What is a dialogue card?

The

dialogue card acts as an interface between analog phone signals and a peripheral component or a PCI bus, found on computers. Buses on the computer act as channels connecting different components. The dialogue card processes information from analog phone lines and is used in applications such as voice messages, notification systems, automatic dialers and voice mail. They are also used for interactive voice response, automatic call distribution and voice or sound response systems. Dialogical cards are used in many product recordings that are produced in digital and analog configurations depending on the way they are used.

allowing high density applications, dialogues are usually used in automatic telephone systems with services such as predictive dialing and conferences. There are cards that can handle a number of phone calls at the same time. The dialogue card can even bringto keep every call to the correct representative. The basic function of the dialogical card is intended to integrate computers with phones and allows a wide range of features. Internal distributed bus switching allows you to redirect incoming and outgoing calls.

Voice decoding and coding, obtaining calling number calling and call IDs, and answering calls are possible through a dialogue card. It can detect touch tones dialed, record sounds from the telephone line and identify when the connection was interrupted. Most cards can handle many analog lines and have protective circuits on board that make them very reliable. Some signaling functions, such as the latest detection, can not only monitor, but also control the computer using a dialogue card. It is also possible to configure multiple boards within one chassis and easily expand the number of analog ports if necessary.

earlier applications for dIog cards were written by telephone programming interface or API, such as dialogical R4, GlobalCall and ECTF S.100. ActiveX controls, such as API based on visual voice and Java API, including API and JTAPI, were also used to create telephone applications. But everyone had numerous problems. Java -based APIs are no longer used and ECTF S.100 is used very rarely. Over time, other proprietary scripting languages ​​were also abandoned.

All this API was limited to very specific operating systems and were not widely admitted as standards. Everyone fell into abuse, as more modern, web standards. The two widely used telephone standards that have become popular over time were Voicexml and CCXML. They have another advantage that they are based on the ubiquitous XML and HTTP, which makes it easier to use web technologies.
