If you’re running a small business in Melbourne and still relying on a traditional landline, you may already be aware that the clock is ticking. Australia’s copper phone network is being decommissioned, and with the PSTN switch-off now complete across most of the country, the question isn’t really whether to move away from traditional landlines — it’s what to move to, and when.
For most Melbourne small businesses, the choice comes down to VoIP (Voice over Internet Protocol) versus keeping some form of traditional phone service through the NBN. This guide breaks down how the two compare across every dimension that matters for a small business: cost, call quality, features, reliability, scalability, and future-proofing — so you can make a fully informed decision for 2026 and beyond.
First, What’s Actually Changed?
Before comparing the two options, it’s worth understanding the landscape in 2026.
Traditional copper landlines — the PSTN (Public Switched Telephone Network) that has carried Australian phone calls for over a century — have been fully decommissioned by Telstra. If you were on a traditional landline, you’ve already been migrated or disconnected. The “landline” option that exists in 2026 is a voice service delivered over the NBN — either through a VoIP service bundled with your NBN plan, or through a dedicated voice-grade NBN service.
In other words, almost all phone services in Australia are now VoIP at the infrastructure level. The distinction in 2026 is between:
- NBN-bundled voice services — a basic phone line included with your NBN plan, typically managed by your telco and designed to replicate a traditional landline experience
- Standalone VoIP / Cloud PBX services — independent VoIP platforms that give you full control over your phone system, features, and configuration
For this guide, “landline” refers to the NBN-bundled voice service, and “VoIP” refers to a dedicated standalone VoIP or cloud phone system.

Cost Comparison
For most small businesses, cost is the first question. Here’s how the two options compare.
NBN-Bundled Voice (Landline-Style)
A basic voice service bundled with an NBN business plan typically adds $10–$30 per month per line. Local and national calls are usually included; international calls are charged per minute. You get one number, one line, and limited features. For a small office with low call volume, this is the cheapest entry point.
The hidden costs, however, add up. Calls to mobiles — which make up the majority of calls for most businesses in 2026 — are often charged separately. Additional lines mean additional monthly fees. Any features beyond basic call forwarding may require upgrades.
Standalone VoIP / Cloud PBX
VoIP services for small businesses in Melbourne typically range from $20–$60 per user per month on a hosted PBX platform, including unlimited local, national, and mobile calls. For a business with three to ten staff making regular calls, the per-minute savings on mobile calls alone often justify the switch within the first few months.

Hardware costs vary: IP handsets range from $80–$300 per unit, though many businesses now use softphones (apps on computers or smartphones) that eliminate hardware costs. Setup fees vary by provider — some charge nothing, others charge $200–$500 for configuration and onboarding.
Bottom Line on Cost
For a single-person operation making light call volumes, an NBN-bundled voice service may be marginally cheaper. For any business with two or more staff making regular calls — particularly to mobile numbers — standalone VoIP almost always delivers better value within the first year.
For growing teams, the cost efficiency becomes even more apparent. Our guide on VoIP setup for small businesses explains how multi-user systems reduce per-user costs while adding functionality:
Call Quality
Call quality is a legitimate concern for businesses considering VoIP, and it’s worth addressing directly.
NBN-Bundled Voice
Because the telco manages both the NBN connection and the voice service, they can prioritise voice traffic on their network, resulting in consistently good call quality in most cases. This is a genuine advantage of the bundled approach — you’re not competing with your own internet traffic for bandwidth.
Standalone VoIP
VoIP call quality in 2026 is excellent — provided your NBN connection is stable and your network is properly configured. The two main variables are your internet connection quality and whether your router is configured to prioritise voice traffic (QoS settings). On a well-configured NBN 50 or NBN 100 connection, a standalone VoIP call is indistinguishable from a traditional landline call for most users.
The codec used also matters: G.711 delivers the highest quality audio; G.729 compresses more aggressively for lower-bandwidth situations. Most reputable VoIP providers support both and automatically select the most appropriate option.
