On 15 April 2026 Yeastar made P-Series V23.3 generally available for the Cloud Edition (firmware 84.22.0.138, followed on 21 April by 84.22.0.139 with a call-report fix). The headline is the AI Receptionist: a virtual agent that lives inside the PBX and picks up calls. Yeastar announced it the same day. Here is what it does, how it is paid for and what to check, based on Yeastar's release notes and Yeastar's own announcements.
What the Yeastar AI Receptionist does
The release notes describe it as a 24/7 virtual assistant that answers calls automatically. In practice that means four jobs:
- Answer and greet every call, at any hour, with your company's greeting.
- Answer questions from a knowledge base you give it — Yeastar's launch release mentions your own documents and websites.
- Route the call based on what the caller wants — their intent — instead of which key they pressed.
- Report on what happened: a new "AI Receptionist Call Activity" report sits under the AI reports, and calls show up in the call records.
In the PBX, the AI Receptionist becomes a destination like any other. You can point an inbound route or an IVR option at it. Yeastar's launch release cites 34 languages, a choice of voices and no-code setup with templates.
Where it helps — and where it doesn't
An AI receptionist is good at the calls that repeat: opening hours, directions, "is my order ready", "I'd like to speak to sales". It frees people from those and catches calls after hours that would otherwise go to voicemail.
It is only as good as the knowledge base behind it. Out of date answers in, out of date answers out. Keep a clear path to a human for anything sensitive or unusual, and listen to some calls in the first weeks.
How AI Receptionist minutes work
The AI Receptionist is metered by the minute. According to the release notes:
| Option | What you get |
|---|---|
| Included | 60 one-time free minutes per PBX |
| One-Time Capacity | A block of minutes; buy more when it runs out |
| Monthly Quota Pack | 200 minutes a month; you can take several; unused minutes don't roll over |
If you have both, the monthly pack is used first. Notifications warn you as usage nears the limit and when it's reached. Add-on minutes are bought through a Yeastar partner or your service provider.
Which plan does it need?
The release notes don't name a plan for the AI Receptionist. Yeastar's V23.3 beta blog post, however, says an active Enterprise Plan or Ultimate Plan is required to activate and manage it. The minutes beyond the free 60 are a paid Yeastar add-on either way.
Our Yeastar P-Series Cloud PBXs run on the Enterprise Plan. Because the minutes are an add-on, ask our support whether it's available for your PBX before you plan around it.
Other changes in V23.3
V23.3 is a big release beyond the AI Receptionist:
- AI Transcription add-ons: a one-time block or a 500-minute monthly pack. The notes list 120 free transcription minutes on the Enterprise Plan and 240 on the Ultimate Plan. The built-in AI features move to an "AI Toolbox" page.
- Custom call reports: build your own reports from datasets, metrics, dimensions and filters under "My Reports", with access by role.
- Linkus multi-client login: limit how many Linkus apps can sign in to one extension, and see or sign out each device remotely.
- Microsoft Entra ID: avatar sync, and Outlook contact sync now only needs settings on the PBX side.
- More business hours: up to 20 custom time periods instead of 10.
A security update you shouldn't skip
The 84.22.0.138 GA build also shipped what Yeastar called robust security updates, with a strong recommendation to upgrade. Even if you never use the AI Receptionist, V23.3 is a release to have.
What this means for you
On a Yeastar P-Series Cloud PBX from PBXfactory, Yeastar's updates are applied for you in announced maintenance windows, and urgent security fixes sooner.
Setting up an AI Receptionist — the greeting, the knowledge base, the routing — is PBX configuration. Yeastar's documentation walks through it, and our support packages are there if you want a hand. Whether you can use it, and how extra minutes are billed, is a question for our support team before you build your call flow around it.
