Power and Startup Issues
Both PoE cable and power adapter is connected to the phone
The phones use the PoE preferentially.
The IP phone has no power

l
Reboot your IP phone.
l
Replace the power adapter.
The Phone screen is black
If the power LED indicator is on, the keypad is usable but the phone screen is black, please reboot your IP phone.
Other Issues
The difference among user name, register name and display name
Both user name and register name are defined by the server. User name identifies the account, while register name
matched with a password is for authentication purposes. The display name is the caller ID that will be displayed on the
callee’s phone touch screen. Server configurations may override the local ones.
On code and off code
They are codes that the IP phone sends to the server when a certain action takes place. On code is used to activate a
feature on the server side, while off code is used to deactivate a feature on the server side.
For example, if you set the Always Forward on code to be *78 (may vary on different servers), and the target number to
be 201. When you enable Always Forward on the IP phone, the phone sends *78201 to the server, and then the server
will enable Always Forward feature on the server side, hence being able to get the right status of the extension.
For anonymous call/anonymous call rejection feature, the phone will send either the on code or off code to the server
according to the value of Send Anonymous Code/Send Rejection Code.
