<div><div style="color:#000;background-color:#fff;font-family:times new roman,new york,times,serif;font-size:12pt">is there a method using xml that i can prevent callers three waying themselves. I find some idiots will do this so they can &quot;produce&quot; feedback into a conference room. I would like the system to automatically determine that they are already on the ivr and send them to a recorded message and hangup. or maybe auto hanging up the first call in case of &quot;accidentals&quot; from voips not hanging up  and continuing the first call.<br>
