When call volume spikes and every rep is already on the phone, something has to give. Without the right system in place, that usually means callers going to voicemail, reps getting overwhelmed, and potential customers slipping through the cracks.
Automatic call distribution (ACD) solves this by turning a fluctuating inbound call flow into an orderly queue. Calls are held and distributed to available agents based on rules you define, keeping your team working efficiently and your callers from being left in the dark. Here's how it works and why it matters for your business.
An automatic call distribution queue efficiently holds and distributes incoming calls among a group of employees/call agents. While similar to hunt or ring groups, ACD queues offer additional functionality for businesses with high call volume or for those that regularly have multiple calls come in at the same time or within a few minutes of each other.
You can set your queue as the destination of your business’s main phone number or sales number. As calls come into the queue, they are assigned a spot based on the order that they arrive—exactly like grocery shoppers waiting in line to checkout. Calls get distributed to your reps in a 'first in, first out' method. If all of your reps are busy assisting other callers, any new calls that arrive will be held in the ACD queue until a rep becomes available to take another call.
You can configure the queue’s settings so that waiting callers hear music on hold and/or announcements that tell them their place in line or approximate wait time. You can also set the strategy for how calls will be distributed to your reps. Some strategies include:
Reps have to log into the queue in order to receive calls from it. This is typically done by calling the queue’s extension and/or entering its unique PIN number from a desk or softphone. When their workdays are over or they are stepping away from their desks, they simply log out of the queue to become unavailable to take any new calls.
ACD queues help businesses answer incoming calls in an orderly fashion, especially when call volume is high. While ring groups do distribute incoming calls among the members of the group, they don’t offer a great solution for when all group members are busy on calls. With ring groups, any new calls that arrive in the group are sent to the specified failover location, which is usually a voicemail box. If the caller chooses not to leave a message, you’ve just lost a sale or support experience.
ACD queues provide a simple yet effective solution to this by holding callers in line until a rep becomes available. That means more chances to close sales leads and more opportunities to delight your customers by resolving their support issues!
Most UCaaS providers have some advanced features built into their queue product that provide invaluable insights into a business’s sales and customer support efforts:
Use these important pieces of data—unique to your own organization—to make informed decisions for your business.
Whether you're running a busy sales floor or a customer support team, ACD queues do more than just keep calls organized. Here's what they bring to the table:
Shorter wait times, happier callers. Nobody likes being put on hold indefinitely. ACD queues give callers a structured, orderly experience: they know their place in line, they hear an estimated wait time, and they're connected to the next available rep as soon as one is free. That transparency goes a long way toward keeping frustration in check.
No more lost calls. Without a queue, calls that arrive when all reps are busy have nowhere to go but voicemail (and even then, many callers won't leave a message). ACD holds those callers in line rather than bouncing them to a dead end, which means more answered calls, more resolved issues, and more closed deals.
Balanced workloads across your team. ACD distribution strategies like roundrobin and fewest calls routing ensure that no single rep gets buried while others sit idle. Work gets spread more evenly, agents stay more engaged, and your team performs more consistently throughout the day.
Better coaching and performance management. ACD features come with built-in tools that give supervisors real visibility into what's happening on the phones. Call monitoring, whisper coaching, and call recording turn everyday interactions into training opportunities. Use them to help your team get sharper over time.
Data that actually tells you something. Queue reports surface metrics like average wait time, busiest time of day, and total call volume over any given period. Instead of guessing when to staff up or where your call flow is breaking down, you have concrete numbers to act on.
A more professional caller experience. For small and medium-sized businesses especially, ACD queues signal to callers that they've reached an organized, capable operation. On hold messaging, position announcements, and consistent routing all add up to the impression of a competent company.
OnSIP offers ACD queues to our customers as part of our UCaaS platform. Called Enhanced Queues, this business calling feature combines ACD queue functionality with sophisticated monitoring and notification tools.
Enhanced Queues are created in OnSIP’s admin portal. From there, you set up the queue’s features, settings, and ring strategies. You can always make changes to the queue by logging back into the admin portal and adjusting any setting that you wish—changes take effect in real-time.
You can access the Enhanced Queue Dashboard by logging into the OnSIP web app at app.onsip.com or by downloading our desktop app to your computer or laptop. From there, your queue supervisor will get detailed insight into how your queue(s) and call reps are performing. Supervisors will be able to see:
Call monitor, whisper, and barge functions are also available within the Enhanced Queue Dashboard for quick and unobtrusive access to active calls.
Supervisors can also set alerts that will notify them when specific events occur in the queue. Some examples of these events include when the number of waiting callers surpasses a specified amount or when a call that is on hold reaches a specific time limit. Supervisors can be alerted to these events through browser popup notifications or via email.
The Enhanced Queue Dashboard also enables supervisors to generate reports that tabulate the queue’s past stats and trends. Supervisors select the timeframe for the report, as well as the time zone in which to display past calls. The queue report will provide key data points such as:
You can even schedule these reports to be automatically emailed to specific individuals on a daily, weekly, monthly, or quarterly basis.
