Hello, I sent a wav-audio to Asterisk though SIP and ISDN channels and recorded it in wav-audio at the Asterisk server. I found the loudness level of the recorded audio was too high comparing with the orginal audio. How can I ajust it, so that there will be no amplifier used for recording. Thanks a lot. best regards Felix two options are: 1. reduce RXgain - assuming your are using Record() command 2. use sox to reduce the volume; something like sox -v .8 file1.wav file2.wav
