8. Interconnect two IP04
Purpose of this chapter: show how to link two IP04 in different location. With this function, we
can link branches together with IP04. Same method can be used when connect more than 2 IP04
in different branches.
8.1 Link two IP04 in the same network.
The simplest case to link two ip04 together is in the same network. We start from this and then
try to expand to different network.
Below is the structure of how to link two IP04s in the same LAN:
The idea of the how to connect two IP04 in different location is: 1) register the IP04A as an
extension in IP04B(via IAX2 trunk) so the extensions in IP04A can make calls to IP04B’s extensions
via this “special” trunk. 2) use the reverse method in IP04B to register to IP04A.
In above structure:
1) AT-530A registers to IP04A as an extension 6001.
2) AT-530B registers to IP04B as an extension 5001.
3) All the extensions under IP04A are in the format 6XXX.
4) All the extensions under IP04B are in the format 5XXX
5) Extensions under IP04A can make calls to extension under IP04B use format 5XXX.
6) Extensions under IP04B can make calls to extension under IP04A use format 6XXX.
7) The two IP04 links each other via IAX2 trunk.
Steps to achieve above objects:
8.1.1 Set up an extensions in IP04A for IP04B
In IP04A, go to User Page
Add New Exenions:
Extension: 6005 ; Phone number of this extension
Name: User_IP04B ; Caller ID Name
