I’ve been working tonight to extend my world domination … er, I mean, to set up my Asterisk PBX. The next piece of the puzzle is how to move SIP calls across a NAT firewall. That way I can make use of Free World Dialup, Packet 8, and other services.
The magic to make that happen is called a SIP Proxy. The good news is that there are plenty of open-source proxies to choose from. The bad news is they all depend on the GNU oSIP libraries. Since the GNU servers were compromised recently, I cannot find recent versions of this fast-evolving library (i.e., libosip2).
That means I’m limited to making calls inside my home network for the time being. Which kinda gets old after a while (ask Kelly).
Could I get a little three way calling with that?
