Troubleshooting
This chapter provides general troubleshooting information to help you solve the problems you
might encounter when using your CP860 IP conference phone.
If you require additional information or assistance with your new phone, contact your system
administrator.
General Issues
How do I find the basic information of the IP phone?
Press the OK key when the IP phone is idle to check the basic information of the IP phone, such
as IP address and firmware version. For more basic information, refer to Phone Status on page
17.
How to obtain the MAC address of a phone when the phone is not powered on?
Three ways to obtain the MAC address of a phone:
 You can ask your supplier for the shipping information sheet which includes MAC addresses
according to the corresponding PO (Purchase Order).
 You can find the MAC address on the label of the carton box.
 You can also find the MAC address from the phone’s bar code on the back of the phone.
What is the difference between user name, register name and display name?
Both user name and register name are defined by the server. A user name is used to identify the
account, while a register name matched with a password is used for authentication if the server
requires. Display name is the caller ID that will be displayed on the callee’s LCD screen. Server
configuration may override the local configuration.
Why can’t I send an SMS to any other phone?
SMS depends on support from a SIP server. Contact your system administrator for more
information.
Display Issues
Why is the LCD screen blank?
 Ensure that the phone is properly plugged into a functional AC outlet.
 Ensure that the phone is plugged into a socket controlled by a switch that is on.
