Hello, I only need to capture SIP packets. Would you please tell me how to configure Wireshark to accomplish this? It's better to use pictures to describe to me. Thanks.

I have tried the sip, udp, ip, port and ethernet as follows show. Only ethernet can capture SIP packets but this is not my wish. My wish is to use sip filter to capture all pure SIP packets. alt text

Dear Cmaynard, I mean how I can only capture SIP packets by wireshark? I have tried to configure the capture filter of the capture option but it's unavailable.

I don't understand what you mean by, "it's unavailable."

Maybe you're having trouble with capture filter syntax? Capture filter syntax is not the same as display filter syntax. Have a look at the Capture Filters wiki page; maybe that will help you.

The SIP wiki link posted by @cmaynard states:

Capture Filter

You cannot directly filter SIP protocols while capturing. However, if you know the UDP or TCP or port used (see above), you can filter on that one.

Usually SIP is on UDP port 5060 (though sometime TCP port 5060 is also use)

So just use "port 5060" in your capture filter, and the use "sip" in the display filter to filter out any non-SIP traffic that might be on that port
