Voice AI is too important to be a black box. Your call data is sensitive — customer names, numbers, intents. With an open codebase:

Tel-Agent is released under **AGPL**, so improvements flow back to the community.

The pipeline is the classic voice-agent triangle, tuned for latency:

The hard part isn't any single step — it's keeping the round-trip under ~1 second so the caller never feels like they're talking to a robot on a delay. Interruption handling ("barge-in"), silence detection, and graceful fallbacks took more iteration than everything else combined.

The roadmap is public and moving: multi-language support (including Arabic — underserved in voice AI and personally important to me), deeper calendar integrations, and better analytics on call outcomes.

If you've ever wanted your business phone to just *handle it*, or you're curious how real-time voice agents are built — check out the repo, star it if you like the idea, open an issue, or just say hi in the discussions:
