Issues such as this are typically caused by connection issues where the phone isn't connected to the internet via a router and can be resolved easily. 

Please check the following:

1. Can you access the internet from the router that is connecting your VoIP line?

2. Have you unplugged your router and then re-booted?

3. Have you switched off/unplugged your desk phone and then re-booted?

4. Is your phone correctly connected with the Ethernet cable (for a Desk phone this needs to be attached to the 2nd socket with the 3 boxes on the back of the phone as shown below). 

5. Can you get an IP address from your Gigaset Desk Phone?  Please click here to find out how to get this.

6. Can you get an IP address from your router?  To check this connect a PC/laptop directly to the router and type into a web browser 'what is my IP address?'

8. If you are on a Dynamic IP please check that DHCP is enabled on your router?

10. Have you done a factory re-set of the phone?
