Please check the phone is correctly connected up to your broadband network - making sure the correct network cables are used. 

Can you get an IP address from the phone?

Please check your network cable - try a different cable to see if this then works as it could be due to a faulty network cable. 

How is your phone connected to the network, for example are you using a switch or is the phone connected directly to a router? 

Can you disable the firewall on your network to see if this then resolves the issue? 

Can you also disabled SIP ALG on your router and set your router for Quality of Service so that VoIP traffic is prioritised over internet traffic. 

If you can please supply as much information as possible and contact our Support Helpdesk for further assistance.
