As a slight aside on the subject of gain.... It seems that most people asking about RX/TX gain want to increase their volume. I have the opposite problem: I have a Digium TDM10B FXS card that generates sound far too loud (in the earpiece) with the RX gain set at 0.0, or commented out. That is, routing an analog line => X101P => Asterisk => TDM10B => analog phone is MUCH louder than if I just plug the same phone into the same analog line directly. Some people have suggested that using a negative gain will make it quieter, but I haven't had any luck with this. I *can* make it even louder by increasing the gain -- if I use "rxgain = 10" on the TDM10B, for example, it's so loud it sounds like the phone is going to explode -- but using things like "rxgain = -3.0" or "rxgain = -10.0" doesn't make it any quieter. I can't get it below the "rxgain = 0" value. I've been meaning to dig around the source and see what's up, but since it's being discussed... anyone know how to use rxgain to lower the earpiece volume? -- Robert L Mathews, Tiger Technologies http://www.tigertech.net/ _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
