What is 3CX? Key features and things to consider.

When you hear the name 3CX, people picture a giant capable of handling everything. That’s true; this software has all the features of a modern call center on computers and mobile devices. But what is 3CX, and can it really help your company?

What is 3CX?

Unified communications (UNC) is becoming the new standard in customer communication and service. Communication channels must be unified and synchronized. 3CX provides multiple services simultaneously, such as voice calls, conference calls, messaging, email, and fax. Users can log in and use the call center service via computer or mobile device, as the software fully supports Windows, Mac OS, iOS, and Android.

The 3CX communication system has won numerous awards from major global corporations such as McDonald’s, Pepsi, and American Express.

Benefits of 3CX software for your business:

Customer service anytime, anywhere with a telephone system is your need. A modern call center should leverage 3CX’s mobile features to improve employee productivity and customer service.

“All in one” is the word to describe this PBX system. You might not believe me, so let’s look at the benefits 3CX offers:

Minimizing Costs

Unlike traditional telephone systems, the 3CX system is entirely software-based, so there’s no need to invest in expensive physical hardware. This solution focuses on call-based licensing rather than the number of extensions you want to add to the PBX. What does that mean for you? 80% reduction in your phone bill while still ensuring company growth. Additionally, with the SIP protocol, all internal calls are free. SIP trunking allows you to swap outgoing calls with customers on the same network, minimizing call costs.

Easy to Install and Manage

3CX can be installed on any device you need, allowing you to communicate seamlessly in the office or on the go. This software is fully integrated with Android and iOS and can be used directly from your desktop computer. The system allows you to store all your business communication data on a virtual server using cloud computing technology, meaning you can easily access information from your desk or from anywhere.

Basic 3CX installation process:

Use pre-configured templates for easy integration with SIP Trunk providers. You can also request customized configurations to suit your company.

Automatic configuration with Plug & Play IP Phone interoperability.

Install PBX security features and automatic updates.

Deploy in the cloud or on-premises on Windows, Linux, Mini PC.

Through a modern, intuitive management dashboard, you can:

And that’s it! You’ve set up your own Cloud PBX.

Unified communications with 3CX

3CX is truly a unified communications solution, meaning it goes beyond basic call and call handling. This PBX can integrate many advanced features such as CRM management, messaging, calls, live chat, web conferencing, iOS and Android apps, email, and more.

CRM Integration

CRM, or customer relationship management, is a system for managing a company’s relationships and interactions with customers or potential customers. This is crucial for most businesses as it centralizes all information about their customers. Businesses can easily control important data such as contact information, company details, purchased products, interactions, etc.

3CX allows you to easily integrate your PBX and CRM system. The system can log calls and track customer interactions and profiles from any channel. CRMs such as HubSpot, Microsoft Dynamics, Salesforce, and other database software like Zendesk can all be integrated with the 3CX PBX. Administrators can integrate the CRM without plugins or manual configuration.

Live Chat

Live chat allows businesses to interact with their website visitors in real time. Website visitors can chat with the sales team and receive support in the browser’s chat box. Companies with good live chat support can increase customer satisfaction, thereby boosting sales. According to Zendesk, live chat has a 92% customer satisfaction rate.

The Difference Between 3CX and Other Call Centers

How to Register and Call Streaming

The main difference between 3CX and its competitors is the service registration license. Unlike call center services that charge based on the number of users, this solution charges a service package price based on the maximum number of calls. This means that regardless of your company’s size or number of employees, the price will be fixed. This solution is particularly useful for companies with a large number of employees but low call volume.

Another difference between 3CX and other call center systems is the features they offer. Most PBX and VoIP services have call routing functionalities that can be customized for each specific implementation. However, you have to contact the service provider to do that. 3CX has additional features that allow for complete customization of your call flow.

The CFD call flow designer lets you handle incoming calls and create complex call flows without programming or scripting. This means you can route calls during the day, direct calls based on customer input, implement voice payment gateways, and more. You can make your call flow as simple or as complex as possible.

3CX PBX Hosting

3CX offers businesses a great choice of on-premises or cloud hosting. For those who want higher security, you can even have both, providing a near-perfect redundancy solution. Although the PBX system is designed as a cloud-hosted system, the PBX software can also be deployed on a regular desktop PC or even a Raspberry Pi.

Today, many companies outsource their 3CX phone systems to third-party PBX providers for system management. This is a hosted service that is quick and easy to set up and eliminates expensive installation costs. System responsibility and administration are transferred to the provider. This solution is quite similar to leasing a smart PBX system, which many businesses are already using.

Which businesses are suitable for 3CX?

Generally, it can be deployed to businesses of all sizes. The quick setup and competitive pricing are advantages of this solution. The key consideration is your company’s call volume. If you have high call volume needs, you should also consider other PBX solutions. 3CX, along with cloud-based call centers, currently dominates the field of communication and customer service. Consider carefully to make the best choice for your business.
