IVR Library Functions and Features

ivr manual Database Systems Corp. (DSC) provides an API library of IVR (Interactive Voice Response) routines.

An IVR application functions in a client/server environment. The IVR program can run on the IVR phone system or on a different server that is processing your application programs.

The IVR program now has complete access to all of the same information as your application programs. It can actually perform call center functions such as dealer lookup, account information access and update, etc. and simply transfer the result information to the our phone system to be relayed to the caller.

Some of the basic features of the our IVR programming system are:

    ivr manual phone
  • Client/server architecture
  • Visual Basic, C, C++, Active-X, and .NET support
  • VoiceXML data access
  • DNIS controlled
  • Inbound and outbound call processing
  • Record messages
  • Play music on hold
  • Multiple IVR scripts
  • Play message and prompt
  • Play mixture of recorded message and text
  • Phone key input
  • User navigation and selection
  • Voice mail
  • Database access and update
  • Text to speech (TTS)
  • Perform application functions
  • IVR response logging and reports

IVR Programming Environment

The DSC IVR comes with several libraries that are compatible with multiple programming languages. The following are the languages currently supported:

  • C and C++ programming languages
  • Visual basic (Microsoft)
  • Active-X
  • .NET
Contact DSC for the latest user guide's associated with these and other programming languages.

How Our IVR Works

Upon receiving a call, the DSC phone system uses the DNIS to check for an IVR script. The IVR Client process invokes a server process on the application server and starts a two-way communication with the IVR Server.

An IVR program controls the flow of the IVR script by prompting the caller and requesting key input or directing the caller to another DNIS, extension, or Voice Mail. In the process, this IVR program can perform any application function including report generation, customer information lookup, etc.

Our IVR can also initiate outbound calls and prompt the called individual with the same messages (and text) and accept phone key input from this individual as well. The caller and called individual can likewise be “connected”.

IVR Administration

The DSC phone system includes a setup window for IVR scripts. Upon definition of a DNIS entry, the administrator can designate that callers on this DNIS will be automatically routed to an IVR script.
