Hi Marty, thank you for your suggestion, but... just done and nothing happens. The perfect RX gain for me is 6.0; if I change the TX nothing really happens, but if I move it to a value less than 0.0, less than that I cannot ear anything... strange but true. As I said, on internal calls everything works fine, without any echo. When I make external calls (pstn with digium TDM400P) I ear an echo just at the begin and at the end of any speech. If I say short words (sounds) then I hear a lot of echos. Isn't it a sidetone effect? Any other ideas? Thanks again, Marco
