Choosing how to answer your phone.
In Australia you’ve got three real options for never missing a call: a usage-based AI receptionist like InStack, a flat-fee AI receptionist, or a human answering service. Here’s an honest look at how they differ — including where another option might suit you better.
Side by side, no spin.
Four things worth knowing.
You only pay for calls it handles
No monthly fee. A booking call costs about a dollar — you pay for the call you just watched happen, and nothing when the phone is quiet.
It books, it doesn’t just answer
InStack checks your live calendar for real availability, books the slot, and texts the client a confirmation — not just a message left for you to chase later.
It’s Australian and your data stays here
Hosted in Sydney, encrypted, and kept onshore. Read our Trust & Compliance page for exactly where your call data lives.
Try it yourself in minutes
No sales call to get started. Set it up self-serve and ring the live demo line to hear exactly how it sounds before you commit.
When another option might suit you better.
We’d rather you pick the right thing than the InStack thing. A few cases where someone else is the better call:
You want a human on every call
If a real person picking up matters more than anything else, a human answering service is the honest fit — warmth and judgement on every ring.
→ Human answering serviceYou prefer one fixed monthly bill
If predictable budgeting beats paying per call — even in quiet months — a flat-fee AI receptionist may suit the way you like to plan.
→ Flat-fee AI receptionistYou’re a large clinic, deep in one system
If you live inside a single practice-management platform, a clinic-specific tool already integrated there may plug in faster than anything new today.
→ Embedded practice toolDon’t take our word for it. Ring the agent.
Call the demo line and ask the agent to book you in. Listen to how it checks the calendar, confirms the time, and texts you back — then decide.
