Hello.
We are running a bigbluebutton browser-based webinar server and having some issues with Freeswitch audio quality.

We often get some strange audio "noises".Here is a very short sample  (it starts at ~ 30+ seconds) https://drive.google.com/file/d/1XOIsofU2nD5vfZC8F7khGeIXV4KVIDBI/view
It's a bare metal server,(ubuntu 16.04, l4.15.0-65-lowlatency kernel, 4 cores, 16GB ram, 1 GBit uplink.)

What changes in switch.conf.xml(conference.conf.xml, sofia.conf.xml other config files) could be made to fix this issue?
Thank you!
