I don&#39;t believe you can reliable put these tones in synch. I&#39;ve never heard of any telephony system that does so, although I admit my experience is limited to legacy PBXes and FreeSWITCH.<div><br></div><div>-MC<br>

Hi,<br>
<br>
&gt; I&#39;m not sure that I understand what the issue is here. What two &quot;tones&quot;<br>
&gt; are<br>
&gt; not in sync? You said &quot;dial tone&quot; but I&#39;m pretty sure that&#39;s not what you<br>
&gt; mean. Are you talking about the ringback tone that the caller hears?<br>
<br>
Exactly Michael, I was talking about the ringback tone.<br>
I didn&#39;t know the correct expression and used a translation engine...<br>
