Calloriented

Calloriented is an informal term used in information technology and communications to describe approaches, architectures, or design philosophies that are organized around calls—either function calls in software or telephone calls in telecommunication. The term is not widely standardized and may appear in technical discussions as a descriptive label rather than a formal classification.

In software engineering, call-oriented design refers to programming styles or API designs in which the primary units of computation are individual calls to procedures or functions, with control flowing through a sequence of invocations. This can contrast with data-oriented or event-driven paradigms where processing is driven by data state changes or external events. Call-oriented interfaces often emphasize clear call graphs, modularity, and explicit control transfer, sometimes at the expense of implicit data-driven optimization or reactive behavior.

In telecommunications and contact centers, a call-oriented approach focuses on the lifecycle of a telephone call: routing, queuing, interactive voice response, holds, transfers, and associated metrics such as call duration and first-call resolution. Systems described as call-oriented typically feature integrated telephony capabilities, routing policies, and stateful management of active calls.

Origins and usage of the term vary, and it is not a formal designation in standard reference works. It is best understood as a descriptive label indicating a design or operational emphasis on calls in a given domain.
