Troubleshooting
If your IP phone does not operate as you expect, check the following
points before reporting a fault to your phone services manager:
1) No dial tone
•
Check that the IP phone is plugged in to the IP network;
•
Check that the power supply is plugged in and switched on.
2) Phone does not ring
•
Handset has not been properly hooked;
•
Your calls are diverted (you hear a special tone when you lift the
handset and the upper line of the display usually shows the
telephone number to which calls are diverted);
•
Do not disturb is set;
•
Follow me has been activated;
•
The ringing volume is too low.
3) Cannot dial an external number
•
You do not have the privilege. Contact your system administrator
to check.
4) The system does not recognize your User ID or your PIN
•
Try to log in again to confirm that you did not make a mistake
when you entered your User ID and PIN.
•
If you receive the error message again, contact your system
administrator to check that you have the correct User ID and PIN.
5) LCD display appears to have rolling lines or a wavy pattern
•
It might be interacting with certain types of older fluorescent lights
in the building. Moving the phone away from the lights, or
replacing the lights.
