As part of our ongoing development efforts, we maintain about a dozen honeypot servers across the U.S. and Canada to monitor the latest adventures of the bad guys. Security becomes especially important for those wishing to live on the bleeding edge and deploy a cloud-based, public-facing VoIP server. Today we want to walk you through our latest suggestions to set up and secure a VitalPBX platform using just the built-in FirewallD, IPset, and Fail2Ban components. If you opt to deploy… Read More ›

Last week we introduced a new methodology for deploying Incredible PBX® and Asterisk® on the wide open Internet. And this week we’ve put all the pieces together in a One-Minute Installer that will transform any Incredible PBX 13-13.10 server into a public-facing server platform in under a minute. Today you not only get the cupcake, but also some of the sprinkles in the form of tips or scripts to whitelist providers and users, to adjust countries on the blacklists, to… 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. 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’ve embellished… Read More ›

Last week we introduced OpenSIPS, the multi-functional, multi-purpose signaling SIP server which can fulfill almost any communications function one can dream up except the unified communications tasks typically performed with a PBX such as Asterisk®. Today we want to marry the two platforms to give you the best of both worlds. For Incredible PBX® users, the primary advantage of adding an OpenSIPS front end is the elimination of the complexities associated with interacting with your PBX from remote sites with… 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 ›
