There are multiple steps to this...
You will need to configure the card in the System-Cabinets sections, then program the trunks individually (by a range is usually the easiest), then create a new trunk group and add the trunks into it, setup the trunk group to ring a Call Routing Table for day and night (separate ones work best), then program the DDI digits and there destinations... Now that will cover the incoming portion, the outgoing portion will vary depending on if they are accessing the trunk group directly or using ARS.
