VM_COUNT=$3
ASTCMD=”asterisk -rx”
if [ $EXTEN -eq 1000 ];then
if [[ $VM_COUNT = “0” ]];then
logger -t groupmwi “Switch OFF Group mailbox 1 message waiting”
$ASTCMD “devstate change Custom:groupmwi NOT_INUSE”

3. Press the ESC to quit the edit mode and :wq to save the script in vi editor.

4. Change the permission of this script groupmwi.sh using the command chmod 777 /ysdisk/support/tmp/groupmwi.sh

Step 2 Customize the voicemail.conf

1.Create the custom configuration file voicemail_custom.conf in the directory /ysdisk/support/customcfg. By command: vi /ysdisk/support/customcfg/voicemail_custom.conf

2. Press i and input the content below:

[general]
externnotify=/ysdisk/support/tmp/groupmwi.sh

3. Press ESC and :wq to save the changes

It looks like this,

[Local_Default_CallingRules]
include = sla_stations
include = reset_followme
include = enable_followme_always
include = disable_followme_always
include = enable_followme_noanswer
include = disable_followme_noanswer
include = enable_followme_busy
include = disable_followme_busy
