who called from 2503723083

This phone number keeps showing up on our home phone at different hrs of the day.

Fax machine sounds when I pick up the phone. Calling all hours of the day.

I have a fax machine calling me at all hours from this number. My Number is 250-573-5965. I would like these calls to stop.

I have had this number show up on my call display when various people call.  I have had calls direct from a distrubiter in China, Collection Companies looking for someone that does not live here, and my roommate has called me  from his Bell mobility cell phone and my call display has showed this number instead of his.  
I have heard someone mention something about the numbr is a general router number.  I'm still trying to figure out what that means.

This phone number appeared on my cell as an incoming call.  I tried several times to dial the number back and always just got a dial tone.
