# cm_areacode.agi version 2.12
# 
# Designed to work with Call Menus to allow searching of the areacode of the 
# caller ID phone number the customer called in on, to be searched within the 
# vicidial_phone_codes table to gather the state, then search the 
# vicidial_inbound_dids table for that state in the did_carrier_description 
# field and send the call on to the did that matches.
#
# If areacode is not found call will go to the 'D' option in the call menu
# If state DID is not found call will go to the 'C' option in the call menu
#
# Flag Options:
# 1- Country code to search the areacode within, default 1
# 2- Length of areacode in digits, default 3
# 3- DID prefix to filter by in searching for DIDs, default 999
#
# 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_areacode.agi,1---3---999"
