# AST_conf_update_3way.pl version 2.14
#
# This script checks leave 3way vicidial_conferences for participants
# This is a constantly running script that is in the keepalive_ALL script, to
# enable this script in the keepalive, add the --cu3way flag to the
# ADMIN_keepalive_ALL.pl entry in the crontab
#
# NOTE: if you are using this script, then you should set the flag in the other
#      script's crontab entry that does some of these functions:
#      AST_conf_update.pl --no-vc-3way-check

#
# 100811-2119 - First build, based upon AST_conf_update.pl script
# 100928-1506 - Changed from hard-coded 60 minute limit to servers.vicidial_recording_limit
# 130108-1707 - Changes for Asterisk 1.8 compatibility
# 160608-1549 - Added support for AMI version 1.3
# 170222-0939 - Changed to file logging using server settings
# 170921-1814 - Added support for AMI2
# 180420-2301 - Fix for high-volume systems, added varibles to hangup queryCID
# 200413-1356 - Fix for \n\n at the end of PING commands causing errors in AMI
# 231117-2255 - Added AMI version 5 compatibility
# 231118-1110 - Added override option of up to Xtimeout9 for 3WAY_... leave-3way sessions
# 260515-1943 - Added internal logging
