This is an example that assumes the following:
You are in US, New York Timezone. You are using all 4 FXO ports. You want the gateway to auto send the calls to a hunt group (300) from 8:30am-5:00pm during the work week but want them to go to your Auto Attendant (100) at all other times.
The Auto DST-RULES are good through Fall 2016. The example below is marked up for you to be able to adapt it your your environment and is taken from a working example at one of our customer sites.
