I built 5 voice AI agents live on camera — and each one places a real phone call. Appointment booking, missed-call recovery, lead qualification, support triage, quote collection. No Python. No n8n. Just Claude Code + Telnyx.

Here's the problem: most people building voice AI agents in 2026 end up with a Frankenstack — 5 separate vendors stitched together (carrier, STT, LLM, TTS, glue layer). Latency drifts, calls drop, and debugging means jumping across 5 dashboards. Telnyx solves this with a single-stack architecture: telephony, LLM inference, STT and TTS co-located across 18 global network locations. One platform, one dashboard, zero Frankenstack.
