# Callab AI

> AI calling platform for making and receiving phone calls with AI agents.

AI calling platform for making and receiving phone calls with AI agents. Best for voice-based customer interaction workflows -- outbound calling campaigns, inbound call handling, and phone-based AI assistants. Unlike Retell (voice agent infrastructure), Callab focuses on the calling platform layer with built-in agent orchestration.

2 example endpoints available through Lava's AI Gateway. See the [Callab AI API docs](https://docs.callab.ai) for full documentation.
