You cannot detect silence on an encoded format because you would have to decode it to be able to detect the silence.<br>If you want to detect silence use a standard wav/pcm format.<br><br><br><div class="gmail_quote">On Fri, Sep 4, 2009 at 3:52 PM, Peter Volchek <span dir="ltr"><<a href="mailto:pvolchek@voicemobility.com">pvolchek@voicemobility.com</a>></span> wrote:<br>

I am getting the warnings in the <a href="http://freeswitch.org" target="_blank">freeswitch.org</a> , saying...<br>
<br>
[WARNING] switch_ivr_play_say.c:567 Can't detect silence on a native<br>
recording.<br>
<br>
This is thrown each time I am calling session:recordFile in my lua<br>
scripts. I am not specifying any extensions, thus relaying on the<br>
encoding type chosen by freeswitch. So the files are given extensions .PCMU.<br>
I've been told that this is a harmful warning.<br>
However, we need an ability to detect the silence in the following scenario.<br>
In a voicemail, while the caller is leaving a message, he can mute his<br>
phone. The application may kick up the event, saying that silence is<br>
detected, so we would pause the recording and play the prompt "Are you<br>
still there?" to the caller.<br>
<br>
Thanks.<br>
