It is the CLI for the outbound calls of the hotel on their PBX.

Yep, I picked up the phone, they asked for my husband, I said he wasn't home, they said they just talk to him, and to have him call the The Fairmont Royal York. (He was never talking to them) he's  tried calling back, as we stayed at the Royal York last month, thinking maybe something was wrong with the billing, but the phone just rings.So we did a search on the #. Found this site.Wonder what the point to this is? To see if were home? Why say the Royal York? Why did he not want to sell me whatever he's selling?It just really seems strange, very strange.

Who/which company is this? I am getting called at 12:30am and other odd hours in the morning?

Can u tell me what business is it

I get call from this number how can I know who call me?

Yes, it is the Royal York Hotel. It's possibly from the main truck. I received a call from a friend staying there, and this number displayed.
