RETELL · LIVE

Retell callbacks, automated.

Your Retell agent handles the call. When a caller asks to be called back — or your call drops to voicemail, no-answer, or busy — redialer.io schedules the redial. Three steps in the Retell dashboard. Live today.

WHY REDIALER.IO · for Retell

Your Retell agent handles the call. We handle the callback.

Retell is great at the call. Scheduling a reliable callback when your agent promises one — webhook ingestion, time-zone math, retry policy across providers, audit logs, quiet hours, consent-aware exemptions — is a separate system. We are that system.

Same encryption
Every PII field (phone numbers, dynamic variables, metadata, captured call payloads) is encrypted at rest with AES-256-GCM under a per-tenant key wrapped in HashiCorp Vault. Retell never sees plaintext from us; we never see plaintext after the first decrypt.
Same retry logic
Voicemail / no-answer / busy / technical-error / inactivity groups each with their own toggle + delay. Per-workspace tuning. Per-agent overrides on Pro and Scale. Quiet-hours shift retries forward; explicit caller requests are exempt under TCPA's consent carve-out.
Same dashboard
Dashboard, agents page, activity feed, audit log, REST API — all provider-agnostic. Switch between Retell and any other connected workspace from the topbar without losing context.
Same compliance posture
TCPA-friendly defaults (no automated calls 19:00–10:00 local). 24h soft-delete grace on workspace disconnects. 30-day data export window on cancellation. Audit log on every mutation.
HOW IT WIRES · Retell side

What you do in Retell.

Three small changes in your Retell dashboard. We don't touch your Retell account — every change happens with your hands.

  1. 01

    Paste your Retell API key

    In our setup flow, paste a Retell API key with read access to your agents and permission to use the Calls API. We encrypt it at rest with your tenant DEK; it never lives in app memory longer than a single decrypt operation.

  2. 02

    Paste our webhook URL into your agent

    For each agent you connect we mint a unique webhook URL of the form https://redialer.io/api/webhooks/retell/wh_…. Drop it into your Retell agent's Agent Level Webhook URL. One URL per agent. Rotatable any time with a 24h grace window.

  3. 03

    Add one Boolean to your post-call extraction

    We watch for a single Boolean named redialer.io_callback in the post-call analysis output. When your agent flips it to true after a caller asks for a callback, we extract the requested time from the transcript tail and schedule the redial — respecting your quiet hours and retry policy.

    Voicemail, no-answer, busy, and technical-error retries are handled separately from the operator-facing Boolean. They're driven by Retell's disconnection_reason (or the provider's equivalent field), so your agent doesn't need any extra prompting for them.
