# This script is designed to generate a list of wav audio files to play and then
# insert a record into the vicidial_lead_messages table. This web page should be
# launched from the agent webform or as an IFRAME in a script tab while on a
# call(you can use Get-Call-Launch or the Trigger function to auto-launch a
# webform).
#
# !!! IMPORTANT !!! You must customize this script to your needs, and you must
#                   have the campaign setting for 'Answering Machine Message'
#                   set to 'LTTagent' for this to work.
#
### Example line to put in the campaign WEBFORM field:
# http://127.0.0.1/agc/vdc_LTT_generate.php

# CHANGELOG:
# 200424-2013 - First build of script
