140 4600 Series IP Telephone LAN Administrator Guide
Cause/Resolution
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.
CAUSE: Hardware failure prevented downloading of
application file.
RESOLUTION: Replace telephone.
CAUSE: The telephone has detected an IP Address
conflict.
RESOLUTION: Verify administration to identify duplicate
IP Address(es).
CAUSE: A device between the telephone and the call
server is invoking Network Address Port Translation, which
the 4600 Series IP Telephones do not support.
RESOLUTION: Remove or re-administer the NAPT device
or move the telephone.
CAUSE: When first plugged in, the IP telephone is unable
to communicate with the Ethernet.
RESOLUTION: Verify the connection to the Ethernet jack,
verify the jack is Category 5, etc. Note that if the telephone
is attached to a 30A switched hub, upon loss of Ethernet
connectivity, the usual "No Ethernet" message is not
displayed.
CAUSE: The file server IP Address in the IP telephone's
memory is all zeroes.
RESOLUTION: Depending on the specific requirements of
your network, this may not be an error. If appropriate,
either administer the DHCP server with the proper address
of the file server, or administer the telephone locally using
the ADDR option. The 4600 Series IP Telephone
Installation Guide explains the ADDR option.
CAUSE: The telephone has registered with the call server,
but network problems have prevented the telephone from
opening a TCP socket.
Note: This message only occurs on older software
versions. Telephones with newer software automatically
reset.
RESOLUTION: Investigate the network problem normally.
