IP Phone Key Expansion Module (KEM)
error message displays to alert the administrator that the hardware
configuration does not match the administered configuration.
If two IP Phone KEMs are configured in LD 11, but only one IP Phone KEM
is responding, the keys on the second IP Phone KEM are available for call
processing but are not accessible to the user. This means that lines and
features on keys 56-79 can cause the IP Phone 2002 to ring, but there is no
way to answer it. An error message displays to alert the administrator that the
hardware configuration does not match the administered configuration.
If only one IP Phone KEM is configured in LD 11, but two IP Phone KEMs
are detected on an IP Phone 2004, the Terminal Proxy Server (TPS) assigns
keys 56–79 to the second IP Phone KEM. An error message displays to alert
the administrator that the hardware configuration does not match the
administered configuration.
If two IP Phone KEMs are configured in LD 11 but only one IP Phone KEM
is responding, the TPS assigns keys 32–79 to the single IP Phone KEM (using
the Shift key functionality). An error message displays to alert the
administrator that the hardware configuration does not match the
administered configuration. When a second IP Phone KEM is detected, the
TPS changes the key assignments to display across both IP Phone KEMs, as
expected.
When a Virtual Office (VO) login occurs from an IP Phone 2002 or
IP Phone 2004 that does not have the same number of IP Phone KEMs
responding as configured on the IP Phone used to log in, call processing may
terminate on a key that is not physically available. In other words, the
IP Phone rings but the call cannot be answered.
During the VO login process, the existence of any IP Phone KEM is verified.
If a mismatch is detected, the login proceeds normally; however, an error
message is generated to alert the administrator of the mismatch.
