# 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.
