An automated call distribution system, commonly known as automatic call distributor or automatic call dispatcher (ACD), is a telephony device that answers and distributes incoming calls to a specific group of terminals or agents within an organization. ACDs direct calls based on parameters that may include the caller's telephone number, the number they dialed, the time of day or a response to an automated voice prompt. Advanced ACD systems may use digital technologies such as computer telephony integration (CTI), computer-supported telecommunications applications (CSTA) or IVR as input to determine the route to a person or voice announcement that will serve the caller. Experts claim that "the invention of ACD technology made the concept of a call centre possible." [1] [2]
A Private Branch Exchange (PBX) is a telephone exchange device that acts as a switchboard to route phone calls within an organisation. This technology developed into Automated Call Distribution systems using computer technology to automatically connect incoming calls to recipients based on programmable logic. [3] [4]
Although ACDs appeared in the 1950s, one of the first large and separate ACDs was a modified 5XB switch used by the New York Telephone Company in the early 1970s to distribute calls among hundreds of 4-1-1 information operators. Robert Hirvela developed and received a patent for technology that was used to create the Rockwell Galaxy Automatic Call Distributor, which was used by Continental Airlines for more than 20 years. Since then, ACDs have integrated incoming call management and voice messaging software into its capabilities. [5] [6]
ACD systems route incoming calls to people according to defined rules that may include, for example, the time of day, the day of the week, the geographic location of the caller and the availability of people to respond. The rules should aim to route the call to a person qualified to address the caller's needs. Routing can use caller ID, automatic number identification, interactive voice response or dialed number identification services to determine how calls are handled. ACD systems are often found in offices that handle large volumes of incoming phone calls from callers who require assistance at the earliest opportunity, but have no need to talk to a specific person: e.g., customer service representatives or emergency services dispatch centers.
There are several contact routing strategies that can be set up within an algorithm based on a company's needs. Skills-based routing is determined by an operator's knowledge to handle a caller's inquiry. Virtual contact centers can also be used to aggregate the skill sets of agents to help multiple vendors, where all real-time and statistical information can be shared amongst the contact center sites. An additional function for these external routing applications is to enable Computer telephony integration (CTI), which improves efficiency for call center agents by matching incoming phone calls with relevant data via screen pop.

Methods for distributing incoming calls from a queue include
A call centre or call center is a managed capability that can be centralised or remote that is used for receiving or transmitting a large volume of enquiries by telephone. An inbound call centre is operated by a company to administer incoming product or service support or information inquiries from consumers. Outbound call centres are usually operated for sales purposes such as telemarketing, for solicitation of charitable or political donations, debt collection, market research, emergency notifications, and urgent/critical needs blood banks. A contact centre is a further extension of call centres telephony based capabilities, administers centralised handling of individual communications, including letters, faxes, live support software, social media, instant message, and email.
Dual-tone multi-frequency signaling (DTMF) is a telecommunication signaling system using the voice-frequency band over telephone lines between telephone equipment and other communications devices and switching centers. DTMF was first developed in the Bell System in the United States, and became known under the trademark Touch-Tone for use in push-button telephones supplied to telephone customers, starting in 1963. DTMF is standardized as ITU-T Recommendation Q.23. It is also known in the UK as MF4.
Interactive voice response (IVR) is a technology that allows telephone users to interact with a computer-operated telephone system through the use of voice and DTMF tones input with a keypad. In telephony, IVR allows customers to interact with a company's host system via a telephone keypad or by speech recognition, after which services can be inquired about through the IVR dialogue. IVR systems can respond with pre-recorded or dynamically generated audio to further direct users on how to proceed. IVR systems deployed in the network are sized to handle large call volumes and also used for outbound calling as IVR systems are more intelligent than many predictive dialer systems.
Computer telephony integration, also called computer–telephone integration or CTI, is a common name for any technology that allows interactions on a telephone and a computer to be coordinated. The term is predominantly used to describe desktop-based interaction for helping users be more efficient, though it can also refer to server-based functionality such as automatic call routing.
The Automatic Voice Network was a worldwide American military telephone system. The system was built starting in 1963, based on the Army's existing Switch Communications Automated Network (SCAN) system.
An answering machine, answerphone, or message machine, also known as telephone messaging machine in the UK and some Commonwealth countries, ansaphone or ansafone, or telephone answering device (TAD), is used for answering telephone calls and recording callers' messages.
