Much has been made of the lack of multi-tenant functionality with Asterisk® and FreePBX®. Today we’ll show you how to interconnect as many Asterisk servers as you like and make transparent calls between all of them at zero cost. Setup time is under 5 minutes per server. When you couple PBXs with distributed infrastructure and inexpensive cloud servers costing $25 or less a year and on-premise virtual machine platforms including Proxmox, VMware ESXi, VirtualBox, Windows 11 WSL, and Mac UTM,… Read More ›

It’s been several years since we discussed interconnecting Asterisk® servers so today we want to do a version refresh using PJsip Trunking. We also want to show you how easy it is to secure the communications path by setting up the trunks using OpenVPN connections. When we’re finished, you’ll have a FREE way to call between sites using FreePBX® Outbound Routes. Because Incredible PBX comes preconfigured with all the components you’ll need, we’ll use that platform to further simplify the… Read More ›

Today we’re pleased to introduce an updated OpenSIPS installer for Debian 10 featuring the latest release of OpenSIPS. Our previous tutorial with Debian 8 is now obsolete, an all-too-frequent occurrence in the open source world. Today’s open source SIP server lets you connect users to make and receive free as well as commercial calls worldwide. There’s excellent documentation making it easy to integrate into our existing Incredible PBX platform without hiring a consultant. It’s also straight-forward to secure without providing… Read More ›

Since last Thursday when VoIP.ms suffered (and continues to suffer) one of the worst Distributed Denial of Service (DDOS) attacks in the VoIP era, we’ve been asked a thousand times whether any SIP trunking provider can provide a safe and reliable platform under circumstances similar to the VoIP.ms outage. We obviously cannot vouch for every trunking provider but, based upon our discussions with two of the major carriers that support Incredible PBX, we are confident that either of them could… Read More ›

We’re rounding out our softphone series today with the perfect complement to Clearly Anywhere for Asterisk® and FreePBX®. Let’s face it. SIP URI dialing from extensions is not Asterisk’s strong suit which is disappointing since SIP URI calling is free. If you’ve been following Incredible PBX® 2020 developments this year, you already know that we’ve pushed everyone to move their VoIP servers to the cloud. You not only get a more flexible PUBLIC platform that lets you go virtually anywhere… Read More ›

Perhaps the single most important component in the VoIP toolbox for any PBX deployment that includes traveling users is the softphone whether it’s deployed on notebook computers or smartphones. We’re kicking off football season with reviews of some of our favorite SIP softphones for mobile users. We’ve previously written about Linphone and Zoiper and Telephone. We’ve also sung the praises of earlier releases of Google’s Pixel smartphone which makes a perfect VoIP companion even without a cellphone provider. Today we’re… Read More ›

At every opportunity I always tell new VoIP enthusiasts that one of the true advantages of switching to a VoIP platform is the fact that you don’t have to put all your eggs in one basket. Just this morning, I read a Facebook post from one of the elders in my family lamenting the fact that her MaBell landline had failed in the midst of this week’s snowstorm in North Carolina. Her local WiFi and cable TV still worked but… Read More ›

Today we’ll introduce a number of new KVM cloud providers around the globe at rock-bottom prices plus some new additions to enhance our OpenSIPS firewall design. If you’re just getting started with OpenSIPS, check out the new KVM offerings below and then hop over… Read More ›
