AVM FRITZ!Box - All models

For best reliability and security, please always make sure that your AVM Fritz!Box is running the most recent firmware version available.

You'll need your SIP-ID and SIP password (not your web login password) to set up the Fritz!Box for sipgate services.

To access the device management, please navigate to fritz.box from a computer connected to the Fritz!Box.

If your device does not support using the URL please check AVM's device manual. It will list a default IP address to use for management access.

Please open the section Telephony -> Telephone Numbers and click on the New Telephone Number button. 

In the drop-down provider list please choose Other Provider and enter the following details:

User name: Your SIP-ID

Password: Your SIP Password

Registrar: sipgate.co.uk

Proxy Server: sipgate.co.uk

Telephone Number for Registration: 44[YourAreaCode][YourSipgatePhoneNumber] (Example: 442031234567)

Internet Telephone Number: 0[YourAreaCode][YourSipgatePhoneNumber] (Example: 02031234567)

If the option Relay outgoing emergency calls without prefixes is displayed please enable it. 

Some internet service providers provide a second, separate internet connection for telephony. This connection can only be used with the internet service provider's phone numbers. If available, please enable the option Always register via an Internet connection so that your sipgate calls use the same connection used for regular internet traffic.

Please click Next and confirm your changes. Your Fritz!Box will now try to connect with sipgate:

In the Fritz!Box Telephony Devices menu you can choose which phone handsets will be used with your sipgate account.

Testing your Configuration:

To test your phone's configuration, please dial the following sipgate numbers:

• 10000
• 10005
• 10020

If you're experiencing issues with registering online:

• Open Telephony -> Telephone Numbers and click the button (Edit) next to your sipgate account. 
• If the registration failure reason is "Internet telephony registration failed [number] Reason for error: [401, 402, 403]" check that your SIP-ID, SIP password and the server address sipgate.co.uk are entered correctly. 
• If the field STUN server is shown under your account information, please enter the sipgate STUN Server address: stun.sipgate.net. This setting should be disabled again if it doesn't help resolve the issue.
• If your Fritz!Box is connected behind another router you may need to set up Port Forwarding.  AVM describe the process in detail in their help centre.

If you're experiencing issues with making outbound calls:

• Please open Telephony -> Telephone Numbers -> Line Settings. 
• Select Other country from the drop-down list.
• Enter the Country Code 00 44 and leave the Area Code blank.
