3CX describes its service as a reinvented PBX or private branch exchange. It’s available as an on-premise or cloud-based system, and you can choose to host or have 3CX do it for you. This feature ties in with the company’s aim to make the system hassle-free with minimal management time required.

One way 3CX aims to stand out among the best unified communications software providers is to make its services available in-browser, which means apps and accounts aren’t required for videoconferencing. All of the editions offer unlimited users, and it can be accessed on mobile devices and web browsers.

When it comes to risk management, an effective communication system and 24/7 support from the provider are vital. Those are two strong points for Crises Control, which offers a demo and free trial of this software.

What Customers Are Saying

Customer reviews of this software are enthusiastic about the functionality.

What Is Unified Communications Software?

Unified communications software refers to platforms that provide phone or messaging systems and collaboration tools. They’re specifically designed for improving connections between staff, whether they’re one site, working remotely, or based in several locations across the globe. It means that no matter where you work, you can still answer calls, share documents with your team, and support your customers.

Many of these systems are cloud-based to support remote workers. However, you’ll also find hybrid approaches with on-premise hosting. Some provide hardware and softphone access, whereas others use browsers and applications on existing devices.

The types of communication can vary by platform, but most include core features like messaging, file sharing, voice and video calling, team collaboration, and conferencing. Others build on these features and act as a full customer service interface, adding contact center call management and live chat for websites.

Typically companies are getting more than just a phone line, although the platform will center on PBX or VoIP capabilities. You’re able to access these from different locations on your phone, through a browser, on an office phone, or through a specific application.

Benefits of Unified Communications Software

No matter if you’re a small, medium or large business, unified communications software has several advantages that will assist you:

  • Reduced costs: Not only does UC allow you to consolidate your systems, which is the first step to reducing costs, it also cuts expenditure elsewhere. That could be through travel expenses due to videoconferencing or a reduction in hardware costs as existing devices can be used.
  • Enhanced productivity: Results speak volumes, and unified communications can improve yours by giving your employees options for how they prefer to work. It could be working from home, using team chat, or screen sharing at conferences, but it all helps to create the right environment.
  • Improved user experience: As well as using your UC strategy to boost staff morale and productivity, it can also benefit your relationship with your end users. That could be through providing a local number that encourages customers to get in touch. Alternatively, using greetings and systems means more calls get answered, and in a professional manner too.
  • Better overall performance: Once you have an efficient system set up, you can communicate easily, manage employees more effectively, and dedicate the time you save to other business activities.

Must-Have Features of Unified Communications Software

When looking for the best unified communications software of 2021, there are a few essential features you need to consider:

  • Communication options. Most platforms will give you access to voice calls, but you can also look out for video calls, fax, team chat, SMS, instant messaging, mass notification, and conferencing. Ideally, these features will launch from one interface to allow you to work flexibly.
  • Call management tools. Many UC software companies focus on voice capabilities. That means you can expect your extension to follow you to different devices and have options for call routing, as well as auto attendants to manage anything incoming.
  • Administration and management: It’s worth checking how much control you’ll have over your UC system. Many platforms will offer a console or web-based portal where you can see activity and availability, add users, and manage tasks.
  • Analytics and reports: What you really want to know is: Does this system work for me? It’s not asking too much to find a UC platform that tells you what your usage is and how effective your employees are through an analytics dashboard and reports.
  • Integration and customization: Plenty of UC software companies understand the personalized approach, which means they let you tweak features to suit your needs and add your logo to any interface you use. Another feature that should sit high on your list is integration with other applications, such as your CRM or calendar, as it improves your workflow.

The Cost of Unified Communications Software

As you’ll have seen from our reviews, pricing plans vary by company. There are some that provide free access to their software but with a restriction on the features. Others might charge for usage based on a license that gives you a certain number of minutes or extensions.

The pricing plans are typically annual or monthly subscriptions, although some companies offer up-front costs with no contract. The monthly fees are often based on user numbers and range from as low as $4 to as high as $50. Most plans relate to the size of your business and the features you can access.

Many of these companies offer quotations after consultations. That means the software will be tailored to your needs. However, you won’t know the full cost until you sign up. The majority do provide a free trial period or a demo, though, so you can see if they fit your company’s needs.
