Real-time chat has boosted customer satisfaction and improves team efficiency and lead conversion

We could improve with better advanced chatbot customization, stronger AI-powered conversations, automatic deep CRM and third-party integration, more detailed analytics and reporting, additional customization options for chats, and improvements to mobile app performance and workflow automation. Regarding security, it is essential for customer-facing interactions. I would point out the real-time data lag, which is a significant gap, and enhancements in system reporting and live data update metrics are necessary. We also miss deep customer journey insights, along with user interface improvements, mobile widgets, and agent experience enhancements, especially with security and privacy configurations. On a scale of 1 to 10, I would rate 3CX Live Chat as an 8 because it has excellent control over the PBX license while enabling instant transitions from chat to voice and video calls. The reasons for losing those two points include basic analytics, widget customization options, and limited standalone chat tools compared to its competitors, which have higher market shares. With the right developers, they could excel in this area. The reason I chose the number eight is not only about analytics or customization but due to reliability bugs and agent workflow frictions, which affect the overall reporting coherence. Reliability and security glitches are significant drawbacks.

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

"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."

"3CX is a software-based PBX which can cover every company's needs."

"Since implementing 3CX Live Chat, we have seen our average response time decline by around 55%, customer satisfaction increase by approximately 45%, and lead conversations on the website chat improve by about 35%."

"The collaboration features allowed us to consistently provide cohesive communication with our customers as all team members could participate regardless of their geographic location."

"3CX technical support is top notch and the best of any vendor I've encountered so far."

"It’s straightforward to set up."

"3CX constantly adds new features based on their customers feedback and it is one of the most versatile PBX systems we have worked with."

"Mobility features and remote extensions work well."

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 actually has some stability problems. It actually lags and sometimes doesn't load."

"No issues with the solution, except its services require a business model change."

"Its features for scheduling and generating reports need improvement."

"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."

"The support team can appear to be condescending."

"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."

"Bring back the multi tenant ability in version 15 and above."

"The solution could improve the web meeting feature. There is a lot of competition from all the other applications that are out there, such as Microsoft Teams and Zoom. I find I do not use it that much. I do not know how much effort they are putting into the web meeting part of the program but it could improve."

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

"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."

"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."

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

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