Intelligent call routing (ICR) is a business telecom innovation designed to increase efficiency of automated call management and improve the customer experience for callers. ICR is today's state of the art in call routing, offering businesses handling high call volumes incomparable responsiveness, accuracy, and speed. In fact, the extraordinary overall efficiency of ICR has made the best manual call handling, and even digital routing systems not capacitated with artificial intelligence obsolete.

Here is a fairly comprehensive overview of what is involved in intelligent call routing, including a breakdown of general systems functional features and insights into modes of usage, industry best practices, and a look at comparative call center software services and pricing among popular brands of ICR system.

What is Intelligent Call Routing?

Intelligent call routing is a call center technology that captures and places incoming phone calls into a sorting queue and then routes each one to the appropriate group or individual agent. The system determines routing priorities based on logic developed by entries of the system owners' preferred rules and criteria for routing.

The modern intelligent call routing system identifies a caller, enables the caller to select options from menus based on the purpose of the call, and then automatically routes the call to the agent or group designated in the specified routing rules and criteria. When the designated call target is unavailable, the system determines the next best alternate for the call type and caller's specific purpose. The ICR system continues cascading its search through the business's array of targetable agents and groups until it identifies the most appropriate available agent.

ICR has become a business basic for contact centers and other businesses managing large call volumes. Advanced skills-based routing functionality evaluates the candidate targets and routes the call to the agent with the most ideal training, highest proven skill level, and strongest track record of handling the particular call type.

There are numerous additional factors assessed by intelligent call routing systems in selecting among routing options for each call. For example, in addition to agent profiles, the auto-analysis includes call type priority level, group and individual agent utilization levels, a caller's previous reasons for calling, the caller’s account status, other caller-specific and agent- and group-based evaluations, and other routing criteria.


How Does Intelligent Call Routing Work?

Intelligent call routing utilizes several key data types to determine the solution to the problem of where to send each call for the best possible outcome for the caller, the call center agents, and the company:

1. Caller Input — the Interactive Voice Response (IVR) system enables callers to input the essential information needed for proper routing. The information provided this way by the caller during their interaction with the ICR system is the most important information for achieving accurate routing.

Examples of input gathered from callers for the purposes of call routing include account number, phone number, account status, which department they want to reach, the kind of information they want to obtain or outcome they want to accomplish, etc. The ICR uses this information to route the call based on a combination of factors, including the caller's intent and/or the company's priority in dealing with the caller, among others.

The caller can indicate his responses to the ICR system's questions by speaking his answers into the receiver. Alternatively, the caller can press buttons for desired menu selections, in order to execute dual-tone multi-frequency signaling (DTMF). This data gathering allows the system to determine the caller's intent as well as any restrictions the company may have for the caller, and then route the call accordingly.

2. Current Caller Data — electronic data gathering features of ICR software include Automatic Number Identification (ANI), which automatically identifies telephone number from which the call is originated. The data collection tools in the ICR system also include Dialed Number Identification Service (DNIS), which is designed to determine to which department or individual the caller should be directed.

3. Historical Caller Data — upon identifying the caller, ICR systems automatically draw details about the caller from the company's database. Such details can include the customer's history of purchases, contracts, service programs, account status, customer support history, and certain personal information that can help ensure the caller's intent is interpreted correctly.

After the ICR system collects the necessary data, it matches the data to the criteria and rules the business has set for sending calls to specific departments, groups, individuals, or recordings of messages on various topics that have been deemed relevant to the caller. For example, if a caller has already called at least once in the same day about an unresolved billing dispute, the ICR system may connect the caller to an available billing support agent who is identified in the system as having the highest level of skill in handling such issues.

