Asterisk adjust gain

How to tune the volume in asterisk system



configure zapata.conf



rxgain represents the receive volume

txgain represents the transmit volume


Default value is 0.0


PS:Most reading suggests going no lower than -11.0 and no higher than 11.0, though it will take values from -100 to 100.Make sure that rxgain=/txgain= lines are placed prior to channel= line in your zapata.conf otherwise the gain settings will not have any effect.
