24/7 Smart Call Handling and Lead Automation 

An AI Voice Agent is a virtual receptionist powered by Artificial Intelligence that can answer calls automatically, communicate naturally with customers and perform routine tasks such as sharing travel package details or collecting lead information. 

Unlike traditional IVR systems, this AI agent understands natural language, detects customer intent and provides human-like, context-aware replies-all without human intervention. 

The agent ensures your business is always available, managing calls 24/7, including weekends and holidays, so that no lead or inquiry is ever missed. 

1. 24/7 Call Handling 

Your customers can reach you anytime, day or night. The AI agent answers calls instantly, ensuring zero missed opportunities and a constant brand presence. 

2. Automated Lead Capture 

Every inquiry-name, contact, destination interest, or travel date-is automatically captured and logged into Google Sheets using n8n automation.  No more manual data entry or lost leads. 

3. Improved Productivity 

By automating repetitive conversations, your staff can focus on closing sales, planning itineraries and providing premium service rather than managing basic inquiries. 

4. Smarter, Natural Conversations 

The AI understands questions, provides personalized answers and adapts to customer intent using advanced language models-making conversations sound genuine and human-like. 

5. Enhanced Customer Experience 

Instant responses, polite interactions and consistent availability lead to better engagement, higher trust and improved satisfaction among your customers. 

Here are some ways travel businesses are using AI voice automation effectively: 

• Travel Agencies: Handling flight and hotel inquiries automatically. 
• Corporate Travel Desks: Managing employee travel requests and approvals. 
• Tour Operators: Guiding customers through package bookings and itineraries. 
• Airline Partners: Offering instant ticket updates and flight status via call. 

Each use case connects through n8n automation, reducing human workload by over 60% and improving response time by 3x. 

Our system is built on a modular, no-code automation platform - n8n, which enables seamless integration between your AI voice agent and other tools.

1. Call arrives - Customer dials your business VoIP number.
2. Connect to Voice Agent - SIP/VoIP provider routes call to the voice agent runtime.
3. Greet & Ask Intent - Agent greets caller and asks one question to identify intent (flight/hotel/package).
4. Capture speech → STT - Real-time speech is transcribed to text.
5. Intent + Slot Extraction (LLM) - LLM extracts required fields: Name, Phone, Email, Destination, Dates, Budget.
6. Confirm & Clarify - Agent confirms captured values and asks only for any missing required slots.
7. Send to n8n (webhook) - Agent posts structured JSON (lead, transcript, recording link, confidence) to n8n.
8. n8n actions - Validate/normalize data → append to Google Sheets and/or create/update CRM lead → store recording/transcript to cloud storage.
9. Notify & Schedule - n8n triggers notifications (Slack/Email/SMS) to assigned sales rep and creates follow-up task if needed.
10. Escalation & Logging - Low-confidence or “speak to human” requests create escalation tickets; all events logged for analytics.

Each step is automated and tracked in real-time to ensure smooth operation, accurate data collection and prompt follow-up by your team.

Our system uses cutting-edge AI technologies to make the experience natural, interactive and intelligent:

• Speech-to-Text (STT): Converts customer speech into text with high accuracy.
• Large Language Model (LLM): Understands intent, context and provides human-like responses.
• Text-to-Speech (TTS): Replies in natural, clear and multilingual voices for better communication.
• Agentic AI Logic: Handles dynamic question-answer flows, escalations and smart decision-making during calls.

Together, these models create a virtual assistant that can think, understand and respond like a real human travel agent.
