Do one of the following:
If your device connects to the wired network:
l
Ensure that the Ethernet cable is plugged into the Internet port on the IP phone and the Ethernet cable is not
loose.
l
Ensure that the Ethernet cable is not damaged.
l
Ensure that the IP address and related network parameters are set correctly.
l
Ensure that your network switch or hub is operational.
Time and Date Issues
Display time and date incorrectly
Check if the IP phone is configured to obtain the time and date from the NTP server automatically. If your phone is
unable to access the NTP server, configure the time and date manually.
Phone Book Issues
Difference between a remote phone book and a local phone book
A remote phone book is placed on a server, while a local phone book is placed on the IP phone flash. A remote
phone book can be used by everyone that can access the server, while a local phone book can only be used on a
specific phone. A remote phone book is always used as a central phone book for a company; each employee can
load it to obtain real-time data from the same server.
