# How do I book phone numbers?

At sipgate, you have the option, **German local-** and **mobile numbers** as well as **international numbers** and **extensions** to book. Here's how it works:

#### German local and mobile numbers

As an admin, you can in the account under the navigation item **Phone numbers** using the button **Book** select local and mobile numbers.

If you have multiple locations set up, when booking local numbers you can select the desired location and thus the desired area code.

After you have **number of phone numbers** selected, you will be shown the available numbers that you can then book.

To be able to receive and use German phone numbers, you need at least one location in Germany, which you must verify. International numbers can be booked without verification.

#### International numbers

With international numbers, you enable customers to make a local call from abroad.

1. **Select country**: Select the desired country and the appropriate **area code range**.
2. **Check verification documents**: Upload the required **proof of address** documents (varies by country).
3. **Enter company details**: Enter your **details in the selected country** in.
4. **Select or create location**: Select an existing or new **location in the destination country**.
5. **Use phone number**: After successful verification, the number appears in the account and can be integrated into the **Routing** be integrated.

{% hint style="info" %}
**Note**

* In many countries, a valid address is sufficient as proof.
* Numbers are usually **available after a few minutes** available, with additional documents **after approval**.
  {% endhint %}

The following also applies:

* You cannot book international numbers in bulk.
* A maximum of four simultaneous incoming calls is possible.
* International numbers cannot be used for incoming fax, SMS, or data communication.
* If an international number is set as the sender ID, calls or faxes to special numbers such as 0800 may be partially unavailable.
* International numbers cannot be listed in public telephone directories.
* You cannot take your international numbers with you (port them).
* For legal reasons, we cannot guarantee that when making a call to a non-European country, the international number will be transmitted. Within the European Economic Area (EEA), whether your number is transmitted depends on the called party's telephone company. In individual cases, it may therefore happen that your German phone number is displayed instead of the international number.

Further information on the current legal situation can be found in the [Telecommunications Act](https://www.gesetze-im-internet.de/tkg_2021/__120.html) as well as in the [Federal Network Agency's order 44/2022 on the Telecommunications Act](https://www.bundesnetzagentur.de/SharedDocs/Downloads/DE/Sachgebiete/Telekommunikation/Verbraucher/Rufnummernmissbrauch/Amtsblattverfuegungen/Vfg10_2022.pdf?__blob=publicationFile\&v=3).

#### Test phone numbers

If you want to test sipgate, during the trial period you have **five test numbers** with the Düsseldorf area code 0211 at your free disposal. These numbers are **usable for 30 days** and then expire automatically, so you must book your own numbers by then at the latest. The test numbers can be reached from any German line. However, you cannot be called on these numbers from abroad during the trial period.

{% hint style="warning" %}
**Important note:** your **Test numbers expire**, as soon as you in your account

* to the **regular contract** switch
* Your **top up credit**
* Your **cancel contract**
* or a **redeem voucher**
  {% endhint %}
