Hi,<div>CRBT is caller ring back tone. What you are primarily looking at is <span></span>sending the INVITE to some b2bua like FreeSWITCH or Asterisk where you control both legs of the call. So when you get a ringing signal from the B-leg, you play some media file on the A-leg. </div>

    <div><tt>Hello,<br>
        <br>
        No sure what CRBT stands for, but it looks to me that you need
        to use B2B module - what you are trying to do is something more
        than simply proxying a call.<br>
