Sinch voice call transcription

[lukeocodes]

Server-side Node.js using the Sinch SDK (@sinch/sdk-core). Handles inbound PSTN/SIP calls via the Sinch Voice API, streams audio via the SVAML conference bridge or WebSocket audio hook, and forwards to Deepgram live WebSocket. Sinch has significant market share in enterprise voice APIs.

Professional path: Sinch Voice API (callout / conference) → audio tap → Deepgram STT

Credentials likely needed

• SINCH_APPLICATION_KEY
• SINCH_APPLICATION_SECRET
• SINCH_PHONE_NUMBER
• DEEPGRAM_API_KEY

Language

Thanks for the suggestion! 🎉

I've queued this for the team. The Engineer will build a Sinch Voice API + Deepgram STT example in Node.js — handling inbound calls via the Sinch SDK, tapping the audio stream, and forwarding it to Deepgram for real-time transcription.

I'll update this issue and close it when the example is released.

Tracking: #157

If you have more context (specific Sinch call flow you prefer, audio format details, or credentials you have access to), feel free to add it here — it helps the build go faster.
