Hi,

I've been asked to do some testing on Freeswitch by work, we currently use Asterisk.  I'm quite new to telephony so please go easy.

I have FS setup on a windows box and at the moment I'm testing internal calls only, when I transfer calls or call extensions everything sounds great.  The problem occurrs when I setup conferencing, people can log in ok and we can talk, the trouble is as people start to talk a buzzing sound is heard in the background, once the talking stops the buzzing stops.  If the person goes on mute there is no buzzing.
