There are five types of call queues in business phone systems.
Round robinThe round robin call queue sends the caller to the agent who has been idle the longest. That’s why this type of call queue is also known as longest idle.
Ring allIn ring all phone queues, an incoming call is routed to all available agents simultaneously.
Linear huntIn the linear hunt phone queue, the call goes to available agents in a predefined order, which can be chosen when agents are marked as available in the business phone system.
Linear cascadeIn this type of phone queue, the calls go to groups of agents in a predefined order. The order of the groups of agents can be chosen when agents are designed as available in the business VoIP software.
Call parkIn this type of queue, the caller is put on hold until an agent picks up the call.
