With Agent Voice Response (AVR) you can integrate AI-driven, real-time voice conversations directly into your IVR system. Callers can talk to a bot that listens, understands, and responds live — no recordings required.
AVR is open source and integrates with popular ASR, LLM, and TTS providers such as Google Speech, ElevenLabs, Ultravox, and more. This gives you full flexibility to choose the stack that best fits your use case.
I see the original post is hidden. I am the one that documented the link @gcareri shared. I needed a quick and dirty spin to get FreePBX to work with calling an Ultravox agent. And the shared repo worked.
The post was automatically flagged as spam by the system because it contained multiple links to the same domain and @gcareri is a first time user here on the forums (but a speaker at AstriCon !) Howdy!
Hi Chris,
thank you for pointing that out and no worries about the auto-flag. I totally understand.
Also, thank you again for the great experience at AstriCon 2025, it was a real pleasure to participate and share ideas with the community!
