Shared user list btw 2servers

Hello there!

Your help is required to me, somebody can explain in detail to me as to solve a following problem>>

I have 2 servers, a server 1 is in office 1 - a server 2 at office 2.

Users which are connected and use for dialogue a server 1 wish to see in the contact-list the full list of users from a server number 2.

Is it possible to decide this problem or not?

I apologize for my bad English.

Vlad.
