The 4-line Dialogic D/41D™ boards are ideal for applications that need high-performance voice processing but don't require the large-scale system sophistication of SCbus™ or CT Bus™ based products. The Dialogic D/41D boards use the Dialogic application programming interface (API) to take advantage of the power and features of these Dialogic boards.
Telephone signals traveling over telephone lines can be recorded and played back with great clarity. The Dialogic D/41D boards use the digital signal processor (DSP) voice processing technology, making them ideal for small- and medium-sized, server-based computer telephony (CT) systems — particularly under the Windows® operating systems. Windows support includes TAPI and WAVE APIs, which facilitate call control, recording, and playback of voice messages under the Microsoft Windows Open Services Architecture (WOSA). The D/41D voice processing Dialogic boards give Windows 95 and Windows NT® application developers a powerful platform for creating sophisticated interactive voice response (IVR) applications.
