# This script is designed purely to send whether the meetme conference has live channels connected and which they are
# This script depends on the server_ip being sent and also needs to have a valid user/pass from the vicidial_users table
# 
# required variables:
#  - $server_ip
#  - $session_name
#  - $user
#  - $pass
# optional variables:
#  - $format - ('text','debug')
#  - $ACTION - ('refresh','register')
#  - $client - ('agc','vdc')
#  - $conf_exten - ('8600011',...)
#  - $exten - ('123test',...)
#  - $auto_dial_level - ('0','1','1.2',...)
#  - $campagentstdisp - ('YES',...)
# 

# changes
# 50509-1054 - First build of script
# 50511-1112 - Added ability to register a conference room
# 50610-1159 - Added NULL check on MySQL results to reduced errors
# 50706-1429 - script changed to not use HTTP login vars, user/pass instead
# 50706-1525 - Added date-time display for vicidial client display
# 50816-1500 - Added random update to vicidial_live_agents table for vdc users
# 51121-1353 - Altered echo statements for several small PHP speed optimizations
# 60410-1424 - Added ability to grab calls-being-placed and agent status
# 60421-1405 - check GET/POST vars lines with isset to not trigger PHP NOTICES
#
