[Translate to English:] greenTalk Einrichtung der Rufnummer auf einer AVM FRITZ!Box

If you ordered a greenTalk phone number together with an Internet subscription, the phone number is configured automatically as soon as the FRITZ!Box has established an Internet connection.

If the phone number needs to be configured manually, you can complete the setup by following the steps below.

This guide explains how to set up your greenTalk phone number on an AVM FRITZ!Box. You can find the required SIP credentials in the customer portal under «Telephony».

Requirements

An operational FRITZ!Box with an Internet connection
Your greenTalk SIP credentials from the customer portal
Username and password for the FRITZ!Box

Note: Never share your SIP credentials with third parties and keep them in a secure place.

Accessing the FRITZ!Box

First, you need to connect to the FRITZ!Box user interface. Make sure that your computer is connected to the FRITZ!Box via a LAN cable or Wi-Fi. Then enter "fritz.box" or "192.168.178.1" in the address bar of your Internet browser (e.g. Firefox or Internet Explorer). The FRITZ!Box is already password-protected in its factory settings. You can find this password on the label on the back of your FRITZ!Box in the «FRITZ!BOX password» field. If you have not changed this password, you can use it to access the FRITZ!Box user interface.

Connect a computer to the FRITZ!Box.
Open a web browser.
Go to fritz.box or, alternatively, the IP address 192.168.178.1.
Log in using the password for your FRITZ!Box.

Adding a New Phone Number

On the left-hand side, navigate to Telephony > Telephone Numbers and then click «New Telephone Number».

2.2 Enter the Phone Number

Enter the SIP details (greenTalk credentials) and adjust the settings as shown in the image below. You can find the SIP details in your my.green customer portal under «Telephony».

Telephone number for registration

Enter the telephone number used for registration in this field. You received this telephone number from your provider. Its name may vary depending on the provider. Enter the telephone number exactly as specified by the provider, including any special characters it may contain.

Internal telephone number in the FRITZ!Box

Now enter your telephone number without the area code and without special characters.

Additional telephone number

Under "Additional telephone number", you can add further telephone numbers if they use the same credentials (username and password) as the first telephone number. You can set up telephone numbers with different credentials later under "Telephone Numbers" using the "New Telephone Number" button.

Enter the telephone number with the area code and without spaces
SIP username (14-digit number with a full stop)

Select the checkbox
Then click «Next»

2.3 Save the Phone Number

The FRITZ!Box now displays the credentials you entered.

Check the details.
Click «Next».

2.4 Check the Phone Number

Your FRITZ!Box now saves the credentials for your phone number and checks the connection. If the check fails, verify the settings according to section 2.2 Enter the Phone Number and check your Internet connection.

The FRITZ!Box then checks the connection to the greenTalk server.

If the check is successful, the phone number is activated and can be used.

If the check fails, verify the following:

Username and password
Telephone number including the area code
Internet connection
Registrar entry sip.green.ch

2.5 Assign the Phone Number to a Telephone

By default, your connected telephones respond to all configured phone numbers and use the first configured phone number for outgoing calls. Under the Telephony → Telephone Devices menu, you can change the behaviour of each telephone device by clicking the edit icon.

Once the setup has been completed successfully, the phone number can be assigned to a telephone device.
