redialer.io is the callback layer for AI voice agents. Your agent handles the live conversation; redialer.io places the outbound follow-up call or SMS at the requested time — and retries when a call hits voicemail, no-answer, or busy. Webhook-driven, with per-agent quiet hours and retry rules. Built for Retell.
AI voice agents are great at the live conversation and terrible at the follow-up. When an agent says "I'll call you back at 3," or a call hits voicemail, no-answer, or busy, that callback usually falls through the cracks. redialer.io is the missing callback layer.
Your Retell agent handles the conversation; redialer.io handles the redial. It listens to Retell webhooks, detects how each call ended, and schedules the outbound follow-up call — or an SMS — at the requested time. If a call doesn't connect, your retry rules decide when and how often to try again, with sensible limits.
It's built for operators, not just demos: per-agent quiet hours and quiet days keep you inside acceptable calling windows, tier-gated retry delays prevent hammering a number, and outcome detection means you're only redialing the calls that actually need it. Everything runs off your existing webhook + n8n flow — there's no new API to integrate and no dialer to babysit.
Pricing is freemium: a free tier covers a single agent, and paid Starter, Pro, and Scale plans add multi-workspace and agency-volume capacity. It's purpose-built for Retell today, with Vapi and Bland support on the way.
If you run AI voice agents and lose revenue to missed callbacks, redialer.io closes that loop automatically.
