Callers can reach a hunt group or queue in multiple ways:
Extension: Assign a unique extension to the hunt group or queue configuration.
An extension allows users to transfer calls directly to the group, bypassing the auto-attendant. The extension can also be set as the Night Forwarding destination for hunt groups and queues, and callers can dial the extension from a Menu route in an auto-attendant if extension dialing is enabled.
Phone Number: Assign a phone number destination to the group.
The phone number can be set as the destination for Forward to Phone Number routes in an auto-attendant, Night Forwarding in hunt groups and queues, or simply as a failover destination for users.
Auto-Attendant: Add a Hunt Group or Queue route to the auto-attendant, then assign a group to the route.
The group assigned to the route can be hot-swapped at any time, even while the auto-attendant is live and processing calls, allowing you to quickly update the call flow at a moment's notice. For example, if power goes out at the London office and the New York office needs to take over their call load temporarily, you can open the auto-attendant editor and switch the queue from one team to the other. Changes are saved immediately.
