# AST_vm_update.pl version 2.14
#
# DESCRIPTION:
# uses the Asterisk Manager interface to update the count of voicemail messages 
# for each mailbox (in the phone and vicidial_voicemail tables) in the voicemail
# table list is used by client apps for voicemail notification
#
# If this script is run ever minute there is a theoretical limit of 
# 1200 mailboxes that it can check due to the wait interval. If you have 
# more than this either change the cron when this script is run or change the 
# wait interval below
#
# NOTE: THIS SHOULD ONLY BE RUN ON THE DESIGNATED VOICEMAIL SERVER IN A CLUSTER!

# 50823-1422 - Added database server variable definitions lookup
# 50823-1452 - Added commandline arguments for debug at runtime
# 60717-1204 - Changed to DBI by Marin Blu
# 60715-2301 - Changed to use /etc/astguiclient.conf for configs
# 90919-1739 - Added other voicemail checking from vicidial_voicemail table
# 100625-1220 - Added waitfors after logout to fix broken pipe errors in asterisk <MikeC>
# 130108-1713 - Changes for Asterisk 1.8 compatibility
# 141124-1019 - Changed to only allow running on designated voicemail server, run for all mailboxes
# 150610-1200 - Added support for AMI version 1.3
# 170609-0936 - Added support for Asterisk 13
# 200413-1356 - Fix for \n\n at the end of PING commands causing errors in AMI
