I read the recent issue regarding detecting speaker events in a conference to determine silence, so I suppose I instead of bridging I could put the two legs into conference and look for the lack of a ‘start talking’ event within some number of seconds. But I would prefer to sick with bridging the legs if possible. I am unclear about how the recording is going to look in the case where there is no RTP coming in, and whether I could really inspect the recording to know for sure whether or not I am receiving packets….<div class=""><br class=""></div><div class="">Dave<br class=""><div class=""><br class=""></div><div class=""><br class=""><div><div class="">On Jan 17, 2016, at 5:29 PM, Stanislav Sinyagin <<a href="mailto:ssinyagin@gmail.com" class="">ssinyagin@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><div class="">you can, for example, start a recording within a running session, run it for 10 seconds, and then build a histogram using SOX.

The need stems from a desire to detect a one-way audio situation in rare nat’ed scenarios where signaling gets established but one party may have restrictive firewall rules preventing his/her RTP stream from reaching the FS endpoint.
