How it works and who provides a room 8-800?

the company has the type number 8-800, how it works and who it provides, no one knows.
1) Want to understand how to work the room: It is a separate room which can be connected via SIP to IP PBX or is a number that is somewhere from the operator, and it contains an unconditional call forwarding to the numbers of the organization?
2) How to find out who provides this number?

1) Can be either way
2) Take out the extract from the register of the Russian system and numbering plan "Codes ABC-8x" in a convenient format to search for what range gets your number
