The way we work is changing as we continue our transition into the post-pandemic enterprise era. 

Complete remote working might be down, but hybrid work continues to remain popular in organizations around the world, with over half of workers still working at least 3 days from home, according to Pew Research

As hybrid working becomes the new norm, organizations need to make sure they have a solid organizational network to keep business communications as efficient as possible with employees working remotely. 

That’s why cloud phone systems continue to be essential for enterprises big and small. 

What are PBX cloud phone systems? 

A cloud phone system, also known as a cloud PBX, hosted PBX, or virtual PBX, is a business phone service that operates over the internet rather than traditional phone lines. Here's a breakdown of how it works. 

Unlike traditional systems with on-site hardware, cloud phone systems are hosted by a service provider in secure data centres. This eliminates the need for your company to buy and maintain its own equipment.

They rely on Voice over Internet Protocol (VoIP) to transmit voice calls and data. This means your calls travel over your internet connection instead of dedicated phone lines.

You can also use a variety of devices with a cloud phone system, including traditional IP phones, smartphones with apps, computer software, or even regular phones with adapters.

Over the past few years, cloud phone systems have transformed from being a cost-saving opportunity for modern business communications to a necessary investment. 

With cloud phone systems, companies can access future-proof communication tools that empower staff in any environment, including remote and hybrid work.

Benefits of PBX cloud systems 

There are several advantages to cloud phone systems compared to traditional phone lines. For one, Cloud-based systems often mean lower upfront costs since there's no need to buy and maintain physical equipment. You also typically pay a monthly subscription fee which can be more predictable than traditional phone bills with per-minute charges.

Cloud phone systems are also perfect for today's remote work environments. Employees can use the system from anywhere with an internet connection, whether it's the office, home, or on the go.This flexibility can improve productivity and collaboration.

Another major benefit is the ease of scaling your phone system up or down as your business grows.

With traditional systems, adding new lines can be complex and expensive. Cloud systems allow you to easily add or remove phone lines as needed.

On top of these benefits, cloud phone systems often come with a range of features that can enhance your business communication. These can include auto attendants, voicemail to email, call forwarding, video conferencing, and integrations with other business tools like CRM software.
