Voice Logging Board

In order to satisfy the high-performance requirement in monitoring of voice logging field, Donjin has launched high-performance voice logging board and corresponding voice logging solution. The voice logging products include high-impedance analog voice logging board, high-impedance USB voice logging board, and high-impedance digital trunk voice logging board.

High Density Digital Trunk Voice Board

It can satisfy customer requirements for high-performance and high-density service solutions, such as telecom-grade voice chat or telephone conference, voice advertisement (OBD), and outsource call center. Provide these services with high-capacity and stable voice, conference, signaling and FSK/DTMF functions. This board can help telecom device manufacturers to explore device-grade market combined with new computer platform and application. The boards adopt NADK SDK, provide Dialogic SR5.11 compatible API programming interface.

Analog Trunk Voice Processing Board

It adopts DSP technology to apply multiple voice processing functions. The hardware is composed of motherboard and module and provides 8 channels and 16 channels motherboard, trunk, 2-channel voice, and 4-channel voice modules. It can apply different scale and function by different motherboards and modules. Single chassis can support several Donjin voice boards collectively to apply trunk, play, record, FSK, and speech synthesis functions.
