Hello! Me and my team ready to do it. We use Altuim designer for PCB. .Net for desktop application. We have experience with telephone's adapters and USB devices. We suggest to use PCM2903C USB audio codec fromTI - PC will see this chip as audio card. Simple cortex-M3 MCU (like STM32F030) will be used for control function (hangup, caller ID, ring, DTMF and so on) as HID device. So, your device will use standard drivers for windows Best regards, Marsel

Hi. I have experience of developing GSM-PSTN gateway. My bid includes 2 prototypes soldering and fast shipping to you. First prototype for you second for me. You will test hardware and I will fix your requirements. Be honest I have not experience with HT82A834R and it's not available in my local shops. My prefferred MCU is STM. I'm thinking about using MCU as audio device STM has examples for that.
