If you were expecting to read about ShoreTel, Cisco, or Avaya, you’d be wrong. While these are “VoIP” systems, I’d like to draw some attention to the new world order of IP telephony. It’s no secret that the big names in VoIP (mentioned above) are suffering, and it’s all thanks for a little piece of software called Asterisk. Not to discount the contributions of Freeswitch, but Asterisk is, go here for a little background.
Many have harnessed Asterisk to create some pretty great turn key solutions. Below are my top 3 recommended Asterisk systems from years of deployments and obsessive tinkering. Behold, my shortlist.
Honorable Mentions: Keep an eye on these.
Ombutel is a derivative of Xorcom’s iteration of an Asterisk based platform, and it’s great. The user interface is clean, makes sense, and it supports FOP2 (flash operator panel). As with FreePBX, Ombutel is 100% free and virtualizes nicely. It is however still a little lacking in features when you compare it to FreePBX, and out of the box support for certificates is non-existent. I would like to see a self-signed certificate out of the gate at the least. Because of this, installations should be limited to on-prem. However, they are constantly adding features and fixing bugs. A major differentiator for Ombutel is their Class of Service (CoS) feature. This allows administrators to finely restrict or allow access to parts of the phone system from internal extensions. Normally, this is a features you’d have to pay for with other systems. Ombutel has a very active online community and are constantly receiving and replying to feedback. If Xorcom keeps this product alive, I expect it to do well.
Wazo, formally Xivo, is another 100% completely free system that is also feature-rich, but has a rare High Availability feature right from the get-go. High Availability is typically an expensive add-on, and that makes Wazo a really interesting product. Wazo is the most rough around the edges system in this list, but it has a lot of potential. Before it was Wazo, I found Xivo easy to install, but since they’ve gone through some changes, I haven’t been able to get Wazo to behave correctly when virtualized. I found it to be very buggy and dysfunctional. With that said, I am looking forward to the future development of Wazo. It’s very much a PBX un-plugged. If it were a car, it would be a driver’s car.
