User Guide for the CP920 HD IP Conference Phone
146
Why does the phone display "Network unavailable"?
Ensure that the Ethernet cable is plugged into the Internet port on the phone and the
Ethernet cable is not loose.
Ensure that the switch or hub in your network is operational.
Why does the phone display “No Service”?
The LCD screen displays “No Service” when no SIP account registers successfully.
Why doesn’t the phone display time and date correctly?
Check if you have configured the phone to obtain the time and date from the SNTP server
automatically. If the phone fails to connect to the SNTP server, you need to configure the time
and date manually.
