Components of an IVR System

An IVR system contains telephony equipment, multiple software applications, a referential database, and any supporting infrastructure.

Telephony Equipment

Telephony is a phone technology that can electronically transmit voice and other information between two parties in distant locations using a telephone/mobile device that carries a speaker/transmitter and a receiver.

Referential Database

Referential databases are databases that follow a relational concept that says each table in the database must have relationships that are always consistent. Overall, this means that foreign key fields must agree with the primary keys referenced by the initial foreign key.

Supporting Infrastructure

Regarding IVR systems, supporting infrastructure is a collection of hardware, networks, data centers, software, and facilities used to develop, test, and monitor the IVR system technology.
