# cm_dnc.agi version 2.14
# 
# Designed to work with Cell Menus to allow setting of a number as DNC or NI
# This script is meant as a replacement for the agi-VDADinbound_NI_DNC_CIDlookup.agi
# script. It is designed to work easily in the Call Menu framework, it plays no
# audio itself, and it has more options.
#
# Flag Options:
# 1- run as DNC status or NI status (Default=NI)
# 2- default to insert into the vicidial_dnc table for DNC selections (Default=YES)
# 3- campaign to take dnc settings from(overrides option 2)
# 4- call menu option to send the call to after executing (Default=B)
# 5- if option 3 is used, search for lead in campaign lists, whole system or no lead update(CAMP, SYS, NONE) (Default=SYS)
#
# example of what to put in the AGI entry for a Call Menu AGI route:
# cm_dnc.agi,DNC---YES---TESTCAMP---B---CAMP
