How to Choose the Right Business Phone System?
The right business phone system comes down to three things: how many people need it, how many calls you handle, and how fast you’re growing. Match those to a landline, an on-premise PBX, or a cloud VoIP setup, and the choice makes itself. Upgrading is still the task small business owners put off until it’s too late, though, because it rarely feels urgent until communication breaks down: orders delayed, customers left waiting, calls going unanswered. Keep your lines of communication clear, and the rest of the business tends to fall into place.
Whether you’re starting a business from scratch or your small business has simply outgrown a simple landline, the real question comes down to a handful of factors: the options in front of you, the range of services and features actually worth paying for, and the choice that keeps your business running smoothly instead of forcing you to pick between decent quality and a reasonable price. A phone system, at its core, supports professional voice calls that make you sound like the business you actually are. But the best business phone system goes further, weaving in video, email, social media and instant messaging as everyday communications tools, because no customer wants to wait on hold anymore.
This is where unified communications, or a proper unified communications solution, earns its keep: reliable, seamless, clear communication that’s essential if you want customer experience to stay high. Getting your head around the types of phone systems out there, from a compact setup for one office to a system built for a growing team, is essential groundwork, because complex needs only get more complex as a business grows, and whatever you pick needs room to grow with you and boost productivity.
Types of Business Phone Systems
No two offices run their calls the same way. Some teams are happy with a handset that’s barely moved in years, while others need calls following them from a desk to a job site to a laptop at home. Here are the main options and who each one suits best.
Landlines (PSTN & PBX)
Traditional landlines use a physical connection to a fixed location, like your home or office, purely to support calls. In Australia, most modern phone systems now transmit voice calls using VoIP, or voice over IP technology, and some internet plans even come with a fixed phone service automatically included.
A landline gives you a fixed number that customers can call directly, plus the option to forward calls to another number when no one’s at the premises. It’s one of the most common choices for a local retail shop with simple needs, especially if you don’t expect multiple people on calls at the same time.
The catch: standard PSTN lines aren’t built for growing teams, since you’d need a separate line for every employee, which quickly turns cumbersome and expensive. That’s where PBX systems historically stepped in, using on-site hardware to create multiple phone extensions and handle call forwarding across a whole telephone system. It was genuinely popular in the past, but as cloud services have taken over, fewer providers still offer this ageing technology.
PABX & On-Premises Phone Systems
A PABX (Private Automatic Branch Exchange) takes that idea further, creating a shared communications system where more than one team member can receive and make calls at the same time, through a single incoming number or a limited group of numbers. Done well, a PABX solution can:
- Handle multiple incoming and outgoing calls for several people at once
- Manage a large volume of calls efficiently, whatever the size of your business
- Route calls to the right person at the right time
- Help you meet customer expectations and deliver a positive experience
Traditional PABX systems run on on-site hardware (sometimes called IP PBX), which means large initial outlays up front, better suited to on-premise deployments than most SMEs. The advantage is that you own and keep full control of your system; the trade-off is that you, or your provider, carry the responsibility for maintaining it. Many businesses have since moved on to cloud-based PABX and other cloud calling solutions, which offer greater flexibility without the hardware overhead.
VoIP
VoIP, or Voice over Internet Protocol, is the modern solution most business communications now run on, and it comes with real advantages over both landlines and on-premise PBX. A VoIP system uses your existing internet connection to receive and route calls, so a small business doesn’t need much beyond a PC, laptop, or smartphone with a headset, though you can also buy VoIP-enabled handsets if you’d rather keep the look and feel of a normal office phone.
VoIP usually carries a lower service charge than a fully-featured PBX system and connects remote workers with ease. It can also be run as either an on-premise (managed) or cloud-based service, depending on how much control versus convenience you want. The one caveat: you’ll need a stable, reliable internet connection to get consistent service out of it, so treat your broadband as priority one before anything else.
Cloud Calling & Cloud PABX
Cloud calling, or cloud telephony, relies on VoIP technology to transmit phone calls across the internet instead of through on-site hardware. When it’s integrated with cloud-PABX or a full unified communications solution, you unlock real flexibility for the whole business. Cloud PABX combines the reach of traditional PABX with the freedom of the cloud, so a business with several locations can manage every site without on-premises boxes. Because it’s hosted off-site, cloud calling brings:
- Predictable monthly fees and lower setup costs
- Remote access for hybrid teams, with built-in security and automatic updates
- Everyday devices, like mobiles and laptops, connecting straight into your cloud system
- Hunt group features that automatically distribute incoming calls across a group, instead of relying on one line or person
- Room to scale as your business grows, with no hardware to rip out
This isn’t reserved for big players either. A boutique studio with four staff and a professional services business with fifty are both, technically, businesses of any size, and both can lean on the same cloud-based communications solutions, unified communications packages, and genuine scalability as they grow.
