# AST_CRON_mix_recordings.pl
# runs every 5 minutes and mixes the call recordings in the monitor together
# and puts the resulting ALL file into the DONE directory in the "monitor" dir
# 
# soxmix is REQUIRED to use this script, soxmix is available only as part of 
# the sox audio package, and only in newer versions. Make sure you have soxmix
# installed properly and in your path
# 
# put an entry into the cron of of your asterisk machine to run this script 
# every 5 minutes or however often you desire
#
# make sure that the following directories exist:
# /var/spool/asterisk/monitor		# default Asterisk recording directory
# /var/spool/asterisk/monitor/DONE	# where the combined files are put
# /var/spool/asterisk/monitor/ORIG	# where the original in/out files are put
# 
# This program assumes that recordings are saved as .wav
# should be easy to change this code if you use .gsm instead
# 
# This program also sends the ALL combined file to an FTP server for archival
# purposes, you can comment out the Net::Ping and Net::FTP lines as well as the
# file transfer section of the code to deactivate remote copying of the
# recording files

# 51021-1058 - Added quotes around CLI executed commands
# 51122-1458 - Added soxmix binary path check
# 60318-0921 - Added ability to mix gsm audio files
# 60807-1308 - Modified to use /etc/astguiclient.conf for settings 
# 71004-1124 - Changed to not move ORIG recordings if FTP server does not Ping
# 71005-0049 - Altered script to use astguiclient.conf for settings
