What it is
Rasa is a long-running open-source conversational AI framework with NLU, dialog policies, and now LLM-powered CALM stories. Voice deployments wrap Rasa with Twilio Media Streams, Genesys, or Audiocodes connectors plus an ASR/TTS pair. Rasa is the default choice when buyers need self-hosted control and a transparent training pipeline.
Watch out for: Voice channel typically requires custom telephony adapters or third-party connectors.
