<div name="messageBodySection" style="font-size: 14px; font-family: -apple-system, BlinkMacSystemFont, sans-serif;">Hi!
<div><br /></div>
<div>Is there any way to make silence detection on start of the call?</div>
<div>Like answer a call, playback a ringtone back to legA, and meanwhile try to understand, if legB is totally silent. If it is silent for, let’s say 5 sec - hangup the call.</div>
<div><br /></div>
<div>One of ways to fight spam machine calls (yes, sometimes it looks like DoS attack)</div>
<div><br /></div>
<div>Right now only thing I can imagine - record legA to file and than analyze recording for silence.</div>
</div>
