Asterisk Voice changer


Please any one can guide me how I can do asterisk voice changing on asterisk 13.11

What do you mean by Voice changing?
Do you want to increase/decrease the tx/rx gain of any channel?
If yes then have a look at

If is change the voice instead of increase the volume use the function PITCH_SHIFT()

exten=>100,1,Set(PITCH_SHIFT(both)=1.5) ;
