# agent_monitor.agi      version 2.14
#
# NOTE! - To use this script you MUST have entries in the System Settings
#         "Custom Dialplan Entry" for this to work. 
#         Read the AGENT_MONITOR.txt document for more information.
#
# This script is designed to allow managers to listen to agent sessions by 
# dialing a phone exten number or user ID number. For this to work, the user ID
# or phone extension must be only digits. If you are using the phone extension,
# then all phone extensions on the system must be unique.
#
# user is prompted for a user ID or phone login then press #
# then the user is forwarded to monitor the active vicidial agent session
#
# ; settings for this script:
# ; 1. USER, PHONE, PLOGIN, REDIRECT or RANDOM, lookup by user id, phone extension or phone login (default is USER)
# ; 2. Y or N, log in api log (default is N)
# ; 3. BARGE or LISTEN, (default is LISTEN)
# ; 4. Prepopulated ID, for use in context by itself
# ; 5. Campaign limits, double-dash-delimited, i.e. "TEST--TEST2", (default is disabled)
# ; 6. Y or N, play user IDs to listen to (default is N)
#
# can be added as an AGI to a Call Menu, or just a direct extension transfer:
#
# ; call menu AGI with options:
#  agent_monitor.agi,USER---N---LISTEN------TEST--TEST2---N
#
# ; or as extension transfer to "up_monitor" context and "s" extension

# CHANGELOG
# 130716-1315 - First build based upon agi-phone_monitor.agi
# 130925-1823 - Added variable filter to prevent DID SQL injection attack
# 191120-0835 - Added RANDOM option, issue #1110
