1. Nexgen

Best overall small business phone system

Nexgen has strong network running speeds to ensure that your phone system’s never down, and customer reviews often cite Nexgen’s friendly customer service as a big pro.

3. Ooma

Best low-cost option

Ideal for small businesses without dedicated IT departments, the Ooma Office phone system is ready to go from the box, and can be set up by anyone within 15 minutes.

It also comes with over 35 features to help support your small business, including a virtual receptionist to take calls while your staff are busy, and remote extension dialling – which enables callers to reach your employees’ cell phones while they’re working remotely. While not quite as feature-rich as RingCentral Office, Ooma Office balances that out with a more affordable price tag.


  • Rated #1 in reliability by readers of PC Magazine
  • Free mobile app enables staff to access your business phone system on the go
  • 30-day free trial
  • Comsource also provides internet, so there’s the option to roll both services into one

X Cons:

  • Connection via mobile app could be stronger during peak hours
  • Doesn't come with as many features as RingCentral Office

How much does Ooma cost?

Ooma is our favourite low-cost phone system for a reason! It's cheapest package is very affordable at $19.95 per month, though you'll need to pay for the Pro plan if you want additional functionalities like video conferencing, call recording, and a desktop app. Don't fret, though, because Ooma Office Pro isn't likely to break the bank either:

PlanPrice (per user, per month)
Ooma Office$19.95
Ooma Office Pro$24.95

4. Comsource

Best for very small offices

Comsource is another Australia-based company that more than holds its own against international competitors. A one-stop phone shop, ComSource provides conference, corded, and cordless phones, as well as a mobile app and state of the art VoIP technology. 

As well as this, our research found that customers particularly love ComSource's dedicated account managers, who are on hand to help with any support you need – which is ideal for small offices that are new to VoIP technology!


  • Swift service – ComSource customers rate the speedy technical support they receive when needed
  • Phone systems come with the option of a powerful softphone app, so you can take calls on-the-go
  • A dedicated customer service agent means you always know the right person to speak to, saving you time spent on hold

X Cons:

  • Detailed pricing is only available on request

How much does Comsource cost?

Like Nexgen, Comsource asks that you get in touch for a bespoke quote in order to find out how much its phone system will cost for your small business. However, we do know that Comsource's prices start at $22.50 per line, per month.

Still unsure which phone system is best for your small business? No dramas – we can help you out. All we need from you is some quick details about your business, and we’ll match you up with trusted phone system suppliers that best suit your requirements. They’ll then be in touch with quotes tailored to you. It’s quick, easy, and free – why not get started?

5. 8×8

Best for small to medium-sized businesses

8×8 is a well-respected phone systems provider with a broad range of plans available. That’s why it’s a great choice for businesses that might be small now, but anticipate growth in the near future. That's because 8×8 makes it especially easy to upgrade your cloud-based phone system as you grow, while benefiting from brilliant training and setup advice

We also recommend 8×8 to businesses that are on the up because it's a little more expensive than your average small business offering. However, the array of sophisticated features on offer will likely make it a worthwhile investment.


  • Easy to upgrade as you need
  • Great onboarding process – you and your team don’t need to know anything about VoIP to get started
  • Packed with features, including video meetings and unlimited international calls

X Cons:

  • Some reviews complain of patchy customer support
  • One of the more expensive providers (but you do get a lot of bang for your buck)

How much does 8×8 cost?

You'll notice that 8×8's more advanced plans are quite expensive. But you will get a lot of bang for your buck with them, including full UC capabilities (video meetings and instant messaging) and unlimited calling to 14+ countries. 8×8's cheapest plan is fairly generous too, with features such as auto attendants and unlimited calls, but you will miss out on some of the more exciting features that other systems provide for less.

The fact of the matter is that comparing quotes that have been tailored to your unique needs makes spotting the phone system that will work best for you, and so finding the perfect option for your small business, much easier.

They’ll then be in touch directly with custom quotes. We’ll do all the legwork, leaving you to sit back and choose the option that’s right for you.


How can phone systems improve my customer service? 

The latest business phone systems can be integrated with CRM (customer relationship management) software, which can help to improve your customers’ experience. The best CRM software will ensure all of your sales leads are effectively managed and followed up, helping to create perfect harmony on both sides of the phone.

Call distribution features keep your customers from waiting too long, ensuring their call is answered quickly and by the right person. Some phone systems can also provide pre-recorded welcome messages that keep your customers informed. 

remote working is part and parcel of working for a small business – fortunately, mobile number extensions enable your employees to answer the phone while they’re away from the office.

What are VoIP telephone systems?

VoIP (Voice over Internet Protocol) transmits phone calls over the internet rather than the telephone network, making them more reliable, flexible, and customisable than traditional office phones. The best VoIP solutions in Australia include Comsource, 8×8, and RingCentral.

How much does a small business phone system cost?

Most small business phone system suppliers charge a monthly fee, which can range anywhere between $20 and $50 per user, depending on the number of features you’d like to use. You’ll also need to consider additional set up fees, which can reach up to $200 per phone system.
