CAUSE: Loss of communication with the PBX switch.

RESOLUTION: Check LAN continuity from the PBX to the telephone using ARP or trace-route and from the telephone to the PBX 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 in the 4600 Series IP Telephone Installation Guide. Verify the telephone volume is set high enough. Finally, conduct a self-test.

CAUSE: Loss of communication with the PBX.

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 PBX switch. If so, the new server or switch might need to be administered to support the telephone.

AND the network was recently changed to upgrade or replace servers, re-administer the Avaya Media Server, add or change NAT, etc.

CAUSE: Loss of communication with the PBX.

RESOLUTION: As above.
