Hi,<br><div><br></div><div>I just found that tone_detect worked sometimes and sometimes it didn&#39;t work. For a short length of tone like 100ms, it worked well. But for a much longer one (700ms or 1sec without pause), it didn&#39;t work. This one has not been detected but in the recording file, it was obvious. </div>

<div><br></div><div>by this wiki <a href="http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_tone_detect">http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_tone_detect</a><br></div><div>I don&#39;t know how exactly the <b><i>hits</i></b> works. </div>

<div><br></div><div>And later I found these 2 variables called <b><i>tone_detect_sleep</i></b> and <i style="font-weight:bold">tone_detect_expires. </i>But I didn&#39;t find any explanations about them.</div><div>Can anybody bring more details?</div>
