I am attempting to monitor sip packets between the sip server/VoIP phone system and a sip to analog gateway. When I connect using a USB to Ethernet adapter I do not see sip or icmp messages. When I use an Ethernet port on the same pc and make no changes to Wireshark except to change the interface I see sip and icmp messages.
