# Manage number pools in the app

> Manage an agent's phone numbers in the app, and load an earlier version into your draft without going live.

One agent can now use several phone numbers, and you manage them all from its deployment settings. Add or remove numbers there, and pick which number calls you when you test a call. See [Number Pooling](/number-pooling).

## Revert a version into your draft

![Revert Version menu offering Revert, which loads the version into the draft, and Revert and publish, which makes it live as a new version](https://storage.googleapis.com/granular-changelog/doc-images/changelog_revert.png)

If a revert put the wrong configuration live, you had to publish again to undo it. Restoring a version now offers **Revert**, which loads it into your draft so you can test and edit it first. **Revert and publish** still makes it live right away. See [Restore this version](/version-control#restore-this-version).
