VoIP Cost Calculator
Business VoIP is priced per user per month, with call rates, handsets and porting sitting outside that number. This calculator estimates the monthly and setup cost for your team.
Count every person who needs an extension, including part timers.
Heavy outbound calling changes which plan type is cheapest.
Number porting is the step that causes the most grief in a VoIP migration. Porting an existing landline or 1300 number typically takes five to fifteen business days for a simple port and considerably longer for a complex one, and it cannot be rushed. Book the port well before you plan to cancel the old service, and never cancel the old service first.
💰 Ways to save
- Analyse three months of actual call records before choosing a plan type. The choice between pay as you go and unlimited is arithmetic, not preference, and most businesses guess wrong in both directions. A team making occasional short calls often overpays substantially on unlimited seats, while an outbound sales team on pay as you go can spend more in call charges than an unlimited plan would have cost outright. Your existing provider must be able to supply itemised call data, so ask for it and do the calculation.
- Right size the licence tier per user instead of applying one tier to everyone. VoIP platforms sell in tiers, and the higher tiers exist for people who need call recording, queueing, analytics or CRM integration. A warehouse phone, a meeting room and a part time administrator do not need the same licence as a sales representative. Auditing seat by seat commonly removes fifteen to thirty percent of a monthly bill, and it takes an hour.
- Buy handsets outright rather than renting, or use softphones and headsets where the role allows. Purchase is roughly $120 to $400 per handset against rental of $8 to $20 per month, so rental typically overtakes purchase within about two years while leaving you owning nothing. Many roles do not need a desk phone at all, since a softphone on a laptop with a good USB headset performs the same function, costs a fraction and travels with the user.
- Confirm your internet connection and network are ready before you migrate, because most VoIP complaints are network problems misattributed to the phone provider. VoIP needs low jitter, low packet loss and consistent latency far more than it needs high bandwidth, so check the connection type, ask whether quality of service can be configured on your router to prioritise voice traffic, and make sure the router itself is capable. Fixing this after a bad go live costs both money and internal credibility.

Understanding voip costs in Australia
What business VoIP costs in Australia in 2026
Business VoIP is sold per user per month, and the Australian market in 2026 sits in a reasonably tight band. Entry level hosted plans with basic calling and voicemail run roughly $15 to $25 per user per month. Standard business plans including unlimited local and national calls, auto attendant, call transfer, hunt groups and mobile applications typically run $25 to $40 per user per month. Plans that include unlimited calls to Australian mobiles sit around $35 to $55. Contact centre tiers with queueing, skills based routing, recording, wallboards and reporting run $50 to $90 per agent per month. SIP trunking, where you keep an existing on premise PBX and only replace the lines, is cheaper again at roughly $10 to $25 per channel per month, though it requires the PBX to be capable and supported. Setup costs are separate and are discussed below.
Per user pricing and what falls outside it
The monthly seat price is the headline, but several real costs sit outside it. Handsets are the largest, at $120 to $400 each to buy outright depending on whether you want a basic two line phone, a mid range device with a colour screen, or a receptionist console with expansion modules. Rental is commonly offered at $8 to $20 per device per month, which is convenient for cashflow but generally costs more than purchase within about two years and leaves you owning nothing at the end. Setup and configuration is often charged as a one off, either per user or as a project fee, and can run from a few hundred dollars for a small straightforward deployment into the low thousands where call flows, IVR menus and integrations are involved. Number porting may attract a fee per number. Additional inbound numbers, particularly 1300 and 1800 services, carry their own monthly fee plus inbound call charges, which is a cost most businesses forget applies to the receiving end.
Pay as you go against unlimited
Australian VoIP providers offer both, and which one wins is purely a function of your call profile. Pay as you go plans carry a lower monthly seat price and then charge per call, typically around 8 to 12 cents for an untimed local or national call and 15 to 25 cents a minute to Australian mobiles, with international rates varying widely by destination. Unlimited plans charge more per seat and remove per call charges within defined limits, and those limits matter because most unlimited plans carry a fair use policy rather than being genuinely unlimited. The right way to decide is arithmetic. Obtain three months of itemised call data from your existing provider, split it into local and national, mobile and international, and price it against both structures. Businesses with a small number of heavy callers frequently find the answer is a mixed deployment, putting the heavy users on unlimited and everyone else on pay as you go, which most providers will accommodate.
