Is it Possible

Anonymous's picture

Dear All,

I have Wireshark installed on my PC. Connectivity is like Switch -> IP phone -> PC.. I want to capture the packets of VOIP communication. In wireshark, while capturing, it will ask us to select the interface option is PC NIC. In this case is it possible to capture the VOIP communication..

Please port your input / suggestions.
