Hi, thanks <span></span>Kristian for your answer, it make sense<br>
<br><div class="gmail_quote">2009/11/12 Kristian Kielhofner <span dir="ltr"><<a href="mailto:kristian.kielhofner@gmail.com" target="_blank">kristian.kielhofner@gmail.com</a>></span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
The simplest way I know of is to bring up another call from a local<br>
phone and listen to the audio. At the same time run tcpdump/etc with<br>
a strict filter to capture the rtp to/from that phone. You can then<br>
run RTP stream analysis and the like in Wireshark to identify any lost<br>
packets. While this obviously won't identify any/all potential lost<br>
packets it will be a lot more practical than any of the alternatives:<br>
<br>
- Capturing all media streams for RTP analysis<br>
- Implementing RTCP to identify lost packets<br>
- Commercial hardware/software<br>
<br>
If FreeSWITCH, your machine, or your network are pushed to the max and<br>
falling apart you're most likely going to see audio problems on your<br>
single (captured) call.<br>
