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

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

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

{% step %}

#### Find sipgate login data

Log in to your **sipgate trunking account** . Click the **Trunking** tab and then click the row in which your phone system is stored. Scroll **down** to the section **SIP account data**. Here you will find the access data that must later be entered in the FRITZ!Box.
{% endstep %}

{% step %}

#### Create 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 under **Telephone provider sipgate trunking**. Enter one of your phone numbers in both phone number fields without area code and country code. If you want to store **multiple phone numbers** please click the button **Additional phone number** and create the phone number(s) as described above.

**Note:** If an alternative caller ID number 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 **Username** field. Enter your SIP password in the **Password** field. You can find both in the SIP account data section. You can take the other settings from the screenshot below. Which Internet protocol you select under **Contact Internet telephony provider** depends on your provider and may need to be tested in the various variants. Click **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 successful registration. All other phone numbers that you have additionally stored are displayed with a **gray dot** but are still reachable.

{% endstep %}
{% endstepper %}

## Set up area code

In the FRITZ!Box menu, click under **Own phone numbers** on the tab **Connection settings**. Under **Location information** enter the country code and area code that should be dialed before the selected number when calling your local network.

## Link telephones with phone number and set caller ID number:

In the **Telephony** area of the FRITZ!Box, click on the tab **Telephony devices**. Set up your phone(s) here. Since there are various options here, you should consult the information in AVM's knowledge base. In our example, there are two DECT phones. When the phone is displayed 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 called party for outgoing calls. Select under **Incoming calls** the phone number(s) to which the respective phone should respond.

In this example, the phone **OFFICE** displays the phone number of the **CENTRAL** for outgoing calls, but is reached via a different number for incoming calls.

{% hint style="info" %}
**Important:** Please note that the FRITZ!Box only allows a limited number of parallel calls. More information on the topic can be found here [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 misbehavior (for example, problems with outgoing calls). In this case, we ask you to upgrade to the above-mentioned version.
