Chat Transport & SMS Integration

  1. Twilio SMS Transport: Send chat responses directly via SMS using TwilioSMSChatTransport in CreateChatDTO.transport. This enables programmatic SMS conversations with your voice assistants, bridging the gap between voice and text communication.

  2. SMS Session Management: Create new sessions automatically when using SMS transport by providing:

    • customer: Customer information for SMS delivery
    • phoneNumberId: SMS-enabled phone number from your organization
    • Automatic session creation when both fields are provided

  3. LLM-Generated vs Direct SMS: Control message processing with TwilioSMSChatTransport.useLLMGeneratedMessageForOutbound:

    • true (default): Input processed by assistant for intelligent responses
    • false: Direct message forwarding without LLM processing for notifications and alerts

  4. Enhanced Chat Creation: CreateChatDTO now supports sophisticated session management:

    • transport: SMS delivery configuration
    • sessionId: Use existing session data
    • Mutual exclusivity between sessionId and transport fields for clear session boundaries

  5. OpenAI Responses Integration: Streamlined chat processing with OpenAIResponsesRequest supporting the same transport and squad integration features for consistent API experience.

  6. Cross-Platform Continuity: Seamlessly transition between voice calls and SMS conversations within the same session, maintaining context and conversation history across communication channels.

SMS transport requires SMS-enabled phone numbers in your organization. The phone number must support SMS functionality and belong to your account for successful message delivery.
