Message Waiting Indication (MWI)

MWI across multiple Asterisk servers

Depending on how you want to set it up, just use externnotify= and a script that touches the msg<num>.txt file in the user's vm directory on the other boxes. We're using ssh, you may choose to use a different method. It's an immediate MWI notification, and seems to work well.

MWI when modifying mailboxes from outside of asterisk 1.8

after copying/inserting a message (msg0000.gsm msg0000.txt msg0000.WAV msg0000.wav) in the INBOX of a voicemail,
do :

touch /etc/asterisk/voicemail.conf
asterisk -r -x 'reload app_voicemail.so'

it will scans the mailboxes and refresh MWI across all phones.
