RTPbleed Security Alert: Asterisk Calls Can Be Intercepted

RTPbleed Security Alert: Asterisk Calls Can Be Intercepted

Friday, September 8, 2017

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 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 ›

Finding the Perfect Phone Solution for Small Organizations

Finding the Perfect Phone Solution for Small Organizations

Many of us wear several hats during our business careers. One of those invariably is managing a community organization of some flavor. We frequently are asked for advice on what the ideal telephony solution would be for such an organization. The reason for the inquiries typically is because the Bell Sisters have now jacked up the cost of a single, business phone line to well over $100 a month. And that gets you local calls only unless you sign up… Read More ›

If you didn’t already know, we’ve always liked free. No strings, no gotchas, no demoware, and no legal shenanigans. That’s why our introduction of Issabel 4 last week was such a breath of fresh air. While there’s now an awesome free version of 3CX, the open source community has had a very long dry spell. So today we celebrate a decade of adding fun to phone systems with the introduction of Incredible PBX® for Issabel 4. It includes our next… Read More ›
