Description
The IP Phone KEM display flashes until it establishes
communication with the IP Phone.
If the IP Phone KEM display does not stop flashing,
communication has not been established with the IP Phone.
Check that the IP Phone KEM is correctly installed and
configured.
The key labels download to the IP Phone KEM. During the
download, the display is blank.
When the three phases complete successfully, you are ready to use the
additional line/feature keys on your IP Phone KEM.
Note: If you have a second IP Phone KEM installed on your IP Phone,
the one to the immediate right of the IP Phone must be functional for the
subsequent IP Phone KEM to work. This is because the second IP Phone
KEM receives its power, and communicates with the IP Phone, through
the first IP Phone KEM.
If an IP Phone KEM is not responding, and lines or features are configured
on keys 32–79, calls can be directed to those keys which the user cannot
access. This means the IP Phone 2002 or IP Phone 2004 rings but the call
cannot be answered. In such cases, the incoming call receives Call Forward
No Answer (CFNA) treatment.
If only one IP Phone KEM is configured in LD 11, but two IP Phone KEMs
are detected on an IP Phone 2002, the second IP Phone KEM is ignored. An
