What is it?

Jigasi is a server-side application that connects SIP clients to Jitsi Meet conferences hosted by Jitsi Videobridge. It registers as a SIP client rather than acting as a SIP server, handling XMPP signaling, ICE, and DTLS/SRTP termination so that telephone participants can be dialed into a meeting or call into one.

Beyond telephony, Jigasi can act as a transcriber in a conference, sending participant audio to a speech-to-text service and returning results as subtitles or chat messages, with a complete transcript saved at the end. Supported backends include Google Cloud speech-to-text, Vosk, a custom Whisper service, and Oracle Cloud AI Speech, and translation can be handled by LibreTranslate, Microsoft Translator, or a configured service.

SIP and transcription are toggled independently through configuration properties, so an instance can run either function or both.

Key features

  • 01Registers as a SIP client so SIP phones and B2BUAs can join Jitsi Meet rooms.
  • 02Supports dial-out from the Jitsi Meet invite dialog and dial-in routed by a SIP header.
  • 03Provides near real-time transcription shown as subtitles or chat messages.
  • 04Integrates with Google Cloud, Vosk, Whisper, and Oracle Cloud AI Speech for speech recognition.
  • 05Translates transcripts through LibreTranslate or Microsoft Translator.
  • 06Saves final transcripts as plain text or JSON.

Use cases

  • Letting landline or mobile callers join an existing Jitsi Meet video conference.
  • Dialing out to telephone participants from within a Jitsi Meet meeting.
  • Adding live subtitles and a saved transcript to self-hosted Jitsi Meet conferences.
  • Providing multilingual subtitles by combining transcription with a translation service.

Things to know

  • Transcription and translation depend on external services such as Google Cloud, Oracle Cloud, or Microsoft Translator, which require their own credentials.
