Prerequisites for the following steps
Before you start, you need to know your VoIP username, password and the SIP server address of your VoIP provider. For the purpose of this guide, let's assume my VoIP provider account information is as follows:
  • VoIP Username as my VoIP username
  • Password as my password
  • as my VoIP providers SIP server
Step 1: Registering your handset
On your handset, select the following Menu > Settings > Registration > Register Handset. It will ask you for a system PIN, this is 0000. Before you enter the PIN, press and HOLD the silver button (Glows Blue) on your base station for 3 SECONDS and let go, enter the PIN and this will register the handset.

Step 2: Locating the IP address
You can obtain the IP Address two different ways. You can either type in into the address bar of your web browser OR click on menu > settings > System > Network > IP Address. If you cannot see this option, your handset will need registering (See above step). DO NOT include any leading zeros, so should actually be typed into your web browser. You should see the following login screen:
