FreePBX call recording - increase volume on one stream

I have a FreePBX installation and have set the Call Recording options on both the Inbound and Outbound Routes to Yes.

Call recording is happening for both inbound and outbound calls but the inbound stream is so quiet that it's inaudible.

Is there a way to increase the volume of just a single stream.

I am aware of the tx and rx gain commands but those change the volume for everything and we have no problem hearing callers during any calls.

Solution

  • After recording process done, you can execute script(see general settings in freepbx).

    In that script you can use sox or any other convertor and increase gain on one channel. Asterisk save caller+called as left/right channel in mixed call.
