The following case shows the way to inter-connect two Asterisk servers such that users in different location can not only call internal extension numbers but also other person's extension numbers in other location directly.

Server 1:

Location: TW
Hostanme: tw.asterisk.org
Network segment: 192.168.1.0
Extension 2001: John
Extension 2002: Susan

Server 2:

Location: SZ
Hostname: sz.asterisk.org
Network segment: 192.168.2.0
Extension 3001: Peter
Extension 3002: Mary

Server 1: TW Settings:
