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 ›

Earlier this year we demonstrated how to set up a publicly-accessible Asterisk® server to enable free worldwide calling using SIP URIs which are email-like addresses for VoIP and video calls. But not everyone has an Asterisk server so today’s tutorial extends free calling to everyone with a Windows or Linux PC, a Mac, or any smartphone or tablet. All you need is a desktop computer with wired or wireless Internet access or, on a smartphone or tablet, a cell data… Read More ›

Full Disclosure: We’re not exactly big fans of Sangoma® and their stewardship of the Asterisk® and FreePBX® projects. So read our commentary with a grain of salt or two. As we predicted when Sangoma purchased Digium®, the employee exodus has begun. The biggest surprise is that a disturbing number of the departures are from the FreePBX SchmoozeCom operation including two of its founding partners: Tony Lewis, the soon-to-be former Chief Operating Officer (COO) of Sangoma, and Brian Walters who has… 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. While our experience primarily has focused on finding the perfect fit for Incredible PBX®, much of what follows applies equally to any other Linux-based VoIP server including Wazo, Issabel, VitalPBX, and 3CX. Today we’d like to share what we’ve learned. Incredible PBX is a complex application. With close to a thousand moving… Read More ›
