#
# agi-phone_monitor.agi version 2.8
#
# 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 or PLOGIN, 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
#
# can be added as an AGI to a Call Menu, or just a direct extension transfer:
#
# ; call menu AGI with options:
# agi-phone_monitor.agi,USER---N---LISTEN---
#
# ; or as extension transfer to "up_monitor_exit" context and "s" extension

#
# CHANGELOG
# 130401-0724 - First build
# 130520-1013 - Added PLOGIN lookup option and no-prompt extension feature
# 130710-1658 - Small change to allow non-hangup between agent calls
# 130925-1824 - Added variable filter to prevent DID SQL injection attack
