I have an asterisk box using a SIP provider and IAX2 softphones clients.

Audio is low and I need to apply some gain on it. How can I configure such
gains – in/out on sip and iax2 channels?

Thanks,

Valter

  • You can’t do this on the channels themselves; VoIP channel drivers don’t
    manipulate the audio content of the channels, they pass it through.
