Message
Waiting
Indication
The MWI lamps on ONS
sets fail to light when a
message is left even
though the circuit descriptor
is configured to provide
MWI.
Programming incomplete
or incorrect.
1. Verify that the circuit is
assigned an ONS/OPS Circuit
Descriptor that has the
Message Waiting Lamp field on
set to “Yes”

phones have a Class of Service
with the ONS CLASS/CLIP
Message Waiting field set to
“Yes.”

In a network of PBX
platforms, where stations
are programmed to have
voice mailboxes off of a
Message Server or Speech
Server application that is
centrally located at a main
site, the MWI fails to show
the presence of new
messages at the stations.
After the System Option
“Superset Callback
Message Cancel Timer”
expires, MWI is disabled.
This timer is expiring
before the message is
noticed.
