Hi Harris,

I tried without "-R h245" flag and with "-V" flag. It can print the protocol tree of other packets, including H.225RAS and H225Q931. But for H245, it shows Data(XX bytes) like below.

Thanks & Regards,
Luke

What happens if you run

	tethereal -r c:\temp\call -V

*without* the "-R h245" flag?  Does it print the protocol tree for 
H.245 packets?  Does it print the protocol tree for the other packets?
