Is there a way to filter out specific SIP messages?


I'm monitoring a Cisco CUCM for troubleshooting purposes. All I care about are call setup messages.

The REGISTER and OPTIONS messages are cluttering up the display, and I was wondering if I could filter those out?

OK, so if all I want to see are the INVITEs and the dialog that comes after them, I would use:

sip.Method != "REGISTER" or sip.Method != "OPTIONS"

@Cisco, I don't know much about SIP, but I think you meant:

(sip.Method != "REGISTER") && (sip.Method != "OPTIONS")

If you want to see them use:
(sip.Method == "REGISTER") || (sip.Method == "OPTIONS")
If you want to hide them use:
!(sip.Method == "REGISTER") && !(sip.Method == "OPTIONS")

Yes, I think the last comment is the syntax of what I was looking for. Thanks!

above ones are not filtering all OPTIONS and 200 OK response to OPTIONS message.

But below one is working for that.

sip && !(sip.CSeq.method == "OPTIONS")