Core tools of intelligent call routing systems perform functions that:

  • Gather and interpret current and historical caller-specific data and input from the caller
  • Route the call to the appropriate group or individual agent with the skills best suited to provide an effective solution for the caller
  • Direct the caller to the nearest of the company's locations of operation, if resolving the customer's problem necessitates going to an actual store, office, or other physical site
  • Connect a caller with the same agent they previously spoke with, to deliver support service continuity
  • Provide call center agents with information collected through the ICR system about a callers’ background, enabling agents to generate the highest possible level of customer satisfaction by providing the best possible customer experience as well as the smoothest and best employee experience for agents
  • Perform data analytics to enable system-users' understanding of, and more efficient management of call volumes, wait times, call duration, resolution times, FAQs, agent and group performance tracking metrics, and other key factors in the call handling operation's performance
  • Integrate with other information systems, such as HR training databases, call center employee scheduling programs and others, to help manage call volume balance across the inbound call center or operations departments of the ICR-enabled company


Pros and Cons of Intelligent Call Routing

Intelligent call routing is at the leading edge of business systems innovations for companies that need to maximize efficiency of high-volume telecommunications. Whatever the size and nature of your business, if your communications systems are frequently over-run and you need increased call-handling capacity, ICR technology offers today's most cost-effective and functionally streamlined solution.

Of course, as with any approach to business solutions, it's important to weigh all the considerations in order to make the best decision for your company's unique needs. There can be both pros and cons in migrating to an intelligent call routing system.



  • Calling a call center with ICR significantly increases the likelihood that the caller will be connected with the agent best-suited to help fully accomplish his/her purpose of the call and deliver the best customer experience in the process
  • Intelligent call routing systems substantially reduce wasted payroll time by eliminating the high frequency of cases in which callers are forced to repeat their explanations of their problem to multiple agents before finally being connected to the person who can actually solve their problem
  • Customer experience is greatly improved by reducing the amount of the caller's valuable time that is wasted being transferred from one department to another and repeating the details of their reason(s) for calling to multiple agents before finally reaching the right person for the kind of help they need
  • Customer service costs are reduced by having an auto-attendant system managing call routing in high volume call centers and other business operating environments
  • Information gathered through the ICR data gathering process enables greater insights into customers' broader needs and interests, as they relate to the business's products and services. This advantage increases agents' abilities to add value to their service interactions with callers, and thereby build relationships that promote the brand
  • Information provided for agents by ICR systems, such as the caller's personal record of dealing with customer service, account activity, payment history, and other useful details empower the agent with knowledge that helps reduce potential frustrations for both customer and agent. This promotes employee satisfaction with his/her call center role and with the company



  • If data quality problems are significant in a business, an effective ICR system cannot be successful. At minimum, agent and group skill sets and IDs and customer account identifications all need to be as complete as possible. Shared or missing IDs can make attempting to navigate an ICR system a miserable and fruitless experience for callers and agents alike. So, it's imperative to clean up issues in relevant data prior to migrating to an ICR system
  • ICR platform integrations can be very time consuming and difficult to perform. Working with IT professionals who are well-experienced in needs analysis for such migrations and in implementation is necessary for identifying and resolving impediments to smooth integration before embarking on your transition to an ICR system
  • It is easy to become over-reliant on ICR capabilities and allow focus to drift away from other essentials for successful call management. For example, although artificially intelligent call routing improves performance reflected in many important business metrics, it can effectively mask deficiencies in management, training, service culture, and other critical areas of operational structure. Strengthening focus on objectives and goals in these areas after your ICR systems roll out is key


Does My Call Center Need Intelligent Routing?

There are some red flags that mark the need for an ICR system in a business. In busy business operations that are handling high volumes of inbound calls, callers are likely to report one or all of these common problems when attempting to communicate issues to customer service agents:

  1. Excessive time on hold
  2. Multiple department transfers
  3. Difficulty identifying the most qualified agent for handling the specific issue
  4. Excessive time spent trying to make the problem clearly understood

Under such circumstances for callers as those described above, companies very often lose track of the caller's intent, and customer dissatisfaction rates resulting from frustrations, stress, and unresolved issues grows.

If your customers are frequently experiencing one or more of the above four problems or others when engaging with your business communications system, they, and your team, and your investors may all benefit from implementation of an updated artificially intelligent call routing system.

