Interactive Voice Response Diagrams

"A business process or business method is a collection of related, structured activities or tasks that produce a specific service or product (serve a particular goal) for a particular customer or customers. It often can be visualized with a flowchart as a sequence of activities with interleaving decision points or with a Process Matrix as a sequence of activities with relevance rules based on data in the process. ...
There are three types of business processes:
(1) Management processes, the processes that govern the operation of a system. Typical management processes include "corporate governance" and "strategic management".
(2) Operational processes, processes that constitute the core business and create the primary value stream. Typical operational processes are purchasing, manufacturing, advertising and marketing, and sales.
(3) Supporting processes, which support the core processes. Examples include accounting, recruitment, call center, technical support. ...
The ... improvement areas are equally applicable to policies, processes and detailed procedures (sub-processes/ tasks). There is a cascading effect of improvements made at a higher level on those made at a lower level.
For instance, if a recommendation to replace a given policy with a better one is made with proper justification and accepted in principle by business process owners, then corresponding changes in the consequent processes and procedures will follow naturally in order to enable implementation of the policies" [Business process.

The BPMN 1.2 (Business Process Model and Notation) diagram example "Taxi service order procedure" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Business Process Diagram solution from the Business Processes area of ConceptDraw Solution Park.

This interactive voice response (IVR) diagram sample illustrates how ENUM call forwarding can be achieved. It was designed on the base of the Wikimedia Commons file: Call Forwarding with ENUM.jpg. [commons.wikimedia.org/ wiki/ File:Call_ Forwarding_ with_ ENUM.jpg]
"Telephone number mapping is a system of unifying the international telephone number system of the public switched telephone network with the Internet addressing and identification name spaces. Internationally, telephone numbers are systematically organized by the E.164 standard, while the Internet uses the Domain Name System (DNS) for linking domain names to IP addresses and other resource information. Telephone number mapping systems provide facilities to determine applicable Internet communications servers responsible for servicing a given telephone number using DNS queries.
The most prominent facility for telephone number mapping is the E.164 Number Mapping (ENUM) standard. It uses special DNS record types to translate a telephone number into a Uniform Resource Identifier (URI) or IP address that can be used in Internet communications." [Telephone number mapping.
