I found this on the wiki site and need a little further help interpreting:

 

“Q: What is a good filter for just capturing SIP and RTP packets?

port sip

should capture both TCP and UDP traffic to and from that port (if one of those filters gets "parse error", try using 5060 instead of sip). For SIP traffic to and from other ports, use that port number rather than sip.

For RTP packets, you would have to determine one of the port numbers that would be used, and specify that port number.”

Here are my questions:

1.      port sip is what I need to type into the filter space to get SIP traffic right?

2.      It says I have to determine one of the port numbers for RTP, it uses several port numbers, will just specifying one of them pick up the rest of the RTP traffic?

3.      So now what is the full syntax that I would type in the filter box to answer: “What is a good filter for just capturing SIP and RTP packets?”

 

Thanks
