We’ve previously documented the benefits of SIP URI calling. Because the calls are free from and to anywhere in the world, the use case is compelling. The drawbacks, particularly with Asterisk® servers, have primarily centered around the security implications of exposing SIP on a publicly-accessible server. Today we want to take another look at an open Internet SIP implementation for Asterisk based upon the pioneering work of Dr. Lin Song back in the PBX in a Flash heyday.

We covered Kamailio in our Part I article.

All you need is a desktop computer with wired or wireless Internet access or, on a smartphone or tablet, a cell data… Read More ›
