Modify your dial-plan to route conference-bridge calls, to go to the PBXMate. So the flow will be:</span></div>Phone->PBXMate (Sip Trunk) -> Conference Bridge.<span><br><br>Now, for each call, the PBXMate will show you the noise level on both sides, i.e. the noise level going upstream to the conference bridge and the noise level going down-stream to the phone. This should give you an insight to analyze the problem. <br><br>As a bonus, the PBXMate will also clean the noise. </span><div><br></div><div><br></div><div><br></div> <div style="font-family: times new roman,

<div><font face="Arial" size="2">I am trying to track down a white noise problem we
are having in our conference rooms. If there are 3 or 4 users in the conference
the quality is good. After we get more users in the conference we develop a
white noise that gets louder as more users come online. I have tried both meetme
and confbridge. I am running 1.8.16.0 compiled from source.</font></div>

<div><font face="Arial" size="2">Can anyone provide some insight on where to look or
anything to tweak to resolve this?</font></div></div>
