Hi Martin,
I'm an Avaya tecnical eng, I'm testing the Ethereal over my PC IBM T21 W/2000. I made a call over IP using the IP trunking between Avaya switches. What I suppose to see is the Q.931 message on the capture messages but I don't see Q.931 messages.
Thanks

Are you sure it's H.323 traffic? There are some other protocols used for VOIP also.
Is the computer where Ethereal is running connected to an IP switch and the H.323 signalling going
between other computers in the network or could there be any other reason why Ethereal cannot
cpature those packets?

Is the H.323 signalling loop-back on the computer (cannot be captured on some OSes)?

Are you using some capture filters or display filters?
