Agents Platform

  • Real-time conversation monitoring: Enterprise users can now monitor agent conversations in real-time via WebSocket connection at /v1/convai/conversations/{id}/monitor. Features include cached conversation history, selective event streaming, and control commands (end call, barge-in, human takeover toggle, send messages).
  • Hinglish language support: Added hinglish_mode configuration option for agents. When enabled and the agent’s language is Hindi, responses will be in Hinglish (Hindi-English mix).
  • Dynamic variables in voicemail messages: Voicemail detection messages now support dynamic variable substitution, enabling personalized messages when voicemail is detected.
  • Localized widget terms and conditions: Chat widget terms and conditions can now be localized per language, configured through language presets.
