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
Voice only analysis
The following screenshot shows network-traffic (in Bytes/s) for the following connections:
- Black: traffic from and to Trixbox #1
- Red: traffic between the 2 Windows machines running X-lite
- Green: traffic between laptop #1 and its Asterisk
- Blue: traffic between the two Asterisk PBX's
- Pink: traffic between Windows machine #1 and its Asterisk
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.
