This interactive voice response (IVR) diagram sample illustrates the IVR services.
"IVR systems are typically intended to service high call volumes, reduce cost and improve the customer experience. Examples of typical IVR applications are telephone banking, televoting, and credit card services. ...
Voice-Activated Dialing
... (VAD) IVR systems are used to automate routine enquiries to switchboard or PABX (Private Automatic Branch eXchange) operators, and are used in many hospitals and large businesses to reduce the caller waiting time. ...
Entertainment and information.
Some of the largest installed IVR platforms are used for televoting on television game shows, ... which can generate enormous call spikes. Often, the network provider will have to deploy call gapping in the PSTN to prevent network overload. ...
Anonymous access.
IVR systems allow callers to obtain data relatively anonymously. Hospitals and clinics have used IVR systems to allow callers to receive anonymous access to test results. ...
Clinical trials.
IVR systems are used by pharmaceutical companies and contract research organizations to conduct clinical trials and manage the large volumes of data generated. ... Applications include patient randomization and drug supply management. ...
Outbound calling.
IVR systems can be used for outbound calls, as IVR systems are more intelligent than many predictive dialer systems, and can use Call Progress Detection to recognize different line conditions...
Other common IVR services include:
Mobile - Pay-As-You-Go account funding; registration; mobile purchases, such as ring tones and logos;
Banking - balance, payments, transfers, transaction history;
Retail & Entertainment - orders, bookings, credit & debit card payments;
Utilities - meter readings; account look-up, history and balance, payment, consumption history;
Travel — ticket booking, flight information, check-in;
Weather forecasts, water, road and ice conditions" [Interactive voice response. Wikipedia]

"Call centers use IVR systems to identify and segment callers. The ability to identify customers allows services to be tailored according to the customer profile. The caller can be given the option to wait in the queue, choose an automated service, or request a callback. The system may obtain caller line identification (CLI) data from the network to help identify or authenticate the caller. Additional caller authentication data could include account number, personal information, password and biometrics (such as voice print).
When an IVR system answers multiple phone numbers the use of DNIS ensures that the correct application and language is executed. A single large IVR system can handle calls for thousands of applications, each with its own phone numbers and script.
IVR also enables customer prioritization. In a system wherein individual customers may have a different status the service will automatically prioritize the individual's call and move customers to the front of a specific queue. Prioritization could also be based on the DNIS and call reason." [Interactive voice response. Wikipedia]
