- Proven at contact-center call volume

Solves the hard parts of phone agents — telephony, low-latency turn-taking and barge-in — while leaving STT/LLM/TTS fully pluggable.
- Telephony and interrupts handled
- Pluggable STT + LLM + TTS stack
- Fast to a working phone agent
- Generous developer free tier
- Per-minute costs stack across layers
