Automatic Call Distribution: What Is It & 10 Best ACD Systems From 24 Reviewed

It’s no secret that phone calls are a great acquisition channel, with more than decent sales rates. However, it’s one thing to generate inbound phone calls and another thing to ensure that these callers are connected to the best-matching sales representative or business.

Automatic call distribution systems allow you to set all inbound calls on an optimal conversion path while making it smooth and effortless for callers. More so, if you combine ACD with IVR, you can factor in dozens of parameters to distribute or route calls to where they are most likely to generate profits.

Sounds good? 

Then let’s dig deeper into automatic call distribution and explore the 10 best ACD solutions based on our evaluation methodology.

“With phone calls, you’re typically trying to generate a customer that is further down the sales cycle than potentially just a web lead that’s put their data on a website, and you may or may not contact them.” – David Pickard, CEO, Phonexa, during the Unlocking Affiliate Sales with Call Leads, Email & SMS Marketing chat

What Is Automatic Call Distribution?

Automatic call distribution is, in fact, the process of assigning inbound phone calls to a specific sales department, agent, or business based on pre-determined criteria, like the caller’s location, time of day, or the information collected by the IVR system.

Even the simplest ACD system, such as connecting calls from state A to call agent A and calls from state B to call agent B, can have a significant impact on the capacity to process inbound phone calls and monetize them effectively.

Important: It’s crucial that your ACD can integrate with an IVR system and AI Call Agents besides following pre-scripted routing rules. Real-time insights collected by IVR or AI call agents may not only collect user preferences but also alter the underlying business logic.

Internal vs External Automatic Call Distribution

Based on your business goals, you may combine or use one of the following automatic call distribution types:

• Internal distribution (routing): The process of allocating calls between in-house specialists, typically sales and customer service reps. Internal routing favors round-robin and priority-based rules and is driven by regional scope, workforce management, and agent skills.
• External distribution: The process of matching calls with buyers, such as brands or agencies, to generate revenue. External distribution is underpinned by a ping tree, which allows you to deliver calls in real time based on your decision logic, buyer preferences, and lead attributes.

What Does an ACD System Do Besides Routing Phone Calls?

On top of their core functionality, leading automatic call distribution tools also offer:

• Self-service options
• Call forwarding
• Callback automation
• Minimizing call queues
• Fallback routing

A state-of-the-art ACD system ensures the optimal conversion path for every inbound phone call, maximizing your revenues and surpassing user expectations. For example, you can set up your ACD to connect purchase-ready callers immediately to the best-performing available agent. For local campaigns, you might want to connect callers to agents from their locations. And so on.

And if you’re an affiliate network or phone call marketplace, you can use ACD within a ping-post system to connect phone calls to the winning advertisers while ensuring no call goes unsold as long as there’s at least one bid that exceeds the seller’s minimum price for the call.

Can You Benefit from an ACD System as an Affiliate?

Even though an ACD is primarily used by advertisers, affiliate networks, and phone call marketplaces, you can get a massive operational advantage from using it as an affiliate. In fact, using an ACD system allows you to determine which of the advertisers on the other end is going to receive which call, giving you full control over call distribution.

Custom Decision Logic	Create any call distribution or routing rules to maximize conversions and profit
Support for Multiple Verticals	Generate leads for many advertisers in many markets without relying on the routing logic of one network
Resell Unsold Calls	Intelligently resell rejected calls to the highest-paying advertisers

And then you can configure call allocation however you want, factoring in geo filters, price, priority, time of day, and any other data you can track during or before the call. Having an ACD system is especially valuable if you’re driving traffic to advertisers that prohibit certain locations or sources – then you can redistribute these leads to an advertiser that is likely to accept them.

Your Enterprise-Grade Software for Phone Calls and Leads

Whether you generate, buy, or sell inbound phone calls or leads, Phonexa’s enterprise-grade software helps you unlock otherwise unreachable insights into customers while keeping it all organized in one place.

“When phone calls convert 30% faster, spend 28% more, and the retention rate is 28% higher, you don’t need to generate as many as you would web leads. Many people are accustomed to generating hundreds of thousands of web leads, but phone calls are not considered equal. Calls are more valuable, and therefore, you don’t need to generate as many. So businesses are leaving money on the table if they’re just neglecting them altogether.” – David Pickard, CEO, Phonexa, during the Pioneering Pay-Per-Call Excellence webinar

With all essential metrics consolidated within a single dashboard, you always have a bird’s-eye view of your campaign, which can be broken down to a lead-level performance metric if needed. At the same time, most time-consuming routines are automated, so you don’t have to worry about call or lead distribution once you’ve set up your architecture.

Frequently Asked Questions

What is an ACD phone system?

An automatic call distribution (ACD) phone system is a system that can assign inbound phone calls to the best-matching department, agent, or company based on predefined rules. Likewise, depending on the system’s configuration and business needs, an ACD can allocate phone calls based on the caller’s input through the IVR. However, an IVR is not necessarily needed for an ACD system to operate.

What is the best automatic call distribution software?

Phonexa’s ACD system might be your best automatic call distribution software because it synergizes with an IVR system and AI Call Agents, which both make it possible to collect exhaustive insights into the caller and, as a result, distribute or route them accurately.

Which type of call must be immediately delivered to the provider?

Live transfer calls and real-time calls where callers are actively engaging should be immediately transferred to the agent, as long as you want to maximize their conversion potential.

Callers who have to wait in a call queue often lose their conversion potential and may hang up if the waiting time is too long. Therefore, it makes sense to employ an IVR system and AI call agents alongside an ACD system to distribute all inbound calls optimally and minimize wait and hold times.
