PURPOSE: A UnPBX system for processing multi-channel voice data in real time and a method therefor are provided to process multi-channel voice data in real time by embodying memory buffers that store necessary data to record or regenerate voice data for VMS(Voice Mailing System) service or IVR(Interactive Voice Response) service by channels. CONSTITUTION: A voice signal processing board transfers many subscribers' voice data to a server through multiple channels in real time and delivers voice data regenerated from the server to the multi-channel subscribers in real time. The voice signal processing board consists of a common memory(210), a plurality of memory buffers(220), a plurality of voice signal processing parts(230), and a control part. The common memory(210) transmits and receives data with a main memory by an ISA(Industry Standard Architecture) interface. The memory buffers(220) store necessary data to record or regenerate voice data by channels. The voice signal processing parts(230) process the recording or regeneration data stored in the common memory(210). The control part controls the operations of the common memory(210), the memory buffers(220) and the voice signal processing parts(230).
