The server itself does load balancing however building a fail-over for it is difficult

The server itself does load balancing however the most difficult thing I found was building a fail-over for it. However, if you want to build a fail-over for it that's the tricky part since most sip traffic is routed using UDP. There are plenty of amazing TCP load balancers out there such as HAProxy but none for UDP. You need to use something like Keepalive and fail-over IP and restart the server on fail-over

Quotes from Members

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

Pros

"3CX Phone System is fantastic and easy to setup."

"The most valuable features of 3CX Live Chat are the integration with our existing CRM allowing us to get all of the numbers synced together, the communication aspect of the solution was always working very well, the sound quality was perfect, we were able to log into the application to check which users were using the solution and if they were in a call or not, and additionally, the solution integrates well with other CRMs."

"The management interface is hands-down the easiest I've ever had to use."

"I can safely say that there is nothing that beats the ease of deployment, functionality and stability of 3CX."

"The solution is basically an online phone, it doesn't charge you anything, you can contact people easier than using normal applications, and it has powerful and secure connections."

"The setup is wizard driven just like you would expect a Windows application to be, and it is super simple and straightforward."

"It is a highly flexible and easy to use platform which offers many benefits to our customers."

"The failover features that come on SP3 allow me to create a replica of 3CX PBX in case the 3CX fails, and the replica becomes active right away, minimizing downtime and data loss."

More 3CX Live Chat pros

"This product can scale insanely, the fact that it can handle hundreds of thousands of subscribers is great and means you won't have to worry about scalability for a very long time."

Cons

"It is not supported by Linux versions. This product is also not open source, which is not much appreciated by the guys like me, who love experimenting with the codes of any product they receive."

"They need to embed a help or chat feature."

"Some customers want to integrate a CRM solution with 3CX, but it's not compatible."

"Message management in 3CX Live Chat is a little tricky."

"3CX Live Chat could improve by being more customizable. There should be more skinning options for the appearance of the solution when we embed it onto a website. This would allow us to make it look more like part of our solution, rather than a third-party application."

"Message management in 3CX Live Chat is a little tricky. You can transfer a conversation to someone else if it comes into a group, but it isn't always easy to return the conversation to the group."

"3CX should combine the basic version and the enterprise version so that there is only one standard version instead of two."

"More granular management of call recording is needed."

More 3CX Live Chat cons

"Would be nice to have more sample config files for different kinds of scenarios rather then just one default config file."

Pricing and Cost Advice

"We used a yearly license depending on the customer's requirements, and the customers did not complain about the pricing."

"3CX sells an annual subscription, but we usually split it out monthly for clients, so they don't see an annual bill for the 3CX licensing, it's just part of their monthly phone bill. As they're paying us for carrier service anyway, we just roll it all together. Your standard phone service would be an additional cost, you either need to maintain a local carrier with POTS lines or PRI or a SIP, or you have to go with a cloud-based SIP."

"The price of the solution has been reasonable. We have not had any problems or complaints with the licensing model. We have not reached a point where we need to upgrade. We have all the correct channels."

"We have purchased an annual license to use 3CX Live Chat. There are different options available, you can pay monthly or yearly. I am completely satisfied with the pricing of 3CX Live Chat, it is cheaper than competitors and it is a better solution."

"The price of the solution is in the middle range compared to other solutions. There are different license options available. For example, there is a professional version and an enterprise version, and with the enterprise version, you have the ability to modify the dashboards. You can purchase a license at many different time frame increments, such as monthly, yearly, or two years."

"There is no add-on costing on the standard fees."

"There aren't any additional costs. With the license I purchased, I have all features that I need. I don't have to buy an add-on or another license."

"Switching from POTS or PRI to SIP Trunk save the customer real costs. ROI is seen in less than a year."
