### This script is designed purely to check whether the voicemail box on the server defined has new and old messages
### 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')
###  - $vmail_box - ('101','1234',...)
### 

# changes
# 50422-1147 - First build of script
# 50503-1241 - added session_name checking for extra security
# 50711-1201 - removed HTTP authentication in favor of user/pass vars
# 60421-1147 - check GET/POST vars lines with isset to not trigger PHP NOTICES
# 60619-1204 - Added variable filters to close security holes for login form
#
