The best corporate telephone systems simplify the process of setting up and maintaining software-based telephone systems, both in the workplace and for telecommuting employees.

So it’s no wonder that many organisations have switched from older hardware-based PBX telephone systems to these new software-based systems which take advantage of Voice over IP (VoIP) and high-definition video calling.

With the proliferation of smartphones in the workplace, it is now also possible to integrate these handheld devices into a cloud-based business phone system, enabling workers to make and receive calls regardless of whether they are in the office, on the road, or at home. 

The end result is a high-quality, e-commerce-friendly corporate solution for businesses of any size, providing the convenience of working from anywhere.

In addition, software phone systems support analytics and integrations, which provide actionable insights into customer behaviour and journey, while also streamlining the support and sales teams’ ability to interact with clients.

In this article, I will discuss some of the top VoIP solutions for the modern workplace and the mobile worker.

1. RingCentral MVP ☎️ – Leading Small Business Phone Systems in Australia

RingCentral MVP is a unified cloud-based communications platform for phone calls, video and audio conferences, and text messaging.

It is compatible with a wide variety of pre-existing hardware, and it is capable enough to utilise almost any mobile device as a softphone.

Features such as call tracking, recording, monitoring, and online faxing are, of course, common fare. In addition to audio conferencing and high-definition video, it also supports HD audio and voice conferencing via mobile, HD video conferencing and HD screen sharing.

The consolidated hub of customer service is equipped with routing via omni channels, agent management software, CRM interfaces, and data-driven insights. Many popular applications can be integrated, such as SalesForce, Zendesk, Microsoft 365, Oracle, Zoho, and others.

Discounts are available for groups of more than two users and are proportional to that number and the amount of features needed. The developer network provides access to application programming interfaces (APIs), allowing for a highly configurable telephony experience.

2. GoToConnect ☎️ – Runner-Up Small Business Phone System in Australia

GoToConnect lets businesses choose from a wide variety of features at different price points.

Impressively, it provides organisations with access to more than a hundred different calling, mobile, collaboration, and video conferencing options and solutions.

Encrypted personal meeting rooms, which are safe from prying ears, are available to clients in addition to the standard capabilities such as call distribution based on teams, geographical and time-based routing, and custom call routing.

GoToConnect positions itself as a Unified Communications as a Service (UCaaS) provider, promising that its customers don’t have to worry about anything from setup to upkeep or updates. However, the firm suggests that clients equip their networks with a Quality of Service-capable Ethernet switch, a commercial-grade router, and a firewall that is set up to accept HTTPS, HTTP, and UDP traffic.

GoToConnect is unique among VoIP companies in that it does not charge extra for advanced capabilities. Instead, costs are dependent on the size of the organisation, with custom plans created for enterprises with more than 100 workers.

Features like sophisticated ring options, call management, screen sharing, and personalised hold music are all at your disposal with Cloud PBX. Of course, with more functionality comes more room for error. Fortunately, GoToConnect provides comprehensive email and phone help in case any problems emerge.

3. Ooma Office ☎️ – Well-Regarded Small Business Phone Systems

Using the same internet connection you buy currencies with, Ooma Office is an online phone service for businesses that seeks to provide small organisations with the same quality of service as larger ones.

While Ooma may lack the bells and whistles offered by other VoIP providers, it is well-positioned as a cost-effective option for smaller businesses with limited resources.

The monthly cost per user is low when considering the features supplied. The system requires little effort to implement and use, since all of its functions are included in the single subscription plan.

You don’t get all the bells and whistles of the more expensive competitors out there, and the most glaring omission is support for integrating with customer relationship management (CRM) platforms.

4. 8×8 X Series ☎️ – Entry-Level Small Business Phone System

The 8×8 X Series is a cloud-based PBX phone system that provides all the features and functionality of a traditional PBX, even with the most basic subscription.

The entry-level plan, 8×8 Express, is equipped with a full suite of phone services, including comprehensive caller ID, auto-attendant functionality, call forwarding, call queues, and ring groups.

