# DialNexa Agent Settings Overview

> Understand DialNexa agent settings, including functions, custom functions, speech settings, call settings, fallback variables, post-call analysis, and agent webhooks.

DialNexa agent settings control what a published agent version can do during and after a call. They cover tools, speech behavior, call timing, fallback variables, post-call extraction, and webhook event enablement.

<Note>
  The prompt tells the agent what to say. Settings decide what happens when the caller goes silent, asks for a booking, triggers a transfer, or leaves data behind.
</Note>

## Settings And Version State

Many settings belong to the agent version, so version state matters.

| State             | User expectation                                                                          |
| ----------------- | ----------------------------------------------------------------------------------------- |
| Draft version     | Most settings can be edited and tested.                                                   |
| Published version | Some controls are disabled to protect live behavior.                                      |
| New version       | Use a new draft when changing behavior for production.                                    |
| Assigned version  | Phone numbers, batch calls, and workflows should point to the intended published version. |
