# How do I set up automatic prefixing?

{% tabs %}
{% tab title="sipgate classic" %}
You have the option of setting up an automatic area code for your cloud telephone system. If you enter a landline number without an area code, the previously defined area code will be used automatically. This is especially practical if you make many calls within one city.

{% hint style="info" %}
**Important:** This function can only be set for landlines. Therefore, for calls on the mobile network, you must continue to use an area code.
{% endhint %}

Go to **My Telephony** and then in the left navigation menu to **Telephony**. Here you can select the phone for which the settings are to be made. To do this, click the icon with three dots. Now select the item **More settings.**

{% tab title="sipgate neo" %}
With the automatic area code, you can store a fixed local area code for a device. If you then select a landline number without an area code, the saved area code is used automatically. This is especially helpful for frequent calls within a certain area code region.

{% hint style="info" %}
**Important:** The automatic area code only works for landline numbers. For mobile numbers, the full area code must still be entered.
{% endhint %}

**How to activate or change the automatic area code**

## 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://help.sipgate.de/cloud-telefonanlage/en/using-sipgate/telefonie/wie-richte-ich-die-automatische-vorwahl-ein.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.
