Subject: [Freeswitch-dev] VAD, TALK and NOTALK events<br>
<br>
Hi,<br>
<br>
>From looking at the code of switch_rtp.c I can see that VAD is done
if<br>
enabled in the sip profile in order to not send packets when there is no<br>
noise. There are also two events {TALK, NOTALK} which can be fired when VAD<br>
kicks in, nevertheless these two events are enabled nowhere (or at least I<br>
didn't find a place in the code where they were enabled), so no matter if<br>
you ask for them you don't receive them. My questions are the following:<br>
<br>
Is there some particular reason for not enabling these two events? <br>
Is the event queue easily overflowed if these two events are enabled?<br>
<br>
Thanks.<br>
<br>
Cesar Cepeda.<br>
<br>