Virtual Phone Systems
Traditional systems are becoming less popular as online, app-based options take over. Virtual phone systems let you route your main business number to other lines, like an employee’s mobile, which is genuinely useful for small remote teams or a hands-on boss who’s often out of the office. Usually installed as a mobile app, they add extras like voicemail, virtual receptionists, and call screening, plus a different ringtone so you know whether it’s a work call or a personal one. Worth knowing: this isn’t a fully online phone system, since calls still run over your provider’s network behind the scenes.
Mobile Phones for Business
Plenty of businesses, especially trades or teams who are always on the move, rely on mobile phones for every call, and it genuinely makes sense in those cases. The upside is convenience, flexibility, and no extra devices or services to pay for. The downside is real too: using a personal mobile number for business calls mixes work and personal life, and it can be hard to separate them later. If you’d rather keep a professional profile while staying reachable, look for unified communications solutions that let you access an integrated business system from your own phone, without handing out your personal number.
Key Features to Look for in a Business Phone System
Picking a phone system isn’t just about a dial tone. The real difference between a setup your team actually uses and one that gets ignored comes down to which features are built in properly. Here’s what’s worth having on your shortlist:
- Auto-Attendant (IVR): Also called a virtual receptionist, it greets callers the moment they dial in and routes them to the correct department, or lets them select from a list, without anyone lifting a finger. It smooths out your workflow and cuts down on missed calls.
- Softphone Apps: Lets employees handle business calls through a mobile or desktop interface instead of a physical handset, so your team can work from anywhere without losing the professional line.
- Voicemail-to-Email: Converts voicemail messages into audio files sent straight to an inbox, tagged with the caller’s details. Tie it to your CRM and voicemails link straight to client accounts.
- CRM Integration: Connects your customer data with tools you’re likely already using, like HubSpot or Salesforce, so call activity and customer records live in one place.
- Call Queues: Places incoming calls into an orderly line and lets callers know their position and estimated wait time, so nobody’s left guessing while volumes spike.
- Call Forwarding: The most basic feature on this list: the ability to forward calls from a central number to whichever staff member or department should be taking it, and it’s handy for redirecting old numbers too.
- Call Parking: Think of it as an advanced hold. Calls get assigned a numbered bay, and any employee with access can pick it up and continue the call, useful when several people need to work an issue together.
- Call Transfer: Works across most analogue and digital phone services, using hunt groups to route calls to multiple numbers. On VoIP this capability is usually a no-cost feature; on a landline it can incur standard-rate charges.
- Music on Hold: A small touch that makes a client’s wait more bearable. Most managed services offer it as a simple option; running your own service means factoring in licensing unless you use copyright-free music.
- Conference Calls: Important for any collaborative remote team or a business whose department heads sit across different locations. VoIP makes the service the easiest to access, letting anyone join with just an internet connection.
- Call Recording: Useful for training, KPI tracking, and dispute resolution. Linked to a CRM system, it lets you log and pull every call from a single, central location whenever you need it.
- Call Logs: A simple way to track caller ID, duration, and time to answer for every incoming call, recorded automatically in real time, with no manual entry required.

What to Consider When Choosing Your Business Phone System
Every recommendation about the best business phone system depends on what matters most for your own business, which is why it’s worth asking yourself a few honest questions before committing to anything:
- How many people need access, and does that call for a solution that can manage high call volumes without buckling?
- Can it scale easily to support real business growth, without forcing a full rebuild later?
- Which advanced features would be genuinely useful? Think call routing, voicemail-to-email, and video calling.
- Should it integrate with your existing collaboration tools, so nothing lives in a separate app?
- What about up-front costs versus ongoing costs, flexibility of plans, and whether there are lock-in contracts?
- Could your business benefit from additional numbers, like a 1300 number, to sound more established?
Whatever you land on, make sure it covers every point above, with real support behind it when something goes wrong.