Where VoIP call quality can suffer is on poor-quality NBN connections — particularly FTTN services with long copper runs — or in offices with heavily congested networks and no QoS configuration. These issues are solvable, but they require attention.
Bottom Line on Call Quality
Both options deliver good call quality in most Melbourne business environments in 2026. Standalone VoIP requires slightly more attention to network configuration but is not inherently inferior — and for many businesses, the HD voice quality available through modern VoIP codecs is actually better than the legacy PSTN audio they’re used to.
Features
This is where standalone VoIP separates itself most clearly from the bundled voice option.
NBN-Bundled Voice
A bundled voice service is designed to replicate the traditional landline experience. You get a phone number, basic call forwarding, voicemail, and caller ID. Some providers offer hold music and call waiting. What you don’t get is a phone system — no auto-attendant, no call queues, no ring groups, no call recording, no voicemail-to-email, no CRM integration.
For a sole trader or a business that simply needs a phone number to receive occasional calls, this is perfectly adequate. For any business that manages inbound call flow, has multiple staff handling calls, or wants to project a professional image through its phone system, it falls significantly short.
If you’re unsure whether your business infrastructure is VoIP-ready, our VoIP setup for Melbourne businesses guide covers network requirements and best practices:
Standalone VoIP / Cloud PBX
The feature set available through modern VoIP platforms is transformative for small businesses. Standard inclusions across most platforms include:
Call management: Auto-attendant (press 1 for sales, press 2 for support), call queues, ring groups, call routing by time of day, simultaneous ringing across multiple devices, and call transfer between extensions.
Productivity features: Voicemail to email (receive voicemails as audio files in your inbox), call recording, detailed call logs and reporting, hold music and custom messages, and conference calling.
Mobility: Because VoIP is internet-based, your business number follows you. Staff can take calls on their mobile phone, laptop, or home office handset using the same extension and number — critical in Melbourne’s increasingly hybrid work environment.
Integration: Most modern VoIP platforms integrate with CRM systems (Salesforce, HubSpot, Zoho), helpdesk software, and productivity tools — logging calls, displaying customer records when a call comes in, and streamlining workflows.
Multiple numbers: Geographic Melbourne numbers (03), 1300 numbers, international numbers — all manageable from a single platform.
Bottom Line on Features
For any small business that wants to manage calls professionally, support hybrid or remote work, or scale its communication system as it grows, standalone VoIP is not just better — it’s in a different category entirely.
Reliability and Uptime
Reliability is the most common concern raised about VoIP, and it deserves an honest assessment.
NBN-Bundled Voice
A bundled voice service shares the reliability of your NBN connection. If your NBN goes down, your phone goes down. Many providers offer a failover option — calls divert to a mobile number if the NBN connection drops — but this isn’t always included by default and may require configuration.
Standalone VoIP
Standalone VoIP has the same NBN dependency — if your internet goes down, your VoIP service goes down. However, modern VoIP platforms offer sophisticated failover options: calls can automatically route to mobile numbers, other offices, or an answering service when the primary connection fails. Some businesses maintain a 4G/5G backup connection specifically to keep VoIP operational during NBN outages.
It’s also worth noting that VoIP platforms are cloud-based — the service itself runs on redundant data centres with high uptime guarantees (typically 99.9% or better). The vulnerability is your last-mile internet connection, not the VoIP platform.
Emergency Services (000)
One genuine consideration: VoIP services handle 000 calls differently from traditional phone services. You must register your address with your VoIP provider for emergency services to use location information when you call 000. This is a legal requirement in Australia and all reputable providers support it — but it’s worth confirming during setup, particularly if your business moves premises.
Bottom Line on Reliability
Both options share the same fundamental dependency on your NBN connection. Standalone VoIP offers more sophisticated failover options, but requires more deliberate configuration. For businesses where phone availability is genuinely critical, a 4G backup connection combined with VoIP failover routing delivers higher practical uptime than either option alone.
Scalability
Growth is the goal for most small businesses. How each option scales matters.
