Retell AI Reliability Patterns

Overview

Implementation patterns for Retell AI reliability patterns — voice agent and telephony platform.

Prerequisites

• Completed retellai-install-auth setup

Instructions

Step 1: SDK Pattern

import Retell from 'retell-sdk';
const retell = new Retell({ apiKey: process.env.RETELL_API_KEY! });

const agents = await retell.agent.list();
console.log(`Agents: ${agents.length}`);

Output

• Retell AI integration for reliability patterns

Error Handling

Examples

Design a safe fallback for a dependent CRM outage

Give the voice flow a short, explicit timeout for CRM lookup and a fallback response that either schedules a follow-up or transfers to a human queue. Test the fallback by making the preview CRM endpoint return a controlled error, then confirm no call is retried or double-booked. Track the fallback rate separately from general call failures and remove the temporary routing change only after the dependency and a synthetic recovery call both succeed.
