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.
Voice and video analysis
Schematic sketch of the situation:
In the screenshot below, the following events were measured:
- @4 sec: Video was turned on
- @14 sec: Video was set to black (connection lost with DVdriver)
- @20 sec: Video showed moving pictures again.
Legenda:
- 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
The following graph shows the traffic is almost constant. Till 35sec the conversation included audio and video. The rest is audio-only.
This measurement shows there is no traffic between both SIP-phones, only via (both) Asterisk PBX.
