I just bought a GW1200. I have successfully connected it to my sip phones either directly or via a freeswitch. The problem I have is that a noise reduction circuit seems to be active in the call. This makes it hard for an IVR system with speech recognition to work properly. Is there a way to disable the noise reduction. I'm using G711 from the GW1200 towards my freeswitch and IVR. I have tried to change the RX/TX gains to 0 but with not much luck.