Providing a modern call routing system can correct severe systemic inefficiencies, such as gross imbalances in agent and group utilization for call handling. An ICR system can also help significantly increase your first call resolution rates while simultaneously reducing your average call time. ICR systems include many functional features that enable and assist agents in maximizing productivity per call, such as:

  • Agent access to customer purchasing and billing account information
  • Agent access to history of customer service interactions
  • Note-writing function for adding comments to a caller's customer service file
  • Conferencing with an SME, to increase productivity of a call
  • Call-back scheduling feature
  • Supervisor's monitoring and in-call agent coaching feature
  • Call joining feature, to help ensure a productive call
  • Chat routing and chat management tool sets
  • Insights from first call resolutions and agents with best resolution rates

Naturally, major investment in hiring and training top talent call center agents is a waste, if current and prospective customers are unable to communicate with the right agents and obtain the customer service solutions they need when they call your company. ICR systems have enabled modern companies to leap beyond those old common service problems and focus fully on premium individualized service solutions.

Best Practices for Migration to an ICR System

Migrating from a legacy automatic call distribution (ACD) system to an artificially intelligent routing (ICR) platform is not a process of replicating a similar technological or operational solution. Thinking in terms of maintaining the legacy system functionality to ensure a seamless service transition can be expected to lead to unnecessary difficulties, confusion, and frustrations for callers and call operations management and agents. The best approach is to take the opportunity to upgrade your existing customer experience tools and embrace the process of standing up an optimal system.

For most efficient and minimally painful implementation, employ these fundamental ICR platform migration best practices:

  • First, identify your business goals for the ICR system, and for the improvements to customer experience and agent experience you want to achieve
  • Segment your customer base, and decide on an appropriate strategy for providing service to each segment. For example, determine what service inclusions you will establish for the higher- value customers, lower-value customers, and for your middle market
  • Strategize handling processes for all your communications channels to be networked across your integrated ICR platform, instead of managing these as vertical channels, in order to enable a seamless overall customer experience with your brand
  • Assess the hard and soft skill levels across your call operations workforce. Prioritize the skill sets and proficiency levels necessary to facilitate the quality of customer journeys needed to grow and secure your brand. Identify skills gaps, missing or overpopulated agent roles, training needs, and other areas of needed change in your call operations
  • Prioritize delivery of the optimum customer experience, and match the ideal agent skills to enable targeting of your most appropriate available resources for each caller. Next, prioritize the best alternative treatment for the same caller profile, and establish desired alternate targets for instances in which conditions for the first tier targeting are not met (due to unavailability of the first-tier agent or group)

Generally, call routing priorities should be broadly configured to cause:

  • The top 10 to 20 percent of the highest-value caller interactions are met by the best skilled agent available the majority of the time
  • Between 60 to 80 percent of all customer interactions through the call operations center have a good customer experience, with minimally increased wait times, and minimally reduced quality service by less skilled agents for a large percentage of your call operations time
  • The most costly caller interactions, including unusual issues and overflow volume draw from the lowest 5 to 20 percent of your service resources, consume a low percentage of call operations time, and receive sufficient service the majority of the time. Depending on your call operations team performance levels, this may translate into increased training and coaching needs for your lowest skilled agents


Should I Use an Intelligent Call Routing System?

Artificially intelligent call routing systems can improve the customer experience and the call operations employee experience while reducing costs of customer support at the same time. A well-designed and properly implemented ICR system can be expected to handle the great majority of your call routing requirement dynamically, seamlessly and expeditiously.

Appropriately prioritizing each communications channel, caller profile, call type, and agent skills type and level — and ensuring clean data sources — will enable configuring your ICR system logic to facilitate the most consistently productive possible interactions between callers and agents. Taking time to ensure that your system set up generates the most appropriate match of callers to resources is the secret to auto-routing calls to the correct queue and boosting first call resolution ratios, customer satisfaction and employee satisfaction rates.

Before and after implementation of your ICR platform, closely monitor call operations performance metrics, to understand the new system's actual extent of business impact. Keep in mind that seasonal factors, variable market conditions, and the typical ongoing training and process improvements in call operations facilities can make ICR systems performance differentials too difficult to measure precisely.

Nevertheless, with a well-configured and implemented artificially intelligent call routing system, the business benefits inevitably become obvious over time. If that is not your experience as an ICR platform owner or administrator or call operations manager, it may become necessary to conduct an audit of the ICR programming and installation, to understand what corrections are necessary for more ideal routing.
