In short: Australian AI receptionists differ on five things that matter — whether they join your existing phone system or make you forward calls to a new number, how they charge (per minute, per call, or flat), whether the voice sounds Australian, where your call data lives, and whether anyone operates the thing after go-live. Below is the local field compared on those five, using each vendor’s own published claims (checked 18 July 2026), including where we fit and where a competitor is honestly the better pick.
Disclosure up front: I’m the founder of AI4SMB, which sells one of the products in this comparison. Everything below about other vendors comes from their own public websites as at 18 July 2026 — no testing claims, no secondhand reviews — and I’ll tell you plainly where someone else is the better fit. Vendor pages change; check current details before deciding.
The five questions that actually separate them
- Does it join your phone system, or replace it? Most products assign you a number and have you forward calls to it. That works, but it puts a second system between you and your callers. The alternative is wiring the AI into the PBX you already run as another destination — here’s the difference in detail.
- How does the pricing work? Per-minute, per-call, and flat-monthly models suit different call profiles. High volume punishes per-minute pricing; low volume makes flat fees expensive per call. Whatever the model, get your number in writing before committing — our cost guide covers what drives it.
- Does it sound local? Callers notice. Vendors differ from “100+ Australian voices” to no voice claims at all.
- Where does the call data live? Recordings and transcripts are personal information under the Privacy Act — and if you’re a clinic or dental practice, the APPs apply to you regardless of size. Ask specifically; here’s the legal picture.
- Who operates it after go-live? Software subscriptions leave the monitoring, tuning and transcript review to you. An agency model does it for you. Neither is wrong — but know which you’re buying.
The Australian field, on their own published claims
AiDial (aidial.com.au) publishes full pricing: plans from $199 to $499/month with a $1,500–2,000 setup fee, included minutes, and per-minute overage from $0.39–0.55, plus a $100/month compliance add-on. It claims “100+ Australian AI voices”, Australian data residency with facilities in Sydney, Melbourne and Canberra, and supports call forwarding, SIP routing, number porting or a new number. Named integrations include Cliniko, ServiceM8, HubSpot and Zapier. No lock-in contracts. On published detail — pricing, SLA page, compliance page — it’s the most transparent operator in the field.
Lyngo AI (lyngo.ai) is the clinic specialist: direct practice-management integration with Cliniko, Nookal and PracSuite that reads live availability and books, reschedules and cancels in real time. Per-call pricing from $139/month (45 calls) to $880/month (500 calls), unlimited minutes per call, free setup, no lock-in, 7-day trial. It claims compliance across GDPR, the APPs and other jurisdictions, and operates in six countries. If you run a Cliniko-based allied-health clinic and want self-serve booking automation, Lyngo is genuinely the obvious first look.
Johnni (johnni.ai) is trades-focused — it advertises training on “thousands of plumbing, electrical and building calls”, Australian accents, and deep trade-software integrations (ServiceM8, Simpro, ServiceTitan, Aroflo). The model is a local number you forward calls to. Pricing is a headline “$99 a month” with tiers and a request-a-quote path — confirm what the figure actually includes for your setup. 30-day free trial, no lock-in.
Sophiie AI (sophiie.ai) shows integrations with ServiceM8, Xero and calendar tools, and offers demos with no credit card. As at 18 July 2026 its site publishes no pricing and doesn’t state its integration mechanism — you’ll be getting those details in conversation with them, so bring the five questions above.
AI4SMB (that’s us) occupies the slot none of the above do: we integrate the AI into the PBX you already run — 3CX, Yeastar and other SIP systems — as another destination on your existing number, rather than a forwarding number. We’re the only one offering a self-hosted option for businesses whose call data can’t sit on someone else’s cloud, and we’re an agency, not a subscription: the receptionist is deployed and then operated like infrastructure — monitored, reviewed, supported. The honest other side: our Australian-voice stack is still being built and proven — that is exactly what the founding-pilot phase is — our pricing is quoted per business rather than published (so hold us to question 2 like everyone else), and if you just want cheap self-serve call answering with no operations layer, the vendors above will get you started faster.
The quick decision tree
- Cliniko clinic wanting self-serve booking automation → look at Lyngo first.
- Tradie on a mobile who wants a forwarding setup fast → Johnni or AiDial.
- Want published pricing and Australian data-residency claims → AiDial.
- Run a PBX (3CX/Yeastar), need your existing number, want privacy options and someone operating it → that’s us, and it’s exactly what the founding pilot is for.
- Not sure the economics stack up at all → do the maths first.
Whoever you pick: ask the five questions, get the answers in writing, and make them show you a real call on your own workflow before you sign. That advice costs every vendor on this page something — which is exactly why it’s good advice.
