IVR systems interactive voice response

IVR Interactive Voice Response

This section of our technical library presents information and documentation relating to IVR and interactive voice response software as well as automatic call answering solutions. Business phone systems and toll free answering systems (generally 800 numbers and their equivalent) are very popular for service and sales organizations, allowing customers and prospects to call your organization anywhere in the country. Our PACER and Wizard IVR systems add another dimension to our call center phone system solutions. An Interactive Voice Response (IVR) processes inbound phone calls, plays recorded messages including information extracted from databases and the internet, and potentially routes calls to either in-house service agents or transfers the caller to an outside extension.

Using IVR Report Server Client API

Structures and Constants


From “IrsApiErrors.h”:


#define IRSAPI_SUCCESS                 0

#define IRSAPI_ERROR                  -1




#define IRSAPI_ERR_NOTFOUND           -5


These are the only “errors” one should expect to receive (excepting IRSAPI_RT_INVALID, explained below).


IRSAPI_SUCCESS – Not an error.

IRSAPI_ERROR – Generally should only be returned if there is a version mismatch between the client using the IrsClApi32 and DscIRS.

IRSAPI_ERR_COMMUNICATION – This will be returned if there was some systemic error in establishing communication with dscnmq (usually the service is not running).

IRSAPI_ERR_MISSINGHOSTNAME / IRSAPI_ERR_MISSINGSERVERNAME – Usually results from a failure to initialize the DLL with a call to IRSSetServer().

IRSAPI_ERR_NOTFOUND – Sometimes not really an error, this results from a data request in which no records were found.

DSC provides IVR software including our IVR wizard development tool for creating interactive voice response applications. Our IVR software lets you increase IVR development productivity by providing a visual development environment. IVR applications can be defined in minutes using this sophisticated, yet easy to use development tool. DSC also has available a comprehensive IVR software library known as our IVR Wizard Software Development Kit. This optional package is available for programmers and systems adminstrators who wish to manage IVR programs fromLinux IVR, Unix, or Windows IVR operating environments.

Data collected by your phone ACD (Automatic Call Distribution) or IVR (Interactive Voice Response) systems can be passed to your existing PC, Unix or Web applications through our phone software. The PACER predictive dialer can automatically call your customers and pass only connected calls to your agents. With our computer telephony software, your telephone and computer work together to provide cost-saving benefits.
