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 ›

We covered Kamailio in our Part I article. And we’ve skipped writing about SIP server contestants two, three, and four because they each had a healthy dose of insurmountable problems… at least for us. So today we’re pleased to present Part V in our SIP server series. And, as the headline exclaims, with OpenSIPS we’ve found a platform that finally is worthy of your attention. Our requirements were fairly straightforward. We wanted an open source SIP server to which we… Read More ›

The Holy Grail for a mobile VoIP solution is a simple way to connect back to your primary Asterisk® PBX via Wi-Fi from anywhere in the world to make and receive calls as if you never left. Let’s tick off the potential problems. First, many home-based PBXs are sitting behind NAT-based routers. Second, almost all remote Wi-Fi connections are made through a NAT-based router. Third, chances are the remote hosting platform blocks outgoing email from downstream servers such as a… Read More ›

This month marks our twentieth anniversary wrestling with virtual private networks. Here’s a quick walk down memory lane. Our adventure began with the Altiga 3000 series VPN concentrators which we introduced in the federal courts in 1999. It was a near perfect plug-and-play hardware solution for secure communications between remote sites using less than secure Windows PCs. Cisco quickly saw the potential, gobbled up the company, and promptly doubled the price of the rebranded concentrators. About 10 years ago, we… Read More ›

Over the past decade, there is no subject that we have devoted more resources to than searching for the best platform on which to run a VoIP server.

Today we’d like to share what we’ve learned. Incredible PBX is a complex application. With close to a thousand moving… Read More ›

Let’s chat about Google. We’ve had a love-hate relationship with Google for the past decade. For every good deed they do, they always manage to follow it up with a swift kick in the teeth… or lower. Business Insider recently catalogued all of the Google carnage over the years. And that ignores the train wreck that many VoIP users experienced with Google Voice. So we have mixed emotions about writing this column at all. But, suffice it to say, you… Read More ›
