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 has strong reporting and management features. You can manage the capabilities of a call center with queues and timers. It's a complete solution."

"The monthly savings on service alone pays for the system in 8 months or less."

"Because it’s quite easy to deploy and operate, it has allowed us better disaster recovery options for our clients."

"I’m not saying it’s the best system in the world, but at the price point, it is exceptional value when looking at the features you receive with the Pro licence."

"The integration with SMS has been helpful. That's how a lot of customers prefer to communicate nowadays. It makes it convenient for the customer to reach us."

"I have been using it in my environment, and if you use it, you have to say that VoIP can't get any simpler than this."

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

"It lets you see how many calls you made, the time you called, and how many minutes you spent on the phone."

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

"I need a robust provider who can help me use Live Chat. Unfortunately, I have to move from one provider to another because they don't have enough capabilities to maintain good service."

"There are a lot of quality of life things that could be improved. When adding extensions, you need to use the extension import setting, you can't just use an import function to update extensions. You have to delete and recreate the extension, which can have all kinds of unintended consequences."

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

"iPhone users found it difficult to use the mobile application when working offsite."

"It could be better in terms of providing more options for call recording."

"I would like to see is for the status to have a “time in status” field so people can see how long someone has been in that particular status."

"It needs a better training and certification process."

"For firewall: Its advice is to disable the firewall to allow voice to pass through the network, but there are instants when you don't disable the firewall for security reasons that NAC port comes in."

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

"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."

"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."

"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."

"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."

"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 is reasonable. There are a few license options and we are using an enterprise license."

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

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