When you log in, you will be at the group level. Call flow settings are typically found in Services. Press Services on the left-hand side to go to the Services section. Hunt Groups are found in the Basic column.
On the Hunt Group Page, you will immediately see a list of all group-level hunt groups you have. It is highly likely you had one or more in place at the time of activation. To view and edit one of your existing Hunt Groups, press the Edit link to get more information about this group.
When editing the Hunt Group, the Addresses link lets you manage the incoming number and internal extension.
The drop-down list shows the available direct inward dialing numbers available for this service. Select one if you want callers to directly dial to the hunt group.
Place a two to five digit extension for this hunt group here, which will make the hunt group accessible internally via transfer or auto attendant.
When satisfied with your adjustments, save them with OK and return to the previous screen.
