the buzzing is probably a 60hz ground loop from the device that is calling in.<br>Try using a different outlet, a different device, or if it&#39;s a cordless device like a laptop, try it with the power cable<br>unplugged and only use battery to test it.  Typically there is nothing we can do being on the receiving end of such noise.<br>

Hi,<br><br>I&#39;ve been asked to do some testing on Freeswitch by work, we currently use Asterisk.  I&#39;m quite new to telephony so please go easy.<br><br>I have FS setup on a windows box and at the moment I&#39;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.  <br>
<br>Hopefully this is enough info cheers for any help.<br><div class="hm"><br><hr>&quot;
