telephony-server

Telephony Server is a powerful bridge that connects telephony providers (Twilio, Vonage, Plivo, etc.) with real-time communication platforms (LiveKit, Jay.so, Pipecat, etc.). It enables seamless call routing, robust metrics collection, and observability features for enhanced telephony operations. Maintained by steinathan on GitHub, where it has earned 23 stars from the community.

It's actively developed around llm, vocode, jay, and is a solid reference for anyone building with these tools.
