Hi, I am newbie at FreePBX and Asterisk. I am just messing around with it to learn more about SIP servers and B2BUA Servers.
I have setup a FreePBX server on my Raspberry Pi at home. It is connected to a router with a public dynamic IP address and port forwarded the relevant ports, so I can take calls to any user connected at that time from anywhere. And I setup another FreePBX server on a Raspberry Pi at one of my friends. But this server doesn't have a Public IP address. It just functions as a SIP server within his home.
What I want to know is, if it is possible to establish a IAX2 link or some other form of link to connect my server and to my friend's server which doesn't have a public IP address? Is there some other way to connect my friend's server to my server as an extension?
I am very new to this and still learning. I just want to know if it is possible to this. And if so, how to do it.
Thanks!!!
