Operational Errors and Status Messages
Cause/Resolution
CAUSE: Loss of power.
RESOLUTION: Check the connections
between the telephone, the power supply, and
the power jack. For example, verify that either
static addressing was not used or that any
changes to static addresses were entered
correctly.
CAUSE: Loss of path to Avaya Media Server,
DHCP Lease expired, or DHCP server not
available when telephone attempts to
renegotiate DHCP lease.
RESOLUTION: As above.
CAUSE: Loss of power.
RESOLUTION: Check the connections
between the telephone, the power supply, and
the power jack.
CAUSE: Loss of communication with the call
server.
RESOLUTION: Check LAN continuity from the
call server to the telephone using ARP or
trace-route and from the telephone to the call
server by invoking a Feature button. Verify that
LAN administration has not changed for the
Gatekeeper, TN 2302AP boards, or the LAN
equipment (routers, servers, etc.) between the
switch and the telephone. Verify no one
changed the telephone settings locally using the
VIEW and ADDR codes, as described earlier in
this guide. Verify the telephone volume is set
high enough. Finally, conduct a self-test.
CAUSE: Loss of communication with the call
server.
RESOLUTION: As above, but pay particular
attention to the possibility that the telephone is
being routed to a different DHCP server, or even
a different call server switch. If so, the new
server or switch might need to be administered
to support the telephone.
CAUSE: Loss of communication with the call
server.
RESOLUTION: As above.
