Example applications:

• Unified messaging (UM) server (Fax, email, voicemail, SMS, VoIP).
• Fax server applications, sending and receiving faxes.
• Voice applications, making and receiving voice calls over analog, ISDN, E1/T1, SS7 or VoIP connections.
• Computer telephony integration (CTI) server; for example: DTMF detection, recording and playback of .WAV files.
• Telephony supplementary services (including line interconnect, conferencing, hold/retrieve, transfer).

The Diva Component API supports both very simple and more complex applications

• Simple single-call programs can use 'blocking' (also known as 'synchronous') operation
• More complex multi-call applications can use 'non-blocking' (asynchronous) operation and can use 'events'
• Fully-scalable applications can be built by defining a 'call-handler' class to handle 120 or more calls

The Diva Component API is a simple, high level API that allows most of the call control offered by low-level APIs, but with much greater ease-of-use:

• The programmer does not need detailed knowledge of underlying technology and protocols.
• Unnecessary communications complexity is hidden from the programmer, allowing the programmer to concentrate on adding value and speeding development.
• Default values for method parameters (not available in C#) make simple applications quick and simple to create and errors are reduced.
• At the same time, for more advanced applications where more precise control over calls is required, GetCallProperty and SetCallProperty (new in SDK 4.0) provide access to the same low-level call properties available in the Diva API for C++
