neither is displayed, use a web browser and access the configuration menu. Make sure the Registrar Server

Domain Name/IP Address is correct.

your status is unregistered, it means you do not have a SIP account. Contact your SIP service provider to get

an account.

Unplug the power cord from the IP phone. Wait 2 seconds and plug the power cord back in the IP phone.
