# Copyright (C) 2023  Matt Florell <vicidial@gmail.com>    LICENSE: AGPLv2
#
# This script is designed to be used as a "No Agent Call URL" option for an
# In-Group. It will take the lead_id and check to see if it is already in the 
# vicidial_abandon_check_queue table or the vicidial_hopper, and if not, add it
# so that it can be processed by the AST_VDadapt.pl script.
#
# This script is part of the API group and any modifications of data are
# logged to the vicidial_api_log table.
#
# Example of what to put in a No Agent Call URL field for an In-Group:
# (IMPORTANT: user needs to be NOAGENTURL and pass needs to be set to the call_id)
# VARhttp://192.168.1.1/agc/abandon_check_queue.php?lead_id=--A--lead_id--B--&dispo=--A--dispo--B--&user=NOAGENTURL&pass=--A--call_id--B--&log_to_file=1&source=test
# 
# Definable Fields: (other fields should be left as they are)
# - log_to_file -	(0,1) if set to 1, will create a log file in the agc directory
# - source -		1-20 characters, the source of this request
#
# Immediate reject reasons:
# - lead is already in hopper
# - lead is already in vicidial_abandon_check_queue
#
