Interconnecting Asterisk Servers with PJsip and OpenVPN

Interconnecting Asterisk Servers with PJsip and OpenVPN

It’s been several years since we discussed interconnecting Asterisk® servers so today we want to do a version refresh using PJsip Trunking. We also want to show you how easy it is to secure the communications path by setting up the trunks using OpenVPN connections. When we’re finished, you’ll have a FREE way to call between sites using FreePBX® Outbound Routes. Because Incredible PBX comes preconfigured with all the components you’ll need, we’ll use that platform to further simplify the… Read More ›

Introducing OpenVPN for Incredible PBX

Introducing OpenVPN for Incredible PBX

We’ve been wrestling with virtual private networks for more than 22 years now. 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. Over a decade… Read More ›

Interconnecting a Mobile PBX to the Asterisk Mothership

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.

A VPN for All Seasons: Introducing NeoRouter v2

Today, we want to revisit our favorite client-server VPN, NeoRouter. It’s included with all versions of Incredible PBX® and eases the pain of setting up air-tight firewalls as well as High Availability (HA) redundant servers with VoIP. NeoRouter relies upon a central server and uses a star topology to connect remote nodes. The major difference between NeoRouter and PPTP VPNs is that only registered devices participate in the virtual private network so there is no direct access to other machines… Read More ›

With the advent of cloud-based computing and desktop virtual machine platforms like VirtualBox, we haven’t played with dedicated hardware for Asterisk® in a couple of years. WOW! It’s just amazing the quantum leaps in miniaturization, price, and performance that have transpired during our absence. Last week, we introduced a dedicated server platform for under $200 that could serve as a small business PBX for almost any 20-30 person organization. Today, meet Big Brother. You’re looking at all the components that… Read More ›

Firewalls 101: Why Every Asterisk Server Should Have a Functioning Firewall

Firewalls 101: Why Every Asterisk Server Should Have a Functioning Firewall

Monday, August 3, 2015

View image | gettyimages.com Part of our fundamental disagreement with the FreePBX® design can be summed up in one word: FIREWALL or the lack of a functioning firewall in the FreePBX Distro and in the functionally identical Digium product, AsteriskNOW®.1 Most of the other design choices including the controversial, non-GPL compliant Module Signature Checking mechanism are touted as failsafe ways to detect altered systems even though changes in FreePBX MySQL tables and Asterisk config files can be modified easily without… Read More ›
