# Use cases

> Longer builds that solve a whole job rather than demonstrating one setting.

The quickstarts get an agent working. These go further and build the thing you
actually wanted, end to end, including the parts that usually get skipped.

Each one assumes you have done at least one quickstart, so they do not re-explain
voices, prompts or how to save an agent.

## Pick a job

<Steps>
  <Step title="A clinic phone that never stops">
    **[Book appointments for a clinic](./clinic-appointments)**

    An inbound agent that books into a real calendar, collects an email, and agrees a
    callback when there is no slot the caller wants.
  </Step>
</Steps>

## What these assume

* You have an agent that works. If not, start with
  **[Quickstart](/product/quickstart/index)**.
* You have at least one phone number. See **[Numbers](/product/features/numbers)**.
* You are comfortable testing an agent before pointing it at real people. See
  **[Testing an agent](/product/features/agent-testing)**.