Porting, and the migration risk nobody plans for
Number porting is the part of a VoIP migration that most often goes wrong. Porting moves your existing number from the old carrier to the new one, and it requires the old carrier's cooperation, matching account details, and a defined process with regulated timeframes. A simple port of a single number typically takes five to fifteen business days. A complex port, meaning multiple numbers, a number block, or a number bundled with other products, takes considerably longer and is more prone to rejection over mismatched details. Two rules avoid almost all the pain. Never cancel your existing service before the port completes, because cancelling releases the number and it may be unrecoverable. And schedule the cutover with a fallback, keeping call forwarding in place during the transition.
Your internet connection is the real determinant of quality
Most complaints about VoIP call quality are network problems rather than provider problems, and the distinction matters because switching provider will not fix them. Voice traffic is small in bandwidth terms, roughly 100 kilobits per second per concurrent call, but it is extremely sensitive to jitter, which is variation in packet arrival timing, and to packet loss. A fast connection with inconsistent latency will sound worse than a slower connection with stable latency. The practical requirements are a business grade connection with reliable performance, a router capable of quality of service configuration so voice traffic is prioritised over file transfers and video, adequate upload capacity for the number of concurrent calls you expect, and ideally a separate voice network or VLAN in larger deployments. Ask your provider to perform a network readiness assessment before migration rather than after, because diagnosing this once staff have formed an opinion about the new phone system is a harder problem than the technical one.
Contracts, features and choosing well
Contract terms vary from month to month with no commitment through to thirty six month agreements with hardware bundled in. Longer terms buy a lower rate and subsidised handsets at the cost of flexibility, and early termination provisions can be substantial. On features, be sceptical of long inclusion lists and identify the four or five capabilities you will genuinely use: an auto attendant that routes callers properly, hunt groups so calls do not go unanswered, mobile applications, voicemail to email, and call reporting if you manage a phone team. Recording is worth having where compliance requires it, but check retention, storage costs and the rules on notifying parties. Finally, ask what happens to inbound calls if your internet fails.
Next steps
Use the estimate above as a monthly bracket, then get three months of itemised call data and ask two providers to quote against it, showing seat licences by tier, handsets, setup, porting and inbound number charges as separate lines. Ask each for a network readiness assessment and their porting process in writing.
Frequently asked questions
How much does business VoIP cost per user in Australia?
In 2026, roughly $15 to $25 per user per month for entry level plans, $25 to $40 for standard business plans with unlimited local and national calls, $35 to $55 where unlimited calls to Australian mobiles are included, and $50 to $90 per agent for contact centre tiers. SIP trunking for an existing PBX runs about $10 to $25 per channel per month.
Is pay as you go or unlimited cheaper?
It depends entirely on your call profile, so do the arithmetic rather than guessing. Pay as you go carries a lower seat price plus roughly 8 to 12 cents per untimed local or national call and 15 to 25 cents a minute to mobiles. Get three months of itemised call data from your current provider and price it both ways. Many businesses land best on a mixed deployment with heavy callers on unlimited and everyone else on pay as you go.
Should I buy or rent handsets?
Buying is usually better value. Handsets cost $120 to $400 each to purchase against $8 to $20 per month to rent, so rental typically overtakes purchase within about two years and leaves you owning nothing. Also check whether rented handsets are locked to the provider, since that is a switching cost disguised as convenience. Many roles need no desk phone at all, since a softphone and a good USB headset do the same job.
How long does number porting take?
A simple port of a single number typically takes five to fifteen business days. Complex ports involving multiple numbers, number blocks or numbers bundled with other products take considerably longer and are more prone to rejection over mismatched account details. Never cancel your existing service before the port completes, because cancelling releases the number and it may be unrecoverable.
What internet connection do I need for VoIP?
Voice uses only about 100 kilobits per second per concurrent call, so raw speed matters far less than consistency. What you need is low jitter, low packet loss and stable latency, a business grade connection, a router that supports quality of service so voice is prioritised over file transfers and video, and enough upload capacity for your expected concurrent calls. Ask for a network readiness assessment before migrating.
What happens to my calls if the internet goes down?
With a properly configured hosted VoIP service, inbound calls fail over automatically to nominated mobiles or an alternative destination, because the call routing happens in the provider's cloud rather than on your premises. Confirm this failover is configured and tested rather than assuming it, since it is one of the genuine advantages of hosted VoIP over an on premise PBX and it is frequently left unconfigured.
