# Gigaset VoIP Phones
## Configuring your Gigaset VoIP Phone for Kiwi VoIP.
Remove the contents of your Gigaset box and connect them to your router and power source. You will notice that all the required cables are in the box, including the ethernet cable for connectivity between your router/switch and the device’s base unit.
Below are detailed instructions on configuring the Gigaset series to work with Kiwi VoIP’s service:
**1. Reset your Gigaset to factory default settings**
If you purchase a second hand Gigaset device or one that has been setup to work with a particular carrier then the safest bet is to reset the settings to the factory defaults so that you start with a clean slate and can be sure that some previously entered setting is not causing you a problem. To reset the Gigaset to factory defaults follow these steps:
Remove all connections from the base unit
Hold the blue button on the front of the base unit
Continue to hold the front button whilst inserting the power cable to the rear of the unit
Wait 10 seconds then release your finger from the button
The base station has now been reset
**2. Get access to your Gigaset web interface**
Plug in Ethernet cable to router and wait for several seconds
Navigate to [http://www.gigaset-config.com/](http://www.gigaset-config.com/)
Wait until your device is detected and you are forwarded to the login page
Enter your PIN number (the default is 0000)
You should now see the Gigaset Web Interface
Select ‘Telephony’ on the left hand side of the page, you will now be shown a list of connections
add more they can be done in the same fashion.
Select edit on line 1 and you will be shown a configuration page for that line
Enter the following information in the fields:Authentication Name: The phone number you want set to this line
Authentication Password: Your Kiwi VoIP password for this phone number
Username: The phone number you want set to this line

##### Troubleshooting Tips
If you are still having problems getting your A580IP to register with Kiwi VoIP then you can try disabling or enabling the STUN settings.
Another thing you can try is changing your SIP Port from ‘5060’ to ‘50600’ (and 5061 to 50610 on line 2 if required).
