Hi this is odd, almost more than 7 years for this problem and no answer from community, I tries a us robotic, an smartlink and 2 zoltrix modems with 3 PCs and had the same problem with droping incoming calls and not making outgoing calls which I believe the application cant afford outgoing calls with voice modems. so let me focus on incoming calls which suppose to be working but it drops the call after almost 2 rings and if you answer it will drop immediately. any solution to this ?
