# redialer.io > Automated callbacks for AI voice & SMS agents. When your agent promises a follow-up, or a call hits voicemail, no-answer or busy, redialer.io schedules and delivers the redial on time — built for Retell. redialer.io is a callback scheduler for AI phone agents. Your voice agent handles the live conversation; redialer.io places the outbound follow-up call (or SMS) at the requested time, automatically. It ingests Retell webhooks, detects each call outcome, and redials according to your retry rules — with per-agent quiet hours, quiet days, and tier-gated retry delays. ## Core pages - [Home / how it works](https://redialer.io/): Overview of the callback flow. - [Features](https://redialer.io/features): Webhook ingestion, outcome detection, retry rules, quiet hours. - [Pricing](https://redialer.io/pricing): Plan tiers and limits. - [Security](https://redialer.io/security): Data handling, authentication, and infrastructure posture. - [Docs](https://redialer.io/docs): Step-by-step guide for connecting a voice agent. ## Integrations - [Retell](https://redialer.io/retell): Primary integration — webhook setup and post-call extraction. - [Vapi](https://redialer.io/vapi): Coming soon. - [Bland](https://redialer.io/bland): Coming soon. ## Legal - [Privacy](https://redialer.io/privacy): Privacy policy. - [Terms](https://redialer.io/terms): Terms of service.
