# agi-VDADlisten_DTMF.agi version 2.0.5   *DBI-version*
# 
# To be initiated by an agent so during a call. Agent will click a PIN NUMBER
# link on a web form webpage that will Originate a new call to this script
#
# This script plays a beep and waits for entry of 4 digits then inserts record
#
# ***** THIS SCRIPT ONLY WORKS WITH A CROSSOVER T1 CABLE FROM ONE T1 PORT *****
# ***** TO ANOTHER T1 PORT WHETHER ON THE SAME SERVER OR DIFFERENT ONE    *****
#
# IN THE CAMPAIGN OR IN-GROUP NUMBER PRESET FIELD:
# AXFER83009
#
# ON THE SERVER ORIGINATING THE CALL:
#;outbound DTMF VICIDIAL calls:
#exten => _983009.,1,AGI(call_log.agi,${EXTEN})
#exten => _983009.,2,Dial(${TRUNKY}/${EXTEN:1},60)
#exten => _983009.,3,Hangup
#
# ON THE SERVER THAT HAS THIS SCRIPT:
#;inbound DTMF VICIDIAL calls:
#exten => _83009.,1,AGI(agi-VDADlisten_DTMF.agi,${EXTEN})

# changes:
# 60206-1434 first build
# 60207-1205 - added database records entries/modifications
# 60207-1507 - added ability to send AMs to campaign-defined message to leave
# 60731-1536 - changed to use DBI-DBD::mysql
#            - changed to use /etc/astguiclient.conf for configs
# 60817-1113 - added output options check from database
# 70806-1619 - added HeavyDTMF check and filter
