Bandwidth real-time call transcription

[lukeocodes]

Server-side Node.js using the Bandwidth Node SDK (@bandwidth/sdk). Bandwidth is a US carrier-grade CPaaS used by enterprises. Uses the Voice API to answer inbound calls and stream audio via Bandwidth's media streaming (WebSocket BXML verb) to a Node.js server, which forwards to Deepgram live WebSocket.

Professional path: Bandwidth BXML (stream verb) → WebSocket server → Deepgram STT

Thanks for the suggestion! 🎉

I've queued this for the team. The Engineer will research Bandwidth's WebSocket media streaming (BXML <StreamUrl> verb) and build a Node.js example that forwards live call audio to Deepgram STT.

I'll update this issue when a PR is ready. If you have more context — like specific Bandwidth SDK versions you're using, or whether you need real-time interim results vs. final transcripts — feel free to add it here. It helps the build go faster.
