Depot pick for shipping a phone/voice agent without assembling vendors. LiveKit when you want OSS + realtime media control; Deepgram when STT quality is the product and you will orchestrate yourself. Strengths: The actual 'don't stitch STT+LLM+TTS' product with BYOK; Phone/SMS channels + concurrency SKU that maps to call centers; Clear $0.05/min hosting math.
Lock-in risk: higher = more lock-in (worse). Overall already inverts this dimension.
