Voice menus allows you to route callers based on keypresses or speech recognition. Callers can listen to a greeting explaining the menu options, and then make a selection.
Queues are used to route callers to a group of agents. Callers who are routed to a queue will wait on hold for an agent to answer based on a series of rules you define in the queue settings.
Schedules define active hours that you can use to control available times for agents and routing features. Schedules are built using days of the week and hours of the day rather than specific calendar dates.
