# Overview

> Search persisted conversation history across supported Telnyx communication sources.

Conversation History stores and indexes conversation records so your agents can search previous interactions and use them as memory or retrieval context.

## How It Works

1. Enable conversation persistence on a supported source.
2. Telnyx stores and indexes the conversation record.
3. Search the indexed history by text, record type, region, and filters.
4. Use search results as retrieval context for RAG.
