Legacy IVR systems are one of the biggest causes of call abandonment in insurance and banking. In this guide, we explore how AI-powered voicebots using Amazon Connect and GenAI are transforming contact centers.
It's 9:14 PM. You've just been in a car accident. You call your insurance company — hands shaking, car still steaming — and you hear it:
"Press 1 for auto insurance. Press 2 for home insurance. Press 3 for life insurance. Press 4 for billing. Press 5 for claims. To repeat these options, press 9."
— "Every legacy IVR system, every insurance company, since 1998"
You press 5. Then wait. Then get transferred. Then wait again. Forty-three minutes later, you've spoken to three agents and still haven't filed the claim. You've also decided, quietly, that you're switching insurers.
This isn't a UX problem. It's a technology debt problem — and it has a real, deployable solution that's available right now, in 2026. I've spent the last 12 years building these solutions at scale, most recently migrating a major insurance carrier's legacy Avaya IVR to Amazon Connect. Here's everything I know.
The Real Problem: Legacy IVR Was Built for Phones, Not People
The Interactive Voice Response systems most banks and insurers run today were designed in the early 2000s — or even the late 1990s. They were built on on-premise hardware (Avaya, Genesys, Cisco) with a simple premise: route calls based on keypad input, reduce agent load, cut costs.
It worked, for a while. But caller expectations have changed dramatically. People now talk to Alexa, Siri, and ChatGPT. They expect to say "I want to file a claim for my Toyota Corolla that was hit in a parking lot this morning" — and have the system understand that, not force them to navigate a seven-level menu tree.

Real-World Scenario 1: Insurance Claims — The Midnight Accident
// Real-world scenario · Insurance · Claims filing Problem: A policyholder calls at 11 PM to file an auto claim
With legacy IVR: Caller navigates 4 menu levels → gets transferred to claims → waits 22 minutes on hold → agent manually looks up policy → asks 14 standard questions → schedules adjuster for 5 days later. Total time: 45 minutes. Customer satisfaction: low. Churn probability: high.
With AWS Connect + Lex + Lambda: Caller says "I had an accident." The voicebot identifies intent (FNOL — First Notice of Loss), authenticates via phone number match + last 4 of SSN, pulls policy details from the claims API, collects accident details through natural dialogue, pre-populates the claim in the system, and schedules a callback for the next morning — all in under 4 minutes. Agent receives a complete pre-filled case. No hold time.
This isn’t science fiction — it’s a production-grade system I’ve implemented for a large insurance provider. By combining Amazon Lex, AWS Lambda, and Amazon Polly within Amazon Connect, we built a fully automated claims intake flow that reduced handling time from minutes to seconds.
Real-World Scenario 2: Banking — The Balance Anxiety Call
// Real-world scenario · Banking · Account inquiry + fraud alert
Problem: Customer calls to check why a transaction was declined
With legacy IVR: "Press 1 for balance. Press 2 for recent transactions. Press 3 to report fraud." Customer doesn't know which option applies. Presses 2, hears the last 5 transactions read aloud by a robot voice, still doesn't understand why the transaction failed, presses 0 for agent. Wait time: 18 minutes.
With GenAI-powered chatbot (Amazon Lex + Bedrock): Customer says "My card was declined at the grocery store just now." Bot identifies this as a potential fraud block or limit breach, authenticates the customer, checks the transaction API in real time, sees the card was flagged for an unusual location (customer is travelling), explains this in plain English, and with one voice confirmation, removes the temporary block. Resolved in 90 seconds. Zero agent needed.
💡 Why GenAI changes the game here
Classic chatbots were rigid — they matched phrases to intents. If the customer said something unexpected, the bot failed. With Amazon Bedrock + Claude as the backbone, the bot can handle unexpected phrasings, explain complex banking policies in simple language, and maintain context across a multi-turn conversation — just like a human agent would.
The Technical Stack That Actually Works (In 2026)
After building and iterating on these systems across insurance and banking, here is the stack I recommend for any mid-to-large financial services contact center:
Layer 1 — Telephony & Routing
Amazon Connect is the clear winner here. It replaced our Avaya PBX entirely. It handles call routing, queuing, agent desktop, recording, and analytics — all in one cloud-native platform. Setup that used to take 6 months of on-prem configuration now takes 2–3 weeks in Connect's visual flow builder.
Layer 2 — Natural Language Understanding
Amazon Lex v2 for speech and text intent recognition. For high-stakes conversations (complex claims, financial advice), layer in Amazon Bedrock with a fine-tuned model. Lex handles the structured intents; Bedrock handles the open-ended questions.
