When I attempted to
reboot or change
software, the IP Phone
locks up.
Phone lock-up maybe caused by an error in transport during the
software upgrade. To correct this problem:
1. Disconnect power from the IP Phone.
2. Press and hold the [Up] and 2 button while reapplying
power.
3. Release the buttons when the Message LED extinguishes.
4. When the BootC screen appears, enter the digits 1, 2, 3
and 4.
5. Follow the prompts to configure IP parameters for the IP
Phone.
6. At the “Server Addr?” prompt, enter the TFTP server
address where the IP Phone can find the BootC firmware.
If already correct, press the [Next] button.
7. At the “Do you want to apply default?” prompt select the
[Yes] softkey to use default or [No] softkey to use
previously assigned parameters.
The IP Phone will reboot and return to normal operation.
