2. The Dialogic R4 API for DM3

2.1. Introduction to R4 for DM3

The term "Dialogic R4 API" ("Dialogic System Software Release 4 Application Programming Interface") is used to identify the Dialogic well-established and time-proven direct interface used for creating computer telephony application programs. The R4 API is actually a rich set of proprietary APIs for building computer-telephony applications tailored to Dialogic hardware products. These APIs encompass technologies that include voice, network interface, fax, and speech.

The R4 API now supports a new generation of Dialogic hardware products, which are based on the Dialogic DM3 mediastream product architecture.

When this documentation uses the name "R4 for DM3" and "R4 on DM3," it refers to specific aspects of the R4 interface that relate to support for DM3 products.

NOTE:

The terms SpringWare boards (or SpringWare devices) and earlier-generation boards (or earlier-generation devices) are used interchangeably in this document. These are boards whose device family is not DM3, such as the Dialog/HD series of boards.
