# How do I set up sipgate trunking on an AVM FRITZ!Box 7590?

You can configure a sipgate trunk in a FRITZ!Box 7590. You can find out exactly how this works and how phone numbers are created here. You will also find an explanation of how end devices are linked to phone numbers and how outgoing caller IDs are set.

## Register AVM Fritz!Box 7590 with sipgate (FRITZ!OS 06.60) and create phone numbers

{% stepper %}
{% step %}

#### Find sipgate login details

Log in to your **sipgate trunking account** . Click on the tab **Trunking** and then on the line where your phone system is stored. Scroll **down** to the section **SIP account data**. Here you will find the login details that will later need to be entered in the FRITZ!Box.
{% endstep %}

{% step %}

#### Create a phone number in the FRITZ!Box

Then log in to the overview page of your FRITZ!Box. Click here on **Telephony** and **Own phone numbers**. Now select **New phone number** and for the **sipgate trunking telephone provider**. Enter one of your phone numbers without area code or country code in both phone number fields. If you want to store **multiple phone numbers** , please click the button **Additional phone number** and create the phone number(s) as described above.

{% hint style="info" %}
**Note:** If an alternative outgoing caller ID is to be used, it must be stored here, even if it is not part of the sipgate account.
{% endhint %}
{% endstep %}

{% step %}

#### Enter SIP data and complete registration

Enter your SIP ID in the field **Username** . In the field **Password** enter your SIP password. You can find both in the SIP account data section. The other settings can be seen in the screenshot below. Which internet protocol you should select under **Contact Internet telephony provider** depends on your provider and may need to be tested in the various versions if necessary. Click on **Next** and complete the registration. Your phone number(s) will now be displayed in the phone number overview. A **green dot** in front of the phone number indicates a successful registration. All other phone numbers you have additionally stored will be shown with a **gray dot** but are still reachable.

{% endstep %}
{% endstepper %}

## Create area code

In the FRITZ!Box menu, click under **Own phone numbers** on the tab **Connection settings**. Enter under **Location information** the country and area code that should be prefixed when calls are made to your local network for the selected phone number.

## Link telephones to phone numbers and set outgoing caller ID:

In the **Telephony** section of the FRITZ!Box, click on the tab **Telephony devices**. Set up your telephone(s) here. Since there are various possibilities here, you should consult the information in AVM's knowledge base. In our example, these are two DECT telephones. When the telephone is shown in the overview of telephony devices, click on the **edit icon**. Please select under **Outgoing calls** the phone number that should be displayed to the person called for outgoing calls. Select under **Incoming calls** the phone number(s) to which the respective telephone should respond.

![FRITZ!Box telephony devices](/files/b6b5c860f87f6401421f0e960a55425015ddaa07)

In this example, the telephone **OFFICE** shows the phone number of **HEAD OFFICE** for outgoing calls, but is reached on a different number for incoming calls.

{% hint style="info" %}
**Important:** Please note that the FRITZ!Box only allows a limited number of parallel calls. You can find more information on the topic [maximum number of calls via the FRITZ!Box](https://avm.de/service/fritzbox/fritzbox-7490/wissensdatenbank/publication/show/421_Maximale-Anzahl-Gespraeche-ueber-FRITZ-Box/).

A configuration on end devices with older firmware can cause incorrect behavior (for example, problems with outgoing calls). In this case, please upgrade to the version mentioned above.
