Editor's note: Looking for a cloud phone system and PBX for your business? If you're looking for information to help you choose the one that's right for you, use the questionnaire below to have our partner site, BuyerZone, provide you with information from a variety of vendors for free:

Cloud-based phone systems are now increasingly replacing old PBX (Private Branch Exchange) hardware, and can offer a much more versatile performance while including a rich range of features as standard. 

Better still, pricing works out as much more efficient as you are paying for what you use, rather than having to invest in expensive on-premises hardware. This means that even small businesses can now access VoIP services and phone system features normally only enterprise companies could afford to build.

The result is that a small business can have a cloud-based phone system that also provides Unified Communications as a Service (UCaaS), for keeping all messaging, calls, and video conferencing working from the same platform. 

On top of this, small businesses can even use cloud-based contact centers by utilizing Contact Center as a Service (CCaaS) provisions which are sometimes built into existing cloud-based phone systems.

Overall, cloud services have been transforming and revolutionizing the telecoms industry and the range of services that can be provided and made accessible. As we move into 2020, here we'll feature the best in cloud phone systems.