// Example · Lex v2 intent for insurance FNOL
{
"name": "FileClaim",
"description": "First Notice of Loss — auto accident",
"sampleUtterances": [
"I had an accident",
"I want to file a claim",
"My car was hit",
"I was in a crash",
"Someone hit my vehicle"
],
"slots": [
{ "name": "AccidentDate", "slotType": "AMAZON.Date" },
{ "name": "AccidentLocation", "slotType": "AMAZON.City" },
{ "name": "VehicleType", "slotType": "AMAZON.Vehicle" },
{ "name": "PolicyNumber", "slotType": "PolicyNumberType" }
],
"fulfillmentCodeHook": {
"lambdaArn": "arn:aws:lambda:us-east-1:XXXX:function:FNOLHandler"
}
}
Layer 3 — Business Logic & Integrations
AWS Lambda functions connect Lex to your core systems — policy management APIs, claims databases, CRM, payment processors. Each Lambda is stateless, event-driven, and scales automatically. We used Lambda to pull real-time policy data, push claim records, send SMS confirmations via SNS, and trigger email workflows.
Layer 4 — Analytics & Continuous Improvement
This is where most projects fail — they deploy and forget. Use Amazon CloudWatch for infrastructure metrics, Contact Lens for call transcription and sentiment analysis, and build a weekly review loop where you examine the top 20 failed intents and retrain. This is how we got from 40% containment to 65% in 6 months.
The Migration Playbook: Legacy IVR → Amazon Connect
Based on a real-world migration from legacy platforms like Avaya to Amazon Connect, here’s the phased approach I recommend:
Audit & Map (Weeks 1–3) : Document every call flow in your existing IVR. Record actual call audio. Identify the top 20 call reasons — these are your first automation targets. In most insurance companies, 4 intents cover 60% of call volume: policy inquiry, billing, claims FNOL, and agent lookup.
Build the MVP on Connect (Weeks 4–8) : Set up Amazon Connect in your AWS account. Build the top 3 flows using the visual contact flow editor. Integrate Lex for the voicebot layer. Use Lambda to connect to one or two core APIs. Run in parallel with your legacy IVR — no cutover yet.
Shadow Traffic Testing (Weeks 9–11) : Route 5–10% of real calls to the new system while keeping agents on standby. Use Contact Lens transcripts to find edge cases. Retrain Lex intents based on actual customer language — this step doubled our intent accuracy.
Gradual Cutover (Weeks 12–16) : Ramp from 10% → 25% → 50% → 100% over 4 weeks. Have rollback ready at each step. Monitor containment rate, CSAT scores, and escalation rates daily. We achieved 20% CSAT improvement by week 14.
Decommission & Optimize (Week 17+) : Once Connect handles 100% of traffic and is stable, begin decommissioning legacy hardware. Shift budget from CapEx (hardware maintenance) to OpEx (pay-per-minute Connect pricing). Continue weekly intent retraining cycles.
What About GenAI and LLMs — Are They Ready for Banking?
Yes — with guardrails. The mistake I see teams make is deploying a raw LLM directly into customer-facing flows without constraints. In regulated industries like banking and insurance, you need:
Deterministic guardrails — certain questions (balance, policy details, claims status) must always pull from authoritative APIs, never from the LLM's own generation. The LLM handles explanation and conversation; the database handles facts.
PII handling — ensure no sensitive data (SSNs, account numbers, medical information) is sent to external LLM APIs.
Audit trails — every LLM response that touches a customer interaction should be logged with the input prompt, model version, and output. This is non-negotiable for compliance.
GenAI in contact centers isn't about replacing agents. It's about making every agent interaction start at a higher quality baseline — because the bot has already understood the context, gathered the data, and resolved everything it could.
Where This Is Headed
Over the next few months, customer experience will shift from reactive support to proactive, agent-driven engagement.
Instead of waiting for you to reach out, AI systems will take the initiative. Think of an intelligent, autonomous workflow that monitors events in real time and acts instantly:
Your policy is nearing renewal — an AI voice agent reaches out, verifies your details, and completes the renewal in a single interaction.
A suspicious transaction occurs — within seconds, an AI agent calls to validate the activity and prevent fraud.
This isn’t just automation — it’s agentic AI in action, where systems can decide, initiate, and complete tasks independently, with minimal human intervention.
At the same time, we’re moving toward true omnichannel continuity. Conversations are no longer tied to a single channel:
Start a query on WhatsApp
Continue it over a phone call
Finish it via chat or app
…and every interaction carries full context forward.
Platforms like Amazon Connect are already enabling this through capabilities like Contact Lens, making it possible to maintain a unified customer memory across channels.
