Intel DIALogic D/41EPCI 4-Port PCI Voice Interface Card

The D/41EPCI is a four-port analog voice processing board ideal for developers building enterprise voice messaging and IVR applications for the global market. The D/41EPCI provides four telephone line interface circuits for direct connection to analog loop start lines. A dual-processor architecture, comprising a DSP (digital signal processor) and a general-purpose microprocessor, handles all telephony signaling and performs DTMF (touch tone) and audio/voice signal processing tasks. The open architecture enables developers to build CT solutions using products from multiple vendors. And since you can install multiple D/41EPCI boards in a single PC chassis, you can build systems scaling up to 64 ports.
