# How Team Follow Up works

> The whole system in one picture: an agent that talks, and a campaign that decides who to call and when.

Team Follow Up makes phone calls for you. Real calls, to real people, in a real
voice. You set it up once, and it calls your leads for you, all day, without
getting tired.

The whole system is really just two pieces. Once you get these two, you get
everything.

## The agent: the voice that talks

An **agent** is the caller. It's a voice that runs on a computer and talks like a
person. You give it a goal (book a meeting, get someone on the phone) and a few
rules, and it handles the conversation on its own.

You don't script every word. You brief it, the way you'd brief a new hire on
their first day, then let it do the talking.

## The campaign: the plan for calling

An **agent** on its own is just a voice with nothing to do. A **campaign** is the
plan that puts it to work. The campaign answers the practical questions:

* Who do we call?
* What hours are we allowed to call them?
* How many times, and how far apart?
* What number shows up on their phone?

The campaign feeds people to the agent, one at a time, and the agent calls them.

## What happens after a call

Every call ends. When it does, the agent decides **what happened** (they booked,
they asked for a callback, they said stop calling) and writes down the useful
bits. Then the campaign can act on that: send a text, add a label, try again
tomorrow, or leave them alone.

So the loop is simple:

<Steps>
  <Step title="The campaign picks someone to call">
    Based on your list, your hours, and your schedule.
  </Step>

  <Step title="The agent makes the call">
    It talks, listens, and works toward the goal you gave it.
  </Step>

  <Step title="The call gets an outcome">
    The agent decides what happened and records it.
  </Step>

  <Step title="The campaign follows up">
    Text, tag, retry, or stop, based on that outcome.
  </Step>
</Steps>

That's the engine. The rest of these guides just zoom in on each part.
