Since July, Yeastar has been enhancing the P-Series PBX System with AI-powered features such as Voicemail Transcription and Text-to-Speech, giving businesses smarter tools to streamline communication and reduce costs.
Now, Yeastar is taking things a step further. The September 2025 update introduces AI Call Transcription & Summary, Virtual Fax, and WebSocket for Audio Streaming, all designed to make PBX smarter, more productive, and better connected.
Read on for a breakdown of the latest features and why they matter for your business.
AI Call Transcription & Summary
No more scrambling to take notes during calls. Yeastar’s AI Call Transcription & Summary feature:
-
📝 Transcribes calls in real time — follow along without missing a word.
-
🔍 Creates an instant recap — key points, action items, and decisions are automatically captured.
-
📂 Improves record-keeping — search and review past conversations directly in your call log.
This tool acts like your personal AI assistant, ensuring that every call turns into actionable insights — boosting focus, efficiency, and collaboration.
(Available on P-Series Software & Cloud Editions.)
WebSocket for Audio Streams Transmission
The P-Series PBX now supports one-way audio streaming via WebSocket, enabling deeper integration with external systems.
This means you can:
-
Stream real-time PBX audio data packets (call ID, channel ID, and more).
-
Connect directly with third-party transcription, speech analytics, or AI tools.
It’s a powerful feature for businesses looking to innovate with AI-driven call analysis and reporting.

Virtual Fax
Faxing is far from dead, but the old machines are. Yeastar’s new Virtual Fax modernises the process:
-
Send and receive faxes directly through the Linkus Web or Desktop Client.
-
Create personalised cover pages at the extension level.
-
Receive optional email copies of incoming faxes.
-
Check fax logs for real-time status tracking.
No more paper jams, noisy connections, or costly equipment — just a streamlined, digital faxing experience built right into your PBX.
Additional Optimisations
The update also includes:
-
📞 Emergency Number Trunk Assignment – assign trunks for faster, reliable emergency calls.
-
🔑 Expanded Role Menu Permissions – more flexibility for branch administrators.
