From the graph shown above there can be concluded that indeed the two X-Lite machines are only connected to their own Trixbox, i.e. there is no ''direct'' traffic between the two X-Lite machines.

Ethereal is used to analyse the network traffic.

We captured the network data with the following machines: 

192.168.1.101 - Asterisk #1
192.168.1.106 - Asterisk #2
192.168.1.3   - Windows machine 1 (also running both VMware's for both Trixboxes)
192.168.1.189 - Laptop #1 running only X-lite

After capturing we filtered out other data to machines not on the local network (IP-adress other than 192.168.1.x), using this filter: 

ip.src >= 192.168.1.1 && ip.src <= 192.168.1.255 && ip.dst >= 192.168.1.1 && ip.dst <= 192.168.1.255

We did also do some Ethereal Analysis on the traffic during several conversations.
