We’ve got some revolutionary VoIP projects coming your way over the next several weeks, but I’m sorry to say the hardest part of them is getting your server configured to use secure and encrypted web communications via HTTPS. This is quickly becoming a universal requirement of most of the major technology players. So what might not be the most glamorous VoIP topic for a Monday morning is not only necessary but long overdue. The good news is that obtaining, installing,… Read More ›

With the Digium announcement last week that four and a half year’s worth of Asterisk® servers were vulnerable to the RTP eavesdropping bug, it prompted us to dust off our Incredible PBX® 13 for CentOS build and bring it up to current specs including the Digium patch for RTPbleed. And then along came Hurricane Issabel to remind us that sh*t happens, and it pays to have a backup plan for your telecommunications infrastructure. So today we’re pleased to introduce two… Read More ›

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 ›

Another Perfect Pair: Flawless VoIP with Wazo and 3CX

Another Perfect Pair: Flawless VoIP with Wazo and 3CX

We previously documented how to interconnect an Issabel PBX with 3CX to take advantage of the best of both worlds. Today, we’ll again use the Nerd Vittles free 3CX server offering and interconnect it with a Wazo PBX. An added benefit of using Wazo is the fact that you can set up redundant (and free) HA servers with Wazo in minutes. Once we get the pieces in place, from Wazo extensions, you’ll be able to call your 3CX Clients by… Read More ›

Today we’ll add another free worldwide calling option using iNum™. As with SIP URIs, iNum provides a way for anyone in the world to reach you by phone without paying a nickel. And iNum adds the same functionality for Issabel PBX users to reach anyone else in the world with an iNum phone number. The iNum project… Read More ›

SIP URIs make the VoIP World go ’round. They’re the email-like addresses that carry VoIP calls between SIP servers to reach their destination. But there’s gold in them hills if you know how to use SIP URIs because SIP URI calls are free even if the calls travel all the way around the world. We previously documented how to deploy SIP URI calling with PIAF5 and 3CX, and today we’ll show you how to make SIP URI calls from and… 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

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 ›
