Integration: Sinch Voice API
Origin
Requested in #142: "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."
What this should show
A Node.js server that uses the Sinch Voice SDK (@sinch/sdk-core) to handle inbound PSTN/SIP calls, tap the call audio via the SVAML conference bridge or WebSocket audio hook, and stream the raw audio to Deepgram's live STT WebSocket for real-time transcription. Should demonstrate the full pipeline: Sinch call setup → audio stream extraction → Deepgram STT → transcript output.
