Is it right for you?

  • Does it provide Australian geographic numbers (02, 03, 07, 08 area codes) or just 1300/1800 numbers?
  • Is the support team based in Australia and available during Australian business hours?
  • Is pricing in AUD, or will you pay USD with currency conversion on each invoice?
  • Does it meet the Australian Communications and Media Authority (ACMA) number portability requirements?
  • Can you port your existing Australian business number to the new provider?

Quick verdict

For Australian small businesses wanting a simple, locally supported solution: MyNetFone and Vonex are the most common choices, with Australian support teams and AUD pricing. For businesses that need integration with Microsoft Teams or Salesforce: 8x8 and RingCentral have AU data centers and reasonable local support. Avoid US-only providers that technically accept AU customers but cannot reliably provision local geographic numbers.

Quick answer

Summary: The Australian VoIP market has a significant split: providers with strong long-term reputations versus how those reputations hold up after acquisitions. MyNetFone, once one of Australia's most trusted VoIP providers, was acquired by Vonex in August 2021. ProductReview.com.au shows MyNetFone at 1.7/5 from 542 reviews, with virtually all the 1-star reviews citing the Vonex transition. Vonex's own newer customer base rates it 4.9/5. For AU small business: Vonex Hosted PBX or 8x8 for local support and AUD pricing. For businesses needing Microsoft Teams or Salesforce integration: 8x8 and RingCentral have AU data centers. Avoid signing with any AU provider without checking their current ProductReview score first. [ProductReview.com.au, 2024-2025]

Australian phone system considerations that differ from the US

Geographic numbers (02 Sydney/NSW, 03 Melbourne/VIC/TAS, 07 QLD, 08 WA/SA/NT) identify where a business is located to Australian customers. A Sydney business with a 03 Melbourne number raises questions. Make sure your provider can provision the correct geographic number for your state.

1300 numbers are shared-cost numbers (callers pay local rates; the business pays for calls from mobiles and interstate). 1800 numbers are toll-free. Many businesses use 1300 or 1800 for national branding alongside a local geographic number.

Contract terms in Australia lean more month-to-month than the US market. Most local providers offer no-lock-in plans at a small premium over 12-month contracts. This is worth insisting on before you know how a provider performs long-term.

MyNetFone: strong history, troubled since Vonex acquisition

MyNetFone built a strong reputation over two decades as one of Australia's most reliable VoIP providers. Then Vonex acquired the residential and SMB division in August 2021, and ProductReview.com.au tells the rest of the story: 1.7 out of 5 stars from 542 reviews, with an 84% negative rate.

The pattern in the reviews is consistent. Long-term customers (5, 10, even 20 years with MyNetFone) describe a cliff after the Vonex transition: calls stopped transmitting, PBX platform migration caused constant dropouts, hold times for support ran 1+ hours, and billing issues went unresolved for months. One NSW IT consultant tried four times to contact support and waited 40 to 60 minutes each time: "I DO NOT RECOMMEND THIS BUSINESS." A QLD customer reported overcharging for 18 months after requesting cancellation, calling the company "immoral." [ProductReview.com.au, MyNetFone, 2021-2025]

The key takeaway: MyNetFone as a brand still exists and is now operated by Vonex. Whether the service quality has improved since the transition period depends on when you are reading this. Check the ProductReview page for recent reviews before signing.

Vonex: strong for new customers, patchy product execution

Vonex's own brand (separate from the MyNetFone migration customers) rates 4.9 out of 5 from 300 ProductReview reviews, which looks impressive. The reviews name specific support staff by name and focus heavily on customer service interactions rather than product performance.

The negative reviews reveal real product issues. One business owner reported a 50% price increase mid-contract. Another signed up specifically for the ability to use the Vonex app overseas, only to discover after three months that Vonex had changed the service to require a VPN for overseas access. A separate reviewer reported the softphone app being discontinued without notice. [ProductReview.com.au, Vonex, 2023-2025]

Vonex Hosted PBX starts around AUD $20/user/month and includes geographic numbers, call recording, voicemail to email, and basic IVR. The mobile app quality gets positive mentions from current customers who did not migrate from MyNetFone.

8x8 and RingCentral for Australian businesses

Both 8x8 and RingCentral have Australian data centers and support Microsoft Teams and Salesforce integrations, which matter for businesses that need enterprise-grade software connections. Their Australian pricing runs roughly AUD $30 to $50/user/month.

8x8 has a stronger reputation in Australia for compliance-sensitive industries (professional services, financial services) because of its call recording and retention features. RingCentral fits businesses already using RingCentral elsewhere who want a consistent global platform.

For a pure Australian small business without global operations or enterprise integrations, 8x8 and RingCentral cost more than local alternatives without meaningful feature advantages for straightforward call handling.

Frequently asked questions

Can I keep my existing Australian business phone number if I switch to VoIP? Yes. ACMA regulates number porting in Australia and all licensed carriers must allow it. The process typically takes 3 to 10 business days. Get a written porting commitment and timeline from your new provider before canceling service with your existing carrier, and do not cancel your current service until the port completes.

Is VoIP call quality reliable enough for Australian business use? In metro areas with NBN, VoIP call quality is generally comparable to traditional phone lines. In regional areas with lower broadband speeds or higher latency, quality can suffer. The minimum is typically 100 kbps per simultaneous call with consistent latency under 150ms. Test your connection quality before committing.

Do Australian VoIP plans include calls to Australian mobiles? This varies. "Unlimited local and national calls" often means geographic landlines only. Calls to 04xx mobile numbers frequently cost AUD $0.09 to $0.22/minute as a separate charge. If a significant portion of your calls go to mobiles, verify explicitly whether mobile calls are included before you sign.

What happened to MyNetFone customers when Vonex took over? Vonex acquired MyNetFone's residential and SMB customers in August 2021. Many long-term MyNetFone customers reported service deterioration, call quality issues, PBX platform migration problems, and difficulty reaching support after the transition. These are reflected in the 1.7/5 ProductReview score on the MyNetFone listing [ProductReview.com.au, 2024-2025]. The Vonex-branded product has a separate and more positive recent review history.

What to do next

Most of the tools mentioned offer free trials. We recommend running 2–3 in parallel with real support tickets before committing — demos show the best case, trials show the real experience. Check integration compatibility with your CRM and ecommerce platform before starting a trial.