NBN-Bundled Voice
Adding a line means calling your telco, waiting for provisioning, and paying more per month. Adding five lines means five separate services, five sets of fees, and no unified management. There’s no concept of extensions, ring groups, or shared call handling — each line is independent.
Standalone VoIP
Adding a user to a cloud PBX takes minutes — you provision a new extension in the platform dashboard, configure a softphone or IP handset, and you’re done. No hardware installation, no technician visit, no waiting period. Scaling from three users to fifteen is the same process as scaling from one to three.
This also works in reverse: if your business contracts seasonally or you need to reduce headcount, removing users is equally straightforward. You pay for what you use.
Bottom Line on Scalability
Standalone VoIP scales with your business in a way that bundled voice services fundamentally cannot. For any Melbourne small business with growth ambitions, this flexibility is a significant practical advantage.
Setup and Management
NBN-Bundled Voice
Setup is typically handled by your telco as part of your NBN connection. Plug in the phone, it works. Management is minimal — you call your provider to make changes. Simple, but inflexible.
Standalone VoIP
Initial setup requires more effort: choosing a provider, configuring the platform, provisioning handsets or softphones, setting up call routing, and testing. Most reputable providers offer onboarding support and many Melbourne IT services companies can handle the setup entirely. Ongoing management — changing routing, adding users, updating messages — is done through a web dashboard and is genuinely straightforward once configured.
Bottom Line on Setup
Bundled voice wins on simplicity. VoIP wins on control. For a business owner who values being able to manage their own phone system without calling a telco, VoIP’s self-service dashboard is a significant advantage once the initial setup is complete.
Which Should Melbourne Small Businesses Choose in 2026?
The honest answer depends on your specific situation, but the directional guidance is fairly clear:
Choose an NBN-bundled voice service if:
- You’re a sole trader or micro-business with minimal call volume
- You need a phone number but not a phone system
- You want the absolute simplest, lowest-maintenance option
- Your budget is genuinely constrained and you don’t make many mobile calls
Choose standalone VoIP if:
- You have two or more staff who handle calls
- You want professional features — auto-attendant, call queues, voicemail to email, call recording
- You support hybrid or remote working and need staff to be reachable on their business number from anywhere
- You make frequent calls to mobiles (where per-minute costs on bundled services add up quickly)
- You anticipate growth and want a phone system that scales with you
- You want to integrate your phone system with your CRM or other business tools
For the overwhelming majority of Melbourne small businesses in 2026, standalone VoIP is the better choice — not marginally, but meaningfully. The cost savings on mobile calls, the professional features, the flexibility for hybrid work, and the scalability combine to deliver a communication system that a bundled voice service simply cannot match.
Making the Switch: What to Expect
If you’re moving from a bundled voice service to standalone VoIP, the process is more straightforward than most people expect:
Number porting — you can keep your existing business number. Local Number Portability (LNP) allows your number to be transferred to your new VoIP provider, typically within 2–10 business days.
Hardware — you may be able to reuse existing IP handsets if they’re SIP-compatible. Otherwise, quality IP handsets start from around $80, and softphones (apps on existing devices) cost nothing.
Downtime — with proper planning, there’s no downtime during the switch. Your existing service remains active until the port is confirmed and your new system is tested.
Support — choose a provider with Australian-based support and clear onboarding documentation. The initial configuration is the most complex part; once set up, day-to-day management is straightforward.
Conclusion
The VoIP versus landline debate has largely been settled by circumstance — traditional landlines no longer exist in Australia, and every business phone service in 2026 is, at some level, a VoIP service. The real choice is between a basic, telco-managed voice line and a full-featured, independently managed VoIP platform.
At Computer Cures, we’ve seen firsthand how this shift is reshaping the way Melbourne small businesses communicate. For businesses that want to operate professionally, support a mobile workforce, manage costs intelligently, and build a phone system that grows with them, the case for standalone VoIP has never been stronger. The technology is mature, the pricing is competitive, and the feature gap between VoIP and bundled voice has never been wider.
The question in 2026 isn’t whether VoIP is good enough for your business. It’s whether a basic bundled voice service is good enough — and for most businesses, the honest answer is no.
