# How do I set up automatic prefix dialing?

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

{% hint style="info" %}
**Important:** This feature can only be set for landline phones. Therefore, for calls on the mobile network, you will still need 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 should be made. To do this, click the icon with three dots. Now select **Additional settings.**

{% tab title="sipgate neo" %}
With 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 stored area code will be used automatically. This is especially helpful for frequent calls within a certain area code region.

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