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

"FreePBX offers the best features for a small call center for a small company with 20 or 30 agents."
"FreePBX positively impacts my organization because it would not be able to work properly without it, as a lot of server configurations are built on it and we fully rely on this system."
"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 has made a positive impact on my organization, and we have completed many projects with it."
"FreePBX has positively impacted my organization, and if I were to compare it to Elastix, I find it a lot easier to manage since it does not have a lot of bugs and is very user-friendly."
"I find FreePBX cost-effective as it does bring the return on investment and measurable benefits to my clients."
"It is the most user-friendly, flexible and resilient system for voice-over IP we have installed so far."
"My advice for others looking into using FreePBX is that it is reasonable and most of the features are free, so I recommend it."
"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

"AI is not 100% accurate and at the end of the day, a machine cannot be blamed for a mistake it has done; it is always the user's responsibility."
"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."
"However, when the call volume is large, sometimes FreePBX goes on halt, and because of that reason, I give it seven out of ten."
"One area where they can continue to focus their improvements is support for third-party phones on the endpoint manager module."
"Security would be the main feature that I wish was better because the FreePBX box can get hacked quickly."
"Sometimes when I receive reports that a user is not able to make a call out or they are having a call drop issue, viewing the dashboard provides no data."
"There are some limitation issues with concurrent calls; when we have concurrent calls, sometimes the entire PBX fails."
"I think FreePBX can be improved by offering users the ability to design a call flow more easily through a drag and drop interface."
"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."

Questions from the Community

What is your experience regarding pricing and costs for FreePBX?
My experience with pricing, setup cost, and licensing is that we only need to pay for the server through DigitalOcean billing. Since it is open source, you can have the ISO and install it on your own.
What needs improvement with FreePBX?
FreePBX has some monitoring and real-time monitoring features. They also have some SIP packet capturing. There is a third-party tool called Homer that is a great tool because it can capture call tr...
What is your primary use case for FreePBX?
I have implemented FreePBX in IVR features many times because I am a hardcore developer who first prefers customization. FreePBX provides many services, but sometimes we do not need all of them, so...
What needs improvement with Qrystal?
It might be helpful to have video tutorials embedded into the product that give you 15-30 second details about certain analytics, etc. Future version ideas? Would be nice to have a mobile app.

I use the product for monitoring telephony services.
