Troubleshooting Guidelines
68 4600 Series IP Telephone Release 2.2 Installation Guide
Discovering... CAUSE: The 46xx telephone is attempting to find a DHCP server.
RESOLUTION: If this message appears for more than a few seconds,
verify with the LAN Administrator that a DHCP server is appropriately
administered on the network. If there is not supposed to be a DHCP
server, you must “break into” the Discovering process and use static
addressing. See Static Addressing Installation
on page 39. To break into
the Discovering process, press the # button, and when you see the
“100Mbs” or “10Mbs” message, quickly press the * (asterisk) button.
Extension
Error
CAUSE: The PBX does not recognize the extension entered.
RESOLUTION: Confirm the extension is correct and is correctly
administered on the switch. Then try registration again, taking particular
care to enter the extension accurately.
Extension in
Use
CAUSE: The PBX detects an extension conflict with an existing set or
Softphone.
RESOLUTION: You can force the current telephone to register, and
thereby disconnect the other user, by pressing #. The 4600 Series IP
Telephone prompts you again for the Extension and Password. If you
enter the same Extension and Password, you are asked to confirm that
you want to unregister the original user. Press # to unregister the original
user and to register the current phone. Then press * to reset the phone
and enter a different Extension and Password.
Failed to set
phone IP
address
CAUSE: The 4600 Series Telephone was originally installed on one
switch with static addressing, and has subsequently been installed on
another switch with an active DHCP server assigning dynamic IP
addresses.
RESOLUTION: Reset the telephone.
File too large
Cannot save
file
CAUSE: The telephone does not have sufficient room to store the
downloaded file.
RESOLUTION: Verify the proper filename is administered in the TFTP
script file, and that the proper application file is located in the appropriate
location on the TFTP server.
Gateway Error CAUSE: DEFINITY Release 8.4 does not have an H.323 station
extension for this telephone.
RESOLUTION: On the station administration screen, ensure the DCP
set being aliased for this IP telephone has an H.323 station extension
administered, in accordance with switch administration instructions.
Hardware
failure
CAUSE: Hardware failure prevented downloading of application file.
RESOLUTION: Replace telephone.
