# Yapper

{% hint style="info" %}
Yapper (Yapper Ping) has a cooldown of 1 hour.
{% endhint %}

## How it works

* Yapper links roles to Voice Channels
* When anyone joins the Voice Channel, and they are the person in the Voice Channel, Nalu will wait 10 seconds before sending the message: "@{roles}, @{user} just started a call in #{channel}!"

## Cases where Yapper will not activate

* The user who has joined the call is a bot
* The user who has joined the call leaves before 10 second grace period has been reached
* The call is already populated
* The channel's cooldown is active