Integration with Google Workspace and Microsoft 365, as well as voicemail, team messaging, and voicemail transcriptions, are all available at this tier.

With the exception of Interactive Voice Response (IVR), the other features SMBs are likely to need are all included in the X Series X2 plan. Although the enterprise plans may be a problem, the pricing on this plan is fairly comparable with the competition.

5. Aircall ☎️ – Popular Small Business Phone System

Aircall is another simple-to-implement cloud-hosted company phone system option.

It grants your company a full communications centre solution for online, desktop, and mobile phone calls, video conferences, and messaging.

Aircall also includes a strong range of help desk, CRM, and productivity abilities to both enhance and support the way your support and sales teams handle calls. It does not limit your ability to approach and transfer customers, making it possible to set up a call centre in a matter of minutes.

As to be expected, there is also an analytics package for monitoring key performance indicators (KPIs) and determining where procedures might be optimised. Aircall offers a wide variety of connections with other applications in order to facilitate communication between different departments, including but not limited to SalesForce, Hubspot, Zendesk, Freshdesk, Zoho, and Slack. 

However, the scope of services needed will determine the final cost. Please be aware that in order to run this service, a minimum of three people must sign up.

6. Microsoft Teams Phone ☎️ – Affordable Small Business Phone System

Microsoft Teams Phone allows businesses (Best Virtual Credit Cards in Australia) to make calls from any Android or Windows, iOS, device to any location in the globe, with high dependability and high-quality audio guaranteed by the use of Microsoft’s cloud services.

If a customer currently has a subscription to Microsoft 365, adding Microsoft Teams Phone to their plan is a bargain. Support is available around the clock for the cloud-based phone system’s several sophisticated features including call transfer, auto attendants with multiple levels, and call queues.

One big problem of Microsoft Teams Phone is that the number of users is limited, depending on the subscription. The free and paid versions limit the number of participants in a meeting to 100 and 300 people respectively. If that is not a problem for your company, Microsoft Teams Phone is a fantastic addition to Microsoft 365.

7. Avaya OneCloud ☎️ – Unified Small Business Phone System

Avaya OneCloud is the company’s newest unified communications service, successor to the popular IP Office platform and extending the company’s existing Avaya IX Workplace and Contact Center offerings.

The service’s goal is to help you build a scalable solution on the cloud of your choice.

Avaya OneCloud is designed to function smoothly in a public cloud, making it an attractive option for small and medium-sized organisations (SMEs) which are keen to outsource their communications infrastructure management. This eliminates the need to manage software updates and hardware purchases.

Avaya’s OneCloud ReadyNow service allows enterprises with an existing private or hybrid cloud infrastructure to put up either a generic Avaya OneCloud or a tailored solution. Any necessary server hardware may be installed locally, or it can be hosted in one of Avaya’s data centres.

The Avaya OneCloud is a unified comms solution that incorporates all forms of communication into a single platform. The sheer scalability of the OneCloud solution by Avaya must be appealing, given the company has a proven track record in providing increased VoIP and UC services.

What Exactly Is a Small Business Phone System? (Essential Features)

The following functions are essential for VoIP phone systems in small businesses:

  • ✔️ Ability to make personalised greetings for people who call.
  • ✔️ A “virtual receptionist” computer system which answers incoming calls and routes them depending on the caller’s input.
  • ✔️ Transcribing voicemails into text messages.
  • ✔️ Business availability – defining a regular time frame during which customers may reach you by phone.
  • ✔️ Caller IDs may be programmed so that users’ outgoing calls will appear to originate from a certain number.
  • ✔️ Transmitting and receiving SMS messages.
  • ✔️ Whether or not the program allows for conference calls (involving more than two individuals).

These additions may help your small company better communicate both internally and externally with customers and partners. There is a vast variety of functions available for small company phone systems, but the ones highlighted below are the most crucial to consider.

