#!/usr/bin/perl
#
# agi-DID_route.agi version 2.2.0
# 
# runs when a call comes into an inbound context on a trunk. This script will 
# send the calls to various places depending on the settings for each DID.
# 
#
# You need to put a line similar to this below in your extensions.conf file:
# ;inbound DID catch-all:
#exten => _X.,1,AGI(agi-DID_route.agi)

# 90117-0756 - Added vicidial_did_log logging to database
# 90214-0217 - Added 'default' did option, to send all non-matching calls to, enforced did_active setting
# 90507-1145 - Added CALLMENU option
# 90825-2252 - Changed PHONE to route using dialplan number
