# Retell

> Voice agent platform for creating and managing AI-powered phone calls with built-in AI agent logic, conversation flow control, and real-time transcription.

Voice agent platform for creating and managing AI-powered phone calls with built-in AI agent logic, conversation flow control, and real-time transcription. Best for automated outreach, appointment reminders, and voice-based data collection where the AI handles the full conversation. Unlike ElevenLabs (text-to-speech synthesis) or raw telephony APIs, Retell manages the entire call lifecycle — from dial to hang-up — with an AI agent driving the conversation.

2 endpoints available through Lava's AI Gateway. See the [Retell API docs](https://docs.retellai.com/api-references) for full documentation.

<Info>Supports both **managed** (Lava's API keys) and **unmanaged** (bring your own credentials) mode.</Info>
