on the Kurento server, as root run `tcpdump -i any -s 0 -w capture1.pcap` then run the scenario, then Ctrl-C the command after the call is complete and gather the...

On the latter point, there may be a slow memory leak of some kind where a sip dialog is not being freed by drachtio in certain situations. I am trying...

I'm sorry, the template example config is wrong, change this: ``` 4096 ``` to this ``` 4096 ```

You can confirm by checking to see this log message when you start the server: ``` DrachtioController::run mtu size for udp packets: 4096 ```
