[Freeswitch-users] How to control call volume?

[Anthony Minessale]

The volume should really be set on the devices who are originally encoding
the audio (the phone or analog card)
Digital audio never changes so the server is not the right place to mess
with the volume because you will have to actually manipulate the digital
signal to do it.  We have a way but I recommend you find the real source of
your problem.

<action application="set_audio_level" data="read 1"/>

change read to write if you want to do it going the other way
