Message Waiting Indication for the 20DT Handset
Issue 1 August 2006 77
Avaya DECT Mobility Manager
For each 20DT handset the Avaya DECT Mobility Manager handles the message waiting
indication states transiently (is not saved over system reset). If the Avaya system sends an
"MWI-
on ” message to a 20DT handset, the Avaya DECT Mobility Manager has to map this
message into a normal "SETUP” using the voice mail number as calling party number. This call
will be released immediately after it was established. It results to short incoming call indication
from the voice mail party and a new call log entry. The user is able to call back to the voice mail
for retrieving the voice message. This is done by the ADMM when the handset is not in a call
state. Every time a call is released or a DECT location registration happens the scenario above
is repeated until the Avaya system switches off the message indication state.
An entry in the call log can not be removed by the Avaya DECT Mobility Manager. This may
confuse the user in certain situations like the voice mail was already retrieved if using another
phone.
Further on the 20DT handset will be refreshed with the MWI on state after a certain time
interval. This can be administrated for each handset optional.
