# New dialog from a contact

The **New dialog** feature allows agents to initiate contact (write/call) with new customers.

You can start interacting with new customers first through the following Inboxes: 

* API Inbox (available for WhatsApp and Telegram messengers) 
* Telegram by phone
* Viber by phone
* Call 
* Email

{% hint style="warning" %}
The option is available only if there is a channel from which you can write to a new client first (to do this, you need to activate the **Can write first to a new client** option in the [Inbox](/en/get-started/settings/inboxes/api.md#main-settings) settings). 

For Inboxes with the Call and Email conversation types, this option is enabled by default.
{% endhint %}

Outside of the 24-hour customer service window, you can only send [HSM templates](/en/get-started/conversations/conversation-panel/hsm-templates.md). As soon as the customer replies to the template message, a new 24-hour window for communication opens.
