# Conversation Behavior – Start Conversation

Choose whether the caller speaks first or your AI voice agent opens with a dynamic, prompt-based message or a single predefined line.

This feature allows you to configure who initiates the conversation.

**Options:**

**Conversation Start Behavior**

* User Initiates
* AI Initiates (Dynamic Message – Based on Instructions)
* AI Initiates (Predefined Message)

The options to define who starts the conversation are:

* **User Initiates:**

  With this setting, the AI agent will wait for the user to speak first to start the conversation.
* **AI Initiates (Dynamic Message – Based on Instructions):**

  If you choose this option, the AI agent will start the conversation with dynamically generated messages. These messages will be created based on the instructions or “prompt” you have configured for the agent.
* **AI Initiates (Predefined Message):**

  By selecting this option, the AI agent will start the conversation using a single, specific message that you have previously defined in your prompt.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.dapta.ai/ai-voice-agents/how-to-set-up-your-ai-voice-agent/voice-agent-settings-guide/conversation-behavior-start-conversation.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
