# VD_hangup.agi version 0.2
#
# NOTE: This script is only needed on Asterisk 1.2.X and higher systems
# 
# runs when a call hangs up in the second priority behind call_log. This script
# will lookup the uniqueid of the call and/or the callerIDname and update tables
# if it is a VICIDIAL inbound or outbound call that hungup before sent to agent
#
# You need to put lines similar to those below in your extensions.conf file:
# 
# ;VICIDIAL_auto_dialer transfer script:
# exten => h,1,DeadAGI(call_log.agi,${EXTEN})
# exten => h,2,DeadAGI(VD_hangup.agi,PRI-----DEBUG-----${HANGUPCAUSE}-----${DIALSTATUS}-----${DIALEDTIME}-----${ANSWEREDTIME})
# 
# NOTES: 
# - To disable Busy and Disconnect detection change the first field from PRI to NONPRI
# - To disable Debug output to file change the second field from DEBUG to NODEBUG

#
# changes:
# 60203-1218 - fixed calleridname issue with 1.2 tree for custom CID
# 60314-1250 - Altered to allow for ignoring of AGI-defined status
# 60612-1500 - Added option for text log of hangup codes
#            - Added option for PRI hangup code dispositions: BUSY, DISCONNECT
# 60615-1101 - Fixed log updates for CLOSER transfer from fronter calls
