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

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 ›

The world of cloud-based computing has profoundly changed over the past year. And today we want to take a fresh look at the cloud landscape for those of you that spend considerable time experimenting or tweaking software applications either for customers or for your own organization. First, a brief paragraph of history. We began our cloud experiments almost seven years ago when Amazon S3 was still in its infancy. At the time, Amazon S3 was a real bargain even with… Read More ›

Some of us have spent years developing secure VoIP solutions for Asterisk® that protect your phone bill while bringing Cloud-based solutions within reach of virtually anyone. So it’s particularly disappointing when a hardware manufacturer spreads fear, uncertainty, and doubt in order to peddle their hardware. In this case, it happens to be Session Border Controllers (SBCs). We want you to watch this latest “infomercial” for yourself: https://youtu.be/Bp_7m64k_ko To hear Sangoma tell it, every VoIP server protected by merely a firewall… Read More ›

View image | gettyimages.com We continue the Incredible PBX for Asterisk-GUI adventure today with a close look at SIP URIs, those email-like addresses that are the fundamental building blocks for VoIP technology. Consider this. If everyone in the world had a SIP address instead of a phone number, every call to every person in the world via the Internet would be free. That pretty much sums up why SIP URIs are important. The syntax for SIP URIs depends a bit… Read More ›

One of the exciting challenges of building a swimming pool is knowing that it’s just a matter of time until your Internet connection dies. As you might imagine, swimming pools are major construction and involve a lot of digging. And digging usually means some oops moments when cables get cut. In our case, we had watched the folks digging the trenches for all of the pool plumbing to be sure they didn’t accidentally whack one of three coax cables coming… Read More ›
