Operational errors and status messages
Cause/Resolution
CAUSE: Loss of power.
RESOLUTION: Check the connections between
the deskphone, 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 deskphone using ARP or
trace-route and from the deskphone to the call
server by invoking a Feature button. Verify that
administration has not changed for the LAN
equipment (routers, servers, etc.) between the
call server and the deskphone. Verify no one
changed the deskphone settings locally using
the VIEW and ADDR craft procedures, as
described earlier in this guide.
CAUSE: Loss of communication with the call
server.
RESOLUTION: As above, but pay particular
attention to the possibility that the deskphone is
being routed to a different DHCP server, or even
a different proxy server. If so, the new server
might need to be administered to support the
deskphone.
CAUSE: Loss of communication with Session
Manager.
RESOLUTION: As above.
