Quick Navigation

AI Call Transcription & Summary

Real-time transcription. Instant summaries. Smarter conversations.

Built directly into the PBX, this new AI feature enhances call management by converting spoken conversations into text—live and after the call.

Features:

  • Live Transcription: See real-time text as the conversation unfolds—perfect for video or voice calls.
  • Auto Summary: Instantly receive a concise, structured summary of each call, including key takeaways and action items.
  • Speaker Identification: Follow who said what, line by line, for clearer understanding.
  • Searchable Logs: Easily review past conversations from your call history.

📌 Available on Software Edition & Cloud Edition.

Also Available in P-Series AI Suite:

  • Voicemail Transcription: Read voicemails instead of listening to them.
  • Text-to-Speech (TTS): Convert written messages into spoken dialogue to streamline caller interactions.

WebSocket for Audio Streams Transmission

Seamlessly connect your PBX to third-party AI systems and analytics tools.

The latest update introduces WebSocket support for one-way audio stream transmission during live calls. This enables developers and integrators to:

  • Capture live call audio packets.
  • Access call metadata (call ID, channel, status).
  • Connect with third-party tools for real-time transcription, speech analytics, or custom AI processing.

📌 Available on Software Edition & Cloud Edition.

Virtual Fax

Modern faxing—no machines, no noise, no paper.

Fax is still essential in many industries, but the old way is outdated. Now with Virtual Fax in Yeastar P-Series, faxing is fully digital and integrated into your PBX workflow.

Capabilities include:

  • Send faxes directly from Linkus Web or Desktop Client.
  • Receive faxes via PBX (with optional email forwarding).
  • Customize fax cover pages at the extension or admin level.
  • Access and monitor fax logs anytime.

Say goodbye to fax machines and hello to simpler, more efficient document handling.

Additional Optimizations

Emergency Number Trunk Assignment

Assign specific trunks to emergency numbers per extension—for faster, more reliable emergency call routing.

Role Menu Permissions

Admins can now manage role-based permissions beyond the Super Admin role, improving control over branch PBX environments.

New Function Key – Set Presence

Quickly update your user presence (e.g., Available, Away, DND) directly via function keys for better team visibility and call routing.
