  • Compliance checks for call recording and retention

Basic Flow (Successful Scenario)

  • Customer calls the support line or interacts with the voice assistant.
  • GPT interprets intent and retrieves data (support, booking, product info).
  • System responds in natural language and confirms resolution or booking.
  • If needed, escalation routes to a live agent with full transcript.
  • CRM logs the interaction and updates customer records.

Outcome: Customers get real-time, conversational support while businesses cut costs and improve satisfaction.

Imagine customers booking, troubleshooting, or shopping with just their voice - let’s pilot this automation today.

Alternate Flows

A1: Low confidence in recognition: System asks the customer to repeat or switch to keypad input.

A2: Backend API timeout: If booking or product system fails, call is queued for follow-up.

A3: Escalation request: If customer asks for a human, transcript is transferred to live agent.

A4: GPT error: If model fails to reply, fallback script provides generic guidance.
