About once a year, we try to shine the spotlight on Asterisk® security in hopes of saving lots of organizations and individuals a little bit (or a lot) of money. The problem with open source phone systems is they’re open source phone systems. So the bad guys can figure out how they work just like the good guys. That’s not to suggest that proprietary phone systems are any more secure. They’re not. It just may take the bad guys a… Read More ›

If you’re like us, spending $50 a month or more on a home security system is a bit like pouring money down the toilet. Add to that the complications of getting one to work reliably with VoIP without spending another $50 a month on a Ma Bell vintage telephone line just adds insult to injury. So perhaps you can share our elation when an email arrived last week announcing Straight Talk’s new Remote Alert System, a $10/month cellular-based system that… Read More ›

We’ve devoted a lot of energy to Asterisk security over the years with our Primer on Avoiding the $100,000 Phone Bill and our 20 Failsafe Tips and our SIP Navigation Guide plus numerous tutorials on deployment of Virtual Private Networks to secure your servers and phones including NeoRouter, PPTP, and Easy OpenVPN among others. But, when it comes to ease of installation and use with rock-solid security, nothing comes close to deployment of WhiteLists with the IPtables Linux firewall that’s… Read More ›

UPDATE: Here’s a newer Asterisk appliance for under $30. Grandstream has done with Asterisk what Samsung and others did with Android. You basically take a freely available, open source toolkit and transform it into a terrific piece of turnkey hardware with tremendous savings in development costs. While it’s great for consumers, to us it highlights what is wrong with the GPL2 license which lets companies do this in the first place. These for-profit companies give almost nothing back to the… Read More ›

That’s the Amazon pitch for their service. Ours is a bit different. For anyone with mission-critical operations or that has ever given a moment’s… Read More ›

We often tell the tale of the early Asterisk@Home days when almost every server was configured with no firewall, unlimited web access, and a 201 extension with a password of either 201 or 1234. What could possibly go wrong? Remember this Monday morning newspaper headline? “Small business gets $120,000 phone bill after hackers attack VoIP phone.” News.com.au ran this story back in 2009: “Criminals hacked into an Internet phone system and used it to make 11,000 international calls in just… Read More ›
