# What can I do if the area code is automatically dialed?

When calling internal extensions, it can often happen that they are dialed with an automatically inserted prefix and therefore no connection is established to the desired destination. When using a **AVM FRITZ!Box** this automatic prefix can be disabled with just a few clicks.

To do this, under the menu item **Telephony** under **Own phone numbers** the stored sipgate number must be edited. After opening the sipgate number for editing, first the telephony provider above must be changed from **sipgate** on **Other providers** which then opens up further configuration options.

In the section **Phone number format** it can now be selected whether a country or area code should also be dialed. Here, simply choose the setting for both options **None** and then save by clicking on **OK**.

## 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/allgemeine-losungen-beim-telefonieren-mit-sipgate/was-kann-ich-tun-wenn-die-vorwahl-automatisch-mitgewaehlt-wird.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.
