RTPbleed Security Alert: Asterisk Calls Can Be Intercepted

RTPbleed Security Alert: Asterisk Calls Can Be Intercepted

If you’ve installed Asterisk® during the past 4½ years, your server has a MAJOR security problem. If you didn’t already know, with Asterisk, your VoIP conversations actually are carried over a random UDP port using the Real Time Protocol (RTP), not the SIP port (UDP 5060) which handles the setup and teardown of your VoIP connections. It turns out that, since March 2013, all of that RTP traffic and thus your conversations could be intercepted and redirected by anyone on… Read More ›

A VPN for All Seasons: Introducing NeoRouter v2

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 ›

Twofer Tuesday: $1.50 Cloud Bargains for VoIP Deployments

Twofer Tuesday: $1.50 Cloud Bargains for VoIP Deployments

We’ve been big fans of $5/month VPS offerings of Digital Ocean and Vultr for many years. When Vultr reduced their lowest tier to $2.50/month, we were ecstatic. These weren’t ideal VoIP platforms because of their 512MB memory constraint, but they were perfectly suitable as a sandbox for experimentation. And then along came OVH with a 2GB VPS that was nearly perfect for VoIP at $3.49/month. As we all know, the Earth does not stand still, and WootHosting now has once… Read More ›

When it comes to choices in free PBXs, times have indeed changed. A decade ago your options went something like this. There was Asterisk@Home or Asterisk@Home. Then along came trixbox® and Elastix® and PBX in a Flash™ and AsteriskNOW®. What remained constant throughout this evolution was the underlying Asterisk® platform. With the exception of Digium’s offering, the remaining products all included the FreePBX® GUI. Then came a whole new way of looking at things with FreeSWITCH®. Another morphing occurred when… Read More ›

Keep On Trunkin’: Free International VoIP Calling Returns

Keep On Trunkin’: Free International VoIP Calling Returns

We’re kicking off a new series on VoIP trunks today. One of the main reasons is that Google has (again) warned that Google Talk (aka GChat), XMPP, and SMS messaging are going away on June 26. If true, that would mean that Google Voice (as we know it today) will no longer function on Asterisk®-based PBXs. If you’re smart and care about uninterrupted telephone and messaging services, you’ve got two months for contingency planning. Today we’ll be taking a fresh… Read More ›

Eight years ago, we introduced transcription for Asterisk® voicemail messages. When the messages were delivered by email, you got both a recording and the transcribed text courtesy of Google. As with most things Google, the licensing terms changed regularly and voicemail transcription became more convoluted until it became next to worthless. Today we begin our new exploration of IBM’s Watson Developer Cloud. It offers a rich collection of services at unbelievably low price points. We’re kicking things off by introducing… Read More ›

Once a year we like to step back and survey the latest and greatest VoIP developments for the coming year. And 2016 was certainly filled with surprises including the release of free versions of 3CX sporting the PIAF5 and Elastix 5.0 monikers. That, in turn, produced a wave of FUD from our friends at Sangoma® urging users to return to their open source roots. But guess what? Sangoma was pitching their FreePBX Distro®, another closed source product just like 3CX.… Read More ›

Embed from Getty Images 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. In light of last week’s major security lapse in the Asterisk® dialplan of those using FreePBX® since the Asterisk@Home days, now seemed like a good time for a review. As we’ve noted before, the problem with open source phone systems is they’re open source phone systems.… Read More ›
