#
# This script is designed purely to send whether the client channel is live and to what channel it is connected
# 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')
#  - $exten - ('cc101','testphone','49-1','1234','913125551212',...)
#  - $protocol - ('SIP','Zap','IAX2',...)
# 
#
# changes
# 50404-1249 - First build of script
# 50406-1402 - added connected trunk lookup
# 50428-1452 - added live_inbound check for exten on 2nd line of output
# 50503-1233 - added session_name checking for extra security
# 50524-1429 - added parked calls count
# 50610-1204 - Added NULL check on MySQL results to reduced errors
# 50711-1204 - removed HTTP authentication in favor of user/pass vars
# 60103-1541 - added favorite extens status display
# 60421-1359 - check GET/POST vars lines with isset to not trigger PHP NOTICES
# 60619-1203 - Added variable filters to close security holes for login form
# 60825-1029 - Fixed translation variable issue ChannelA
# 90508-0727 - Changed to PHP long tags
# 130328-0027 - Converted ereg to preg functions
# 130603-2214 - Added login lockout for 15 minutes after 10 failed logins, and other security fixes
