[asterisk-users] Asterisk Voice sound level

[Alex Robar]

Hi Erik,

Asterisk by itself does not have the ability to alter the media stream with
regards to volume. Your zap config will allow you to set rxgain and txgain
for the Austrian ISDN, but that might not suit your purposes for all other
calls that use this trunk.

I believe it was mentioned here before that this might be an interesting
application for Justin Tunney's VoiceChanger application (
http://www.lobstertech.com/code/voicechanger/ ). It's a replacement for the
dial command that alters the pitch of the media stream in real time. I
imagine that with some work, a VolumeChanger application could be written
based off of VoiceChanger.

Cheers,
Alex
