Hi, for some reason Wireshark doesn't capture SIP messages even when I'm leaving the filter empty.
It is also configured to capture packets in promiscuous mode.

I am using SIPp (version 3.1.1) to generate the SIP messages.
SIPp is a program that can generates SIP messages and check that they are being received.

I'm running SIPp in two separate shells, one that runs a default client scenario (uac) that generates INVITE messages,
and in another shell a default server scenario (uas) that receives the INVITE and confirms them with 200 OK responses.

Here is the screenshoot of the client:

Here is the screenshoot of the server:

As you can see, the client sends INVITE messages and receives 200 OK responses from the server,
and the server receives INVITE messages and sends 200 OK to the client.
So the problem is not with the sending/receiving of the messages but with wireshark.

Do you know what could be the problem and how to fix it?
Thanks