A voicemail system is a computer-based system that allows callers to leave a recorded message when the recipient has been unable or unwilling to answer the phone. Calls may be diverted to voicemail manually or automatically. The caller is prompted to leave a message and the recipient can retrieve the message at a later time.
In telephony, an automated attendant allows callers to be automatically transferred to an extension without the intervention of an operator/receptionist. Many AAs will also offer a simple menu system. An auto attendant may also allow a caller to reach a live operator by dialing a number, usually "0". Typically the auto attendant is included in a business's phone system such as a PBX, but some services allow businesses to use an AA without such a system. Modern AA services can route calls to mobile phones, VoIP virtual phones, other AAs/IVRs, or other locations using traditional land-line phones or voice message machines.
A business telephone system is a telephone system typically used in business environments, encompassing the range of technology from the key telephone system (KTS) to the private branch exchange (PBX).
In telephony, a zip tone is a call-progress tone which indicates a new incoming call is either connecting or waiting depending on the application. Unlike a ringtone, which alerts those near a telephone to answer it, a zip tone alerts someone already on the line—for example a telephone operator, call center agent, or telephone subscriber with call waiting service—that action is needed for an incoming call such as pressing a button or reciting a phrase. This way of offering an incoming call to an available call center agent is also referred to as 'call forcing' or 'forced calling'.
Amtelco is a family-owned contact center software company devoted to providing fast, secure, and reliable communication solutions for healthcare, contact centers, and other organizations looking for immediate and reliable connections. Founded in 1976, Amtelco originally began as a manufacturer of telecommunications equipment for telephone answering services and call center systems, but it has since gone from a mom-and-pop shop to a trusted leader in the telecommunications software industry. Amtelco employs more than 120 people and has customers located in all 50 U.S. states and over 20 countries. Amtelco holds more than 30 U.S. patents for telephony software, data handling methodologies, and telephone switching devices.
Screen pop is a call centre term that refers to the feature of a computer telephony integration (CTI) which automatically displays customer information via a window or dialog box on an agent's computer upon answering a customer's call.
PhoneValet Message Center is a discontinued Mac-based multi-line computer-telephony software application from Parliant Corporation. The application provided computer-telephony functionality including voicemail, call recording, and the maintenance of a call history. The system is a combination of software and hardware. PhoneValet was awarded an Eddy award for 2006.
Virtual queue is a concept used in both inbound call centers and other businesses to improve wait times for users. 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. Virtual queue systems allow callers to receive callbacks instead of waiting in an ACD queue.
Skills-based routing (SBR), or skills-based call routing, is a call-assignment strategy used in call centres to assign incoming calls to the most suitable agent, instead of simply choosing the next available agent. It is an enhancement to the automatic call distributor (ACD) systems found in most call centres. The need for skills-based routing has arisen as call centres have become larger and dealt with a wider variety of call types.
Toll-free telephone numbers in the North American Numbering Plan have the area code prefix 800, 833, 844, 855, 866, 877, and 888. Additionally, area codes 822, 880 through 887, and 889 are reserved for toll-free use in the future. 811 is excluded because it is a special dialing code in the group NXX for various other purposes.
Call management is the process of designing and implementing inbound telephone call parameters, which govern the routing of these calls through a network. The process is most prominently utilized by corporations and the call centre industry and has its highest effectiveness when call logging software tools are used. Calls are routed according to the set up of calling features within the given system such as Call queues, IVR menus, Hunt groups and Recorded announcements. Call features provide a customised experience for the caller and maximize the efficiency of inbound call handling. Call management parameters can specify how calls are distributed according to an operator's skill level in relation to a call, the time and/or date of a call, the location of the caller or through automatic routing processes.
In computer telephony an automatic dialler is a computer system that makes outgoing calls from a call centre to customers from call agents based upon a loaded list of contacts. Whereas automatic call distribution (ACD) distributes inbound calls to a call centre amongst its agents, an auto dialler makes outbound calls and comes in several forms. Auto diallers are responsible for providing management information to call centre operators, including how many outbound calls each agent has handled. In more sophisticated computer telephony systems, a single system handles both ACD of inbound calls and dialling of outbound calls, allowing agents to be switched between the two as traffic volumes require.
Voice-based marketing automation (VBMA) refers to software platforms designed for marketing, sales, and support departments to measure, manage, and automate their phone conversations. Marketing departments, sales teams, and support agents use VBMA to initiate, manage, monitor, track, route, record, and report on sales and support phone conversations.
