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.

  • 🚦 New Function Key: Set Presence – update call status quickly for better handling.