Selection Guide

There are a few essential qualities that might make the selection of the right VoIP phone system for your small company less stressful and confusing. 

Like many other business considerations, financial constraints can be a source of stress. If you want to avoid losing money during a phone outage, you should prioritise options that have low upfront monthly fees, offer inclusive domestic minutes, provide multiple communication channels (so you do not have to pay extra to get these from other providers), and provide solid customer support.

The last thing you want to do when venturing into the world of VoIP is spend countless hours ensuring that all of the software platforms you use to operate your company are compatible with one another. That is why it is crucial to choose a service provider that can handle all kinds of connections, like a Swiss army knife. 

Keep an eye out for prebuilt connections to popular services like customer relationship management (CRM), email, web conferencing, internal messaging, and external messaging.

When a company outgrows a crucial piece of software and is forced to switch providers, the resulting upgrade and subsequent expenditures add up over time. As a result, you need a VoIP system that can grow with your business. 

Providers that allow an infinite number of users to be added are solid signs of this, as well as those that provide call queues, ring groups, a wide variety of administration capabilities, and tools that enable remote management of your business, such as internal messaging and video conferencing. As your company grows, security will also become more important.


I suggest the X2 plan from 88 and the Standard plan from GoToConnect, despite the fact that there are several excellent VoIP providers for small companies to choose from. 

If you own a small company, you should seriously consider either of these options since they are less expensive, have cutting-edge unified communications capabilities, and can be used effectively both in and out of the office.


What is the best phone system for my small business?

Identifying your specific requirements is the first step in selecting the optimal phone system for your organisation. If you only want to have a casual conversation with a small group of individuals, you may discover that a less expensive alternative offers all the features you need at a lower cost. 

However, if you need a business phone system for frequent, extensive usage by a large number of employees, you should investigate a more expensive package to make use of the more sophisticated features.

What hallmark signs make the best small company telephone system?

88’s X2 plan and GoToConnect’s Standard package are the best choices for smaller enterprises. Important features for every small firm to look for are: low cost, scalability, and prebuilt integrations with your current software stack. 

What is the most reliable business telephone system?

There are a plethora of options out there for phone service providers, but the first decision is whether or not to implement a Voice over IP (VoIP) or private branch exchange (PBX) system. VoIP lines are highly recommended since they make it possible to run a business from afar in a manner that is both versatile and cost-effective. 

Moreover, if you like to look at it another way, VoIP systems provide your company with all of the essential features that PBX systems do, so you are not giving up anything by switching. The service you end up going with should be selected according to the scope and requirements of your organisation. 

What is the average price of a phone system for a small business?

The price of a phone system for your small company may be kept low. A VoIP phone system might cost anywhere from $15 to $200 per user, per month, depending on your needs and the makeup of your staff.

The options we examine in depth in this study are priced between $30 and $63 per user, per month, and are designed with small enterprises in mind.

How do I install a telephone system for a small company?

A small company phone system should not be difficult to set up. There are four main requirements for a properly functional VoIP phone system:

  1. If you own a small company, you need to choose a service that fits your budget and your demands, and then activate your account by following the provider’s particular instructions.
  2. If you are going to utilise IP desk phones, the next step is to get them set up. Connecting the IP phone’s handset to the base is as simple as plugging in the included cable. Connect your phone to your router using the WAN connector on the back of the device. If you are considering a VoIP system, remember that it might include apps which you can use it on your computer, tablet, or smartphone, in addition to your regular desk phone.
  3. You can migrate your current toll-free number into your new business phone system if you already have one.
  4. Make your phone system exactly what you need it to be for your company by tweaking the settings to your liking. When you are in charge of a company’s phone system, you get to make all the important decisions about who gets which extensions and what permissions.

How does VoIP differ from a conventional PBX system?

Simply said, a VoIP system makes and receives calls via the internet, whereas a classic PBX system relies on a physical telephone connection. While both PBX and VoIP allow for simultaneous call reception, the former relies on an on-premise digital switchboard while the latter makes use of a remote server.
