      Patrick,
This is a bash script that externnotify executes
#!/bin/ash
#
# This script is called by Asterisk every time a voice mail is
# left for a subscriber. The CONTEXT, EXTENSION, and VM_COUNT
# are passed by Asterisk.
#
# All we need to do is update a file in /var/spool/asterisk/mwi
# to tell our cron job that we have to send a SIP NOTIFY message
# to a particular UA
#
# This file is referenced in /etc/asterisk/voicemail.conf
#
# NOTE: The $2 argument is passed in to this script in the
#       following form: MAILBOX@DOMAIN
#
#       example: 4075551212@default
#
MWI_DIR=/var/spool/asterisk/mwi/
if [ -n ${2} ] ; then
        if /bin/touch ${MWI_DIR}/${2} ; then
                exit 0
        else
                exit 1
        fi
else
        exit 2
fi
The following is executed in CRON every minute. This script actually
notifies the subscribers by sending NOTIFY messages to SER. Please
note that our asterisk is a modified version that stores mailboxes in
a directory hash, so you can modify this to fit your needs.
#!/bin/sh
# This script send the SIP NOTIFY message to UA. The NOTIFY message
# can either enable or disable the UA message indicator. The script
# looks for any file in $VM_HOME and creates the NOTIFY message
#
# The actual NOTIFY message is sent to the SIP proxy by the sipsak
# utilty. After the message is send we delete the processed file
# from VM_HOME so we don't keep resending the same message. Most
# UAs will periodically send a SUBSCRIBE message to the SIP proxy.
# When this occurs the SIP proxy will place a file in the location
# /var/spool/mwi/delay and a less frequent CRON job will process it.

could you show me an example of the sipsak command for the cisco phone

I can then just make an agi that will call it after vm is left.

Since the SIP UA is registered with SER you'll need to have Asterisk
send a NOTIFY message to the user by means of SER.
So you can send the NOTIFY to SER with a From: header as asterisk
and the <To> / R-URI as the Cisco UA.
FYI, we do this using sipsak to send the NOTIFY to ser. This is
triggered either using the externnotify parameter in the Asterisk
voicemail.conf file and by CRON for periodic MWI updates.

Paul

Hello,
I'm sure this may have been asked but, I just wanted clarify how this
would be accomplished.  I'm looking to have the MWI light on my cisco
phone turn on when a message is left in VM.
Here is my current situation:
sip user -> ser -> asterisk
Best regards,
Patrick b.
