Migration projects have cut licensing costs and now support flexible call flows and hot standby
FreePBX can be improved as they come out with a new version every year or so. Their current version is FreePBX 17. The user community and the FAQ are great; you can search for just about anything you want to do on FreePBX and they're getting new AI engines and new text to speech engines from third party vendors all the time. So it's a very rich community. Sometimes the security is a bit odd with FreePBX, but security is a bit odd overall, so I don't know if that's a valid concern. I appreciate it; it's a good environment. Sangoma is the owner of the system. If I ever get stuck on something, and it doesn't happen very often, I can call and get help from Sangoma, and sometimes they want me to pay for it. It's fine if that's what it takes, but there's great support.

Real-time insight into voice quality issues has improved customer experience
I use Qrystal for real-time IMS troubleshooting and statistics for VoLTE/VoNR The partner is very sensitive to customer satisfaction and keeps seeking ways to identify any service degradation as quickly as possible. With Qrystal, we can spot any issue with customer voice quality down to its root…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is the most user-friendly, flexible and resilient system for voice-over IP we have installed so far."
"Since it is a free solution, all the features FreePBX offers are valuable."
"The call routing features with FreePBX have enhanced our customer service, with several sites all connected to a single central deployment, allowing people to work remotely from different locations using the same system."
"FreePBX has made a positive impact on my organization, and we have completed many projects with it."
"I have seen a return on investment with FreePBX; for example, the musical instruments group saved over $30,000 a year by moving from Cisco to FreePBX for their licensing."
"FreePBX offers the best features for a small call center for a small company with 20 or 30 agents."
"Qrystal stood out during our assessment for voice quality monitoring and proved its value in the first month after deployment."
"The product and team have helped us maintain best-in-class telephony service for our users."
"Qrystal stood out during our assessment for voice quality monitoring and proved its value in the first month after deployment."
 

Cons

"Sometimes the security is a bit odd with FreePBX, but security is a bit odd overall, so I don't know if that's a valid concern."
"One area where they can continue to focus their improvements is support for third-party phones on the endpoint manager module."
"I think FreePBX can be improved by offering users the ability to design a call flow more easily through a drag and drop interface."
"Security would be the main feature that I wish was better because the FreePBX box can get hacked quickly."
"I believe FreePBX could be improved regarding the user interface. Sometimes the user interface has bugs, and when you apply configuration changes, they do not always apply properly."
"Qrystal could be improved by including Diameter KPIs."
"It might be helpful to have video tutorials embedded into the product that give you 15-30 second details about certain analytics, etc."
