I have the following setup:
PBX Server -> Internet -> LAN -> IP Phone -> Workstation (PC)
Which means that my computer is connected to the LAN, through a Dual Ethernet card on the IP Phone.
I would like to analyze traffic between my IP Phone and the LAN during it's normal operations (incoming / outgoing calls, text messages, web interface actions...) which are all handled by communication with the PBX.
The answer I look for would:
- Be as much to the right part of the above chain as possible. Directly dumping from my workstation would be the most prefered if there's a way, dumping from the PBX server the least,
- Optionally provide extensibility for traffic injection.
I have full physical and administrative control over the entire setup, so putting a server somewhere in between is an option.
