Founding pilot — limited spots

An AI receptionist on Yeastar — the PBX we chose for ourselves.

Native Australian voices, MCP support for real AI integrations, and your existing number. Deployed by an Australian MSP that is migrating its own phone system from 3CX to Yeastar as this page is written.

In short: yes — an AI receptionist can run on your Yeastar system, two ways. Yeastar's own built-in AI ships Australian voices (two male, two female at the time of writing) and the P-Series now exposes MCP, so AI agents can act on the phone system itself. Where the native features end, a custom stack joins the PBX as a SIP destination on your existing number. AI4SMB configures, tunes and monitors either — run by an MSP founder 32 years into phone systems, currently migrating his own company to Yeastar.

Why Yeastar

The first PBX where the AI story is native.

Native Australian voices — two male, two female

Yeastar’s built-in AI ships AU voices at the time of writing. That flips the usual trade-off: on most systems, sounding Australian requires a custom voice stack. On Yeastar the accent is table stakes — so the work moves to what the AI actually does with the call.

A PBX that speaks MCP

Yeastar has begun exposing MCP, the protocol that lets AI agents use software as tools. A phone system AI can act on — look up callers, transfer, log — is a different category from one AI can merely bolt onto. Wiring agents into business systems is our home ground.

We are migrating to it ourselves

This is not a vendor page. PearceIT — our founder’s MSP — is moving its own operation from 3CX to Yeastar right now. The advice here is the advice we gave ourselves, and we get to live with the consequences.

Run like infrastructure

Monitoring, transcripts, hand-off rules, backups and support — the same operational discipline as the rest of your phone system, because for us it is part of your phone system.

Honest framing

If the native AI does the job, we'll tell you — and just set it up well.

On 3CX, the native AI's gap is the voice — no Australian accent — and a custom stack closes it. On Yeastar the voices are already Australian, so the honest question changes: what do you need beyond them? For some businesses, nothing — native answering, configured properly, is the right call, and saying so costs us a sale. The gap that remains is depth: call-flow design that matches how your business actually runs, knowledge of your services and pricing, explicit escalation rules, monitoring in production — and, with MCP, an AI that can act (book the job, log the caller, check the calendar) rather than just answer. That integration layer is what the founding pilot is proving. The audit tells you which side of the line your business sits on, honestly.

Yeastar + AI receptionist, straight answers

Can an AI receptionist work with my existing Yeastar system?
Yes. On Yeastar there are two honest routes: the P-Series’ own built-in AI features, which have been landing at a rapid clip, or a custom AI stack joining the PBX as a SIP destination — reached through your existing call flow, ring groups and after-hours rules, on the number you already advertise. Which route fits depends on what you need the AI to actually do, and the audit tells you that before anything is deployed.
Does Yeastar’s built-in AI have an Australian accent?
Yes — and this is the headline difference from most of the market. At the time of writing, Yeastar’s native AI ships Australian voices: two male and two female. Compare 3CX, whose native AI runs on OpenAI’s realtime voice set with no Australian accent available. If AU-sounding calls matter to your business and you are choosing a phone system anyway, this single fact should be in your decision — and most vendors selling you an AI receptionist will not mention it.
What does MCP support in a PBX actually mean?
MCP (Model Context Protocol) is the emerging standard that lets AI systems safely use other software as tools. A PBX that exposes an MCP server — which Yeastar has begun doing; at the time of writing it is in beta, with custom MCP servers, per-agent tool permissions and logged invocations — means an AI agent can act on the phone system itself: look up a caller, place or transfer a call, read presence, log an interaction. In practice it is the difference between an AI receptionist that can only talk and one that can do. Because it is beta, we verify it against your actual use case before we quote against it — that is part of what the audit is for. This is new ground, and it is exactly the kind of integration work we exist for.
We run 3CX today — is moving to Yeastar worth it?
We are the right people to ask, because we are doing precisely that: our founder’s MSP is migrating its own operation from 3CX to Yeastar as this page is written (August 2026). The honest answer is that it depends — 3CX remains a capable system and we still deploy and support it. Our reasons were Yeastar’s native Australian voices, its MCP support, and a release cadence on AI features that, in our observation deploying both, has been markedly quicker. An audit maps whether those reasons apply to your business or not.
Do I need a particular Yeastar model or plan?
The AI-era features live in the P-Series line (cloud or appliance). During the audit we check your series, firmware and plan against what you want the AI to do — native features, custom stack, or both — and tell you straight if anything needs attention first. We run Yeastar ourselves, so this check is quick and current.
What does an AI receptionist on Yeastar cost?
In layers, honestly. If you need the PBX itself hosted, a hosted Yeastar system starts from $150/month ex GST. Yeastar’s native AI features come with P-Series licensing — if they cover your needs, the answer may be “very little on top”, and we will say so, then simply configure them well. The custom stack is founding-pilot pricing, set per business by call volume and integration depth. Every engagement starts with the audit — analysis and a written report, from $800 ex GST — which gives you exact numbers for your setup. Our cost breakdown explains what drives the price, and an audit call starts it.

Run Yeastar — or thinking about it? We're mid-migration ourselves.
