# cm_sc_areacode.agi version 2.14
# 
# Designed to work with Call Menus to allow searching of the areacode of the 
# caller ID phone number the customer called in with to be searched within the 
# vicidial_phone_codes table to gather the state, or use the lead_id of the 
# already-established call, then use the settings container ID to gather the 
# state routing parameters to find the destination for that state
#
# If areacode is not found, call will go to the 'D' option in the call menu
# If destination is not found, call will go to the 'C' option in the call menu
# If you are using INGROUP as an option, it will use the 'B' option in the call- 
#      menu and the "Route" must be set to INGROUP and "In-Group" must be set to
#      DYNAMIC_INGROUP_VAR
#
# Flag Options:
# 1- Country code to search the areacode within, default 1
# 2- Length of areacode in digits, default 3
# 3- container_id for settings container with state and routing parameters
#
# example of what to set in the Call Menu:
# Set the prompt to "sip-silence"
# Set the Timeout to 1 second
# Option: "Timeout" Route: "AGI" AGI: "cm_sc_areacode.agi,1---3---east_west"
#
# example of what to put in settings container:
# NOTE: if you want any state non-matches to go to a destination, put that line FIRST
# NOTE: for INGROUP, the 2nd field is the In-Group ID, and the 'B' call menu option needs to have "Route" set to INGROUP and "In-Group" set to DYNAMIC_INGROUP_VAR
#<destination type>|<destination>|<states list separated by spaces>
