Call Queue and Automatic Call Distribution (ACD)

waiting in call queue

VIRTUAL QUEUING IS A CONCEPT USED IN INBOUND CALL CENTERS. CALL CENTERS USE AN AUTOMATIC CALL DISTRIBUTOR (ACD) TO DISTRIBUTE INCOMING CALLS TO SPECIFIC RESOURCES (AGENTS) IN THE CENTER. ACDS HOLD QUEUED CALLS IN FIRST IN, FIRST OUT ORDER UNTIL AGENTS BECOME AVAILABLE. FROM THE CALLER’S PERSPECTIVE, WITHOUT VIRTUAL QUEUING THEY HAVE ONLY TWO CHOICES: WAIT UNTIL AN AGENT RESOURCE BECOMES AVAILABLE, OR ABANDON (HANG UP) AND TRY AGAIN LATER. FROM THE CALL CENTER’S PERSPECTIVE, A LONG QUEUE RESULTS IN MANY ABANDONED CALLS, REPEAT ATTEMPTS, AND CUSTOMER DISSATISFACTION.

WHAT DO CALL QUEUES DO?

Call queues are used to route calls in a first-in/first-out manner to the appropriate agent. These agents can be logged into the system via an extension. Call Queues are commonly used with an ACD, where the callers hear an announcement similar to “thank you for calling, all available agents are busy, please hold for the next available agent, or press 0 to leave a message”. When an agent becomes available the call is routed to that agent. There are several routing options for call queues including: ring all, round-robin, least recent, fewest calls and random. These routing options ensure you fairly distribute calls across all agents in a queue. Automatic Call Distribution (ACD) is used to route calls in a call center environment to the appropriate agents, based on factors such as time availability, behavior, and priority levels.

 

WHAT DOES AN ACD QUEUE DO?

An Automatic Call Distribution Queue (ACD Queue) is one of those oddly worded terms that manages to make its way into almost any industry, especially technology-based industries. While it sounds odd, it gets simple when you can understand it in simple terms – it’s a system in the cloud that allows customers to be put on hold until someone in the call queue can take their call. It’s referred to as a queue because it holds the callers’ place in line, each being answered in the order they were received. Automatic distribution is because nobody has to manually connect the busy line, so as soon as there’s an available phone line the caller is automatically connected to the next agent.

Let's Start a Conversation

But simplifying the ACD queue like that doesn’t really give full credit to what a properly built system is capable of, and how much effort goes into the little details. A robust ACD queue is critical for any office of more than three people. First, the system has to know which extensions can take which kind of call – so that if someone presses ‘one’ for sales, they actually get to the sales department. Call queues at Carolina Digital Phone can have music while in the call queue or a recorded message the caller can listen to while waiting. If the call queue has too many callers for the regular sales team to handle, the administrator of the system can decide whether additional calls go to voicemail, are routed to another call center, or keep waiting until someone is available. Who gets calls in which order when there’s not a backlog of people waiting is also a standard option, so that the system will either balance the workload evenly or prioritize who gets calls based on the owner’s preferences and needs. All of these options are standard in Carolina Digital Phone’s ACD call queue at no additional cost.

 

There are, however, a great many companies that say they provide a ‘queuing service’ that do not actually provide ACD queues. These simple replacements are referred to in the industry as ‘hunt groups’, because all they do is take a list of extensions and attempt to call each one until it gets an answer or gives up. The quality of these hunt groups varies wildly. Some will simply ring through each extension from the one listed first until the last until someone picks up or is transferred to voicemail. This not only means that the first person is always busy while the last is rarely busy, but it also means that the caller has to wait on hold before being connected while busy phones are being called. A real ACD call queue would be able to tell which lines are in use in advance, thus cutting down on wait time dramatically.

 

Our call queue has a number of distribution options:

Priority/Penalty Weights

Finally, you can assign priority and/penalty weights to agents in your call queue to distribute calls to agents in a weighted method. If any of these call queue options are not correct for you, for a small setup fee we can write custom scripts to fix your exact needs.
 

High Quality ACD Queuing

In general, if you need high quality ACD call queuing service, you can depend on Carolina Digital Phone to provide the service that will fit your needs, no other cloud call queue comes even remotely close to the features we offer.

We have been using Carolina Digital for close to 7 years now and they have been fantastic this entire time! I can't remember a single time our phones have been down to anything on their end and their service is exceptional. I also love their billing because it is always the same. No mystery fees that sneak up on you.....you know how you were use to paying the same monthly bill for so long and then all of a sudden it is much higher and you've changed nothing to your phone system. That doesn't happen with these guys! I also need to mention that Randy and Eric in support are amazing and our account manager, Chris Villa is super awesome too! Keep up the great work guys!

Carolina Digital was so helpful to us when we had to transition to a virtual office. The service is great and the people are so helpful. The virtual phone system works better than what we were using in our office and they have a great online dashboard that is very easy to use. We are sticking with them even when we go back to a real office.

Awesome service. Competitive pricing, great local support, solid phones that you own, online dashboard, no constant upsells (this is huge IMO, almost every other online service nowadays bombards you with annoying upsells), no junk fees, customizable, local business, the list can go on. Shoutout to the Man in Green, Randy, and Germaine! Incredible guys over there.
