Question Asterisk servers integration.

Dear community,

I have downloaded and installed the distro "Asterisk@Home". I didn't have any technical knowledge about traditional telephony, neither VoIP.
However, I've been reading a lot about Asterisk and I can configure a few SIPs, connect with a SIP client and call other SIPs from this list. That's fine, but now I need to estabilish a communication between two Asterisk servers, for example:

I have added the following SIP numbers to Astbox1:

While I have added the following SIP numbers to Astbox2:


If I'm connected to the Astbox1 as 2050, I can perfectly call to 2051, 2052, 2053. But never to 3050, 3051, etc.

What exactly I've to do to estabilish this kind of integration? Eg: 3050 calling to 2050, 2051 calling to 3053, etc.

I've read about SIP trunking, IAX2 trunking, etc... (I believe the solution is related to something like these)
but I sincerely don't got it. I have a good network knowledge, but, as I said, not a good telephony knowledge.

Could anyone help me, please?
Thanks in advance.

Thumbs up Connecting two asterisk boxes

You will need to set up a trunk.
The easiest is to install an IAX trunk between the two boxes
(It only requires one port to be open in the firewall)

Then you have to set up the routing so that when a certain extension range is dialed -- instead of going out to the Public phone network -- go to the trunk.

You have another option... You could link both offices vi a VPN and run all your phones off of the central server and use the second server as a backup in case the connection drops

Benefit are -- you could have roaming users that could log onto a phone in any office and their extension would follow them.

Also -- if you are running Asterisk@Home you may want to upgrade to AdminsParadise VoIP Phone and Fax...
Its free... it runs the latest version of asterisk (more features)
It supports roaming users out of the box.
It has scheduled conferences..
Web based faxing ....
