The unique DSP processing structure, can real-time, highly efficient digital recording every line of independence and playback.
The unique DSP processing structure, each line of the digital recording and playback can simultaneously and independent.
Can dynamically select a different voice encoding speed, and real-time speech compression and decompression, such as the 32kbps ADPCM, 64kbps PCM.
Provided the reliable buttons (DTMF) detection, the recording and playback, immediate response DTMF buttons.
The unique signal Generation) and (Detection algorithm identification (can accurately identify the audio signal frequency of arbitrary or any of the audio signal frequency.
Reliable two lines of modem testing simulated relay.
With polarity reversal and speech recognition, can accurately identify each other pick.
With a caller ID (Calling) Identity Delivery.
With ST - BUS and MVIP - BUS BUS, can achieve inside the arbitrary card carried between any two channels between the exchange.
Card with a processor and large capacity, no additional CunZhuQi occupy host resources.
The card can identify pew pick, hang up and shoot inserts such action.
The driver using event-driven structure, convenient multi-channel programming.
Don't need additional hardware, can achieve tripartite conference calls and function
Bring your Text with TTS function.
