Enable the "
Explicit MWI Subscription
" field by checking the check box.
(Disable this field by unchecking the check box. Default is disabled).
If the IP phone has a message waiting subscription with the Service Provider, a Message Waiting Indicator (MWI) (LED or display icon) tells
the user there is a message on the IP Phone.
4.
If you enable the “
Explicit MWI Subscription
” field, then in the “
Explicit MWI Subscription Period
” field, enter the requested duration, in
seconds, before the MWI subscription times out. The phone re-subscribes to MWI before the subscription period ends. Default is 86400.
5.
Enable the “
MWI for BLA Account
” to enable or disable a BLA configured line to send an MWI SUBSCRIBE message for the BLA account.
Notes:
•
If you change the setting on this parameter, you must reboot the phone for it to take affect.
•
Both the “sip explicit mwi subscription” and “sip mwi for bla account” parameters must be enabled in order for the MWI subscription for
BLA to occur.
•
The MWI re-subscription for the BLA account uses the value set for the "sip explicit mwi subscription period" parameter to re-subscribe.
•
Whether or not the "sip mwi for bla account" parameter is enabled, the priority for displaying MWI does not change.
