With the increase in remote and hybrid teams, the move to cloud-based phone services has revolutionised the way we do business. Now, businesses of all sizes can access the telecom features necessary to make or take inbound, outbound or in-team phone calls from wherever there’s a good broadband connection.

These voice over internet protocol (VoIP) systems also offer a bunch of features to help you make the most of your communications and gain data-driven insights into sales and customer experience.

Read on to discover the key features of business phone systems and where you can get yours.

Essential Features of Business Phone Systems in Australia

Easy Setup

One of the key reasons businesses stay sat firmly on the fence when it comes to switching up their phone systems is a fear of disruption. No business wants their sales or support teams out of action for hours or even days while a new system is set up.

Look for a service provider that’s happy to assist with physical installation or cabling requirements and a system that can be used instantly without extensive training. A new office phone system should have a gradual learning curve, allowing teams across your organisation to quickly benefit from all the features of your new system.


System downtime can have negative knock-on effects for businesses of all sizes. That’s why you need to ensure that your in-office and remote workers have access to a stable internet connection before investing in a new phone system.

Next, you should look at the support offered by system providers – do they have a 24-hour helpdesk? Do they offer contingency for power outages or NBN outages?

Some providers offer automatic round-the-clock updates, providing system upgrades and patches while you work (or sleep). This can fix bugs before they affect your team.


Consider the short-term and long-term costs of your new business phone system before signing on the dotted line. While the price of the package and any associated hardware are important factors, make sure you calculate the cost of calls and any specific features that aren’t included by default.

Look for a provider that offers unlimited VoIP calls and video, and calculate your phone bill based on the number of users within your business.


From start-up success to market domination, your organisation has goals for growth – and your phone system should too. Explore options for upgrading your package as you grow, from switching to a hosted PBX system to adding more users, handsets and phone lines.

Ask about any early termination fees associated with upgrading or altering your package before the end of a set term. You want as much freedom as possible to customise your plan as you go. Your provider should be confident in supporting your changing business, whether you’re handling a hundred calls a day or several thousand.

Voicemail to Email

Voicemail is a crucial feature of any phone system, ensuring that customers and clients who can’t contact you immediately have a chance to log their queries. A PBX phone system makes this even more useful, sending voicemail messages directly to your inbox.

The benefits of this are twofold: firstly, it allows remote agents to check for and follow up voicemails from their own devices, ensuring that all messages are responded to promptly. Secondly, it lets you create a digital archive of voicemails, which can be used to understand developing relationships or issues, as well as for training and data analysis.

Auto Attendant

Decrease hold time and improve customer satisfaction by setting up an automated answering system. This feature greets callers with an automated message and uses voice recognition technology to triage their call.

By talking callers through a list of predefined options, the auto attendant can direct their call to the correct department, routing them to the answers they need faster. This feature saves time and money, cutting out the need for a dedicated phone receptionist and allowing multiple callers to be dealt with at once.


Worldwide mobile VoIP calls are predicted to increase by over 13% until 2025.

Make the switch from from physical handsets and allow agents to take calls from their computers, tablets or mobile phones. This promotes a remote or hybrid work style, as well as cutting down costs on physical hardware.

Audio while on Hold

Nobody likes being put on hold – but you can improve the experience with a custom playlist of calm-inducing music or even audio announcements. These can relay important information, such as telling callers where else they can go for help or advertising products and services.

Fax to Email

Reduce paper waste while you upgrade your phone system by opting for a fax to email feature. This converts incoming faxes to PDF files and sends them to your inbox, rather than printing them out. As with voicemail to email features, this has the added benefit of creating a data-rich archive for agents to refer back to.

Online Portal

A hosted PBX or cloud-based system should include an online desk for you to manage the system from. This will allow you to turn call features on and off, as well as create automatic reports to help you understand and manage your communications going forward.

This is the gateway to your company using data to drive growth, allowing you clear insight into KPIs, such as average call length, time in queue, handle time, resolution rate, cost per contact and the most common queries and effective scripts.
