Voxtra

Open voice infrastructure for AI agents. A Python framework that bridges telephony infrastructure (Asterisk, FreeSWITCH, LiveKit) with AI voice agents — letting developers build AI-powered call centers without needing to understand telecom internals.

Architecture

Code-First

Build voice AI agents with a clean decorator-based API. Route calls, handle sessions, and integrate AI — all in Python.

from voxtra import VoxtraApp
app = VoxtraApp()
@app.route(extension="1000")
async def support(session):
await session.say("Hello!")

Config-First

Define your entire voice AI pipeline in YAML. No code needed for simple agents — just configure and run.

app_name: my-call-center
telephony:
provider: asterisk
ai:
stt: deepgram
llm: openai
tts: elevenlabs

Supported Providers

Pluggable architecture with support for multiple telephony, STT, LLM, and TTS providers.
