Telephones—Continued
Error Message
No Ethernet
No file server address
System busy
Extension error
Extension in use
Cause/Resolution
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, verify power is applied on the LAN to that
jack, etc.
CAUSE: The TFTP 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 TFTP server, or
administer the telephone locally using the ADDR option as
detailed in the 4600 Series IP Telephone Installation Guide.
CAUSE: Most likely, the number of IP endpoints on the DEFINITY
is already at maximum, Less likely, network resource is
unavailable.
RESOLUTION: The telephone was attempting to access a
network resource (DHCP server, TFTP server, or the DEFINITY)
and was not successful. The resource being called upon should
be checked for its availability. If it appears operational and
properly linked to the network, verify addressing is accurate and a
communication path exists in both directions between the
telephone and the resource.
During Registration
CAUSE: An invalid DEFINITY Registration extension has been
entered.
RESOLUTION: Re-enter the extension if mis-entered initially. If
appropriate, verify proper extension with respect to switch
administration.
CAUSE: The specified extension is already in use, according to
the DEFINITY switch.
RESOLUTION: Wait a few minutes, and try again. This will work
for the case when the extension is correctly administered, but
service was interrupted and DEFINITY is not yet aware of that
fact. Otherwise, verify proper extension with respect to switch
administration.
