Dear Ethereal Users,

first of all merry christmas and happy new year to all of you!

I believe I have a simple problem but unfortunately I could not find any solution to it in the FAQs. I am a beginner with Ethereal and therefore would be very grateful for any help you can give me. With Ethereal I capture the real time traffic of voip calls through the net but I am asked to  display just a few voip-relevant steps. These should be the ones showing the following protocols in the "Protocol" column: SIP, SDP and DNS. How can I get the ethereal filter to show me (display) just these protocols when I start capturing the real time traffic during the procedure of a VoIP call.
I would like to thank you in advance!
