What it is
Agent Voice Response is a self-hosted system that turns an Asterisk PBX into a real-time voice AI agent. Callers can interrupt while it speaks through voice-activity detection. Its composable microservices let operators swap automatic speech recognition, language-model, and text-to-speech engines. It supports Asterisk AudioSocket on Asterisk 18 and later, including named systems such as FreePBX, VitalPBX, Vicidial, Elastix, and custom dialplans. Listed integrations include OpenAI, Anthropic, Deepgram, ElevenLabs, Google, Ollama, Vosk, Kokoro, Ultravox, OpenRouter, CoquiTTS, and Silero. Noise cancellation and echo suppression are described before audio reaches the model. Local deployments can use Vosk or Silero, Ollama, and CoquiTTS or Kokoro, keeping caller audio on the network according to the maker. Docker microservices can scale horizontally behind a load balancer. AVR is free for personal and commercial use, with no license keys or per-minute charge. Setup requires Docker images, provider configuration, and an Asterisk dialplan extension.

Strong points and limits
Strong points
- Interruptible conversations through voice activity detection
- Hot-swappable ASR, LLM, and TTS engines
- Local deployment options for recognition, reasoning, and speech
- Free for personal and commercial use
- Horizontal scaling with stateless Docker microservices
Limits
- Self-hosted setup requires Docker and dialplan configuration
- Requires Asterisk 18 or later for AudioSocket
- Call recording is not supported
Who it suits
It suits teams running Asterisk-based telephony that want configurable voice AI, including customer support, contact centers, healthcare assistants, voice commerce, learning, or IoT control. Self-hosted deployments can suit organizations that want caller audio kept on their network.
Verdict
Agent Voice Response provides a configurable, self-hosted voice agent around Asterisk, with many named AI providers and local components. Its free licensing and local-processing options are useful, but deployment requires telephony and Docker setup, and there is no call recording.
