In sip.conf, add rxgain=-4.0 to the peer. This (feel free to correct) should reduce the incoming volume by 4 decibels. You'll have to do a "sip reload" for this to take effect.

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 -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
