"A SIM box (also called a SIM bank) is device used as part of a VoIP gateway installation. It contains a number of SIM cards, which are linked to the gateway but housed and stored separately from it. A SIM box can have SIM cards of different mobile operators installed, permitting it to operate with several GSM gateways located in different places." [SIM box. Wikipedia]
The IVR diagram example "VoIP call with SIM box and gateway" was designed using ConceptDraw PRO diagramming and vector drawing software extended with the Interactive Voice Response Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

"DTMF decoding and speech recognition are used to interpret the caller's response to voice prompts. DTMF tones are entered via the telephone keypad. ...
Other technologies include using text-to-speech (TTS) to speak complex and dynamic information, such as e-mails, news reports or weather information. TTS is computer generated synthesized speech that is no longer the robotic voice traditionally associated with computers. Real voices create the speech in fragments that are spliced together (concatenated) and smoothed before being played to the caller.
An IVR can be deployed in several ways:
1. Equipment installed on the customer premises.
2. Equipment installed in the PSTN (public switched telephone network).
3. Application service provider (ASP) / hosted IVR.
IVR can be used to provide a more sophisticated voice mail experience to the caller. ...
An automatic call distributor (ACD) is often the first point of contact when calling many larger businesses. ...
IVR call flows are created in a variety of ways. A traditional IVR depended upon proprietary programming or scripting languages, whereas modern IVR applications are generated in a similar way to Web pages, using standards such as VoiceXML, CCXML, SRGS and SSML. ...
In telecommunications, an audio response unit (ARU) is a device that provides synthesized voice responses to DTMF keypresses by processing calls based on (a) the call-originator input, (b) information received from a database, and (c) information in the incoming call, such as the time of day.
ARUs increase the number of information calls handled and provide consistent quality in information retrieval." [Interactive voice response. Wikipedia]

This business process flowchart example was redesigned from the Wikimedia Commons file: Proposed Patient Appointment Procedure.png.

"The example is Proposed Patient Appointment Procedure. It starts with "preparation of appointment book" followed by a decision whether the appointment is shore or fleet. If the appointment is fleet, inform patient they can call 1500 to make own appointments for next few days, if the appointment is shore, confirm 24 hours prior to appointment. Next confirm that the patient confirmed. If a patient did not call, the appointment is canceled, otherwise the patient is given a confirmation number. Finally confirm that the patient showed for the appointment. If not, a standby patient is placed in the appointment slot, the appointment book is marked “Failure” and a failure report is submitted from front desk to fleet liaison. If a patient showed for appointment, put “Patient showed” in appointment book." [Business process mapping. Wikipedia]

"The builder pattern is an object creation software design pattern. Unlike the abstract factory pattern and the factory method pattern whose intention is to enable polymorphism, the intention of the builder pattern is to find a solution to the telescoping constructor anti-pattern. ... The intent of the Builder design pattern is to separate the construction of a complex object from its representation. By doing so the same construction process can create different representations."

"A call centre or call center is a centralised office used for the purpose of receiving or transmitting a large volume of requests by telephone. An inbound call centre is operated by a company to administer incoming product support or information inquiries from consumers. Outbound call centers are operated for telemarketing, solicitation of charitable or political donations, debt collection and market research. In addition to a call centre, collective handling of letter, fax, live support software,social media and e-mail at one location is known as a contact centre.
A call centre is operated through an extensive open workspace for call centre agents, with work stations that include a computer for each agent, a telephone set or headset connected to a telecom switch, and one or more supervisor stations. It can be independently operated or networked with additional centres, often linked to a corporate computer network, including mainframes, microcomputers and LANs. Increasingly, the voice and data pathways into the centre are linked through a set of new technologies called computer telephony integration (CTI)." [Call centre. Wikipedia]

"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.
