Siemens DX800A Series

Prerequisites

Before you start, you need to know your VoIP username, password and the server that your number is connected to. You can do this from your Soho66 account, by clicking My Soho, then "Your Numbers", then the telephone number that you wish to connect to. The VoIP username and VoIP password are near the bottom of the page, in a section entitled VoIP Settings.

Step 1: Locating the IP address

You can obtain the IP Address two different ways. You can either type in gigaset-config.com into the address bar of your web browser OR click on Menu > Settings > System > Local Network > IP Address as in the image below:

Once you have the IP address (in this case 192.168.1.5), type it into your address bar of a web browser (where you type www.google.com) and it should then load the DX800A login page as below:
