Today we want to show you how to reconfigure Incredible PBX 2022 for Rocky 8 into a PUBLIC-facing Cloud PBX.

A PUBLIC-facing PBX also provides free SIP URI connectivity to users of your PBX by anyone from anywhere in the world.… Read More ›

Seven years ago we introduced Travelin’ Man 3 to simplify the task of securing the Incredible PBX® VoIP platforms. Today we want to reexamine the Travelin’ Man 3 firewall design for the benefit of those that are new to Asterisk® and FreePBX®. In the old days, FreePBX-based VoIP servers were notoriously vulnerable because of numerous bugs in the original FreePBX code which was developed by dozens of developers around the world with very different skill sets. Not only did you… Read More ›

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.

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’ve embellished… Read More ›

Since giving up on Google Voice, we’ve been extolling the virtues of SIP URI dialing which gives you unlimited free calls to anyone else in the world that happens to have their own SIP URI address. SIP URIs look very much like email addresses except they’re used to share phone conversations instead of email messages. And, as we’ve mentioned previously, if everyone in the world had their own SIP URI, paying for phone calls would become a thing of the… Read More ›
