we don't do the RTP activity detection yet (although it's on our todo<br>
list). To detect when one of the parties is down on the SIP level make<br>
sure to enable SST (config.yml should have session_timer.enable: yes).<br>
<br>
To find when the parties stop sending the RTP traffic just use tcpdump<br>
or wireshark. Tshark can write to capture "ring buffer" of multiple<br>
files that are automatically rotated if you have much traffic, e.g.:<br>
tshark -b filesize:10000 -b files:50 -w spce_tshark.pcap port not 22<br>
