# Copyright (C) 2026  Matt Florell <vicidial@gmail.com>    LICENSE: AGPLv2
#
# This script is designed to be used in the "Dispo URL" field of a campaign
# or in-group. It adds the phone_number of the call to a designated inbound 
# Filter Phone Group
#
# 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 the Dispo URL field:
# VARhttp://192.168.1.1/agc/dispo_add_FPG.php?phone_number=--A--dialed_number--B--&lead_id=--A--lead_id--B--&dispo=--A--dispo--B--&user=--A--user--B--&pass=--A--pass--B--&FPG_id=BLOCKSALE&sale_status=SALE---SSALE---XSALE&log_to_file=1
# 
# 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
# - sale_status -	(SALE---XSALE) a triple-dash "---" delimited list of the statuses that are to be moved
# - FPG_id -		(999,etc...) the Filter Phone Group ID that you want the phone number to be inserted into
#
# CHANGES
# 150724-1657 - First Build
# 170526-2305 - Added additional variable filtering
# 210615-1039 - Default security fixes, CVE-2021-28854
