# What is the Presence Display (Busy Indicator)?

In your sipgate account, you'll find the **Presence Display** under **My Telephony**. This feature shows which users are currently available and serves as an alternative to a busy lamp field.

If a user is on a call, their tile—showing their internal extension—will turn red.

{% hint style="info" %}
**Important:** Each user must be assigned an internal extension for this feature to work.
{% endhint %}

#### Using the Presence Display

* In the left-hand navigation bar, you'll find the **Presence section** with all internal extension numbers.
* Clicking an extension will start a call to that colleague.
* If an extension is busy, its tile will appear red. If it's being dialed, the tile will have a red border, and the user's name will move.
* You can still place a call to a busy extension if needed.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://teamhelp.sipgate.co.uk/use-sipgate/telephony/what-is-the-presence-display-busy-indicator.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
