How integration works

Inbound agents

For inbound agents (your agent receives calls), SuperBryn:
  1. Places a phone call to your agent’s number via LiveKit
  2. The AI caller follows the scenario
  3. The call is recorded and transcribed via LiveKit’s infrastructure

Outbound agents

For outbound agents (your agent initiates calls), SuperBryn:
  1. Sends a trigger request to your agent’s configured URL with the payload metadata
  2. Your agent initiates a call to SuperBryn’s listening endpoint
  3. The AI caller answers and follows the scenario

Voice profiles

During simulation, SuperBryn selects TTS voices that match the scenario requirements:
  • Language and gender matching: Voices are matched to the agent’s configured language and gender
  • Provider-specific voices: Supports Cartesia and ElevenLabs voice profiles
  • Ring-specific behavior: Some rings use specific voice profiles (e.g., Ring 4 selects accented voices)
