#!/usr/bin/perl
#
# agi-DID_route.agi version 2.6
# 
# 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 in
# the context for where incoming calls go from your trunks (for example, the
# trunkinbound context which is present in the default dialplan):
#
#[trunkinbound]
# ;inbound DID catch-all:
#exten => _X.,1,AGI(agi-DID_route.agi)
