1.23 Voice Function Support by Platform
Table 1 provides an alphabetical listing of voice API functions. The table indicates which platforms
(DM3 or Springware) are supported for each of the functions.
DM3 boards refers to products based on the Intel® DM3 mediastream architecture. Typically DM3
board names have the prefix “DM,” such as Intel® NetStructure™ DM/V2400A-PCI. Springware
boards refer to boards based on earlier-generation architecture. Typically Springware board names
have the prefix “D,” such as Intel® Dialogic® D/240JCT-T1.
Although a function may be supported on both DM3 and Springware boards, there may be some
restrictions on its use. For example, some parameters or parameter values may not be supported.
For details, see the function reference descriptions in Chapter 2, “Function Information”.
