I recently picked up an OBi200. Works well for the most part but the person on the other end says that my voice is really quiet. I want to change the TX gain. When I go into the web interface, "default" is unchecked for TX and RX gain and TX gain is set to -5 while RX gain is sent to -4. If I either try to change them, or check default, and save and restart, it goes right back to how it is - gains of -5 and -4.
What do I need to do to change these parameters? Is something wrong with my unit?
