### 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

# 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
