Subject: [Wireshark-users] VoIP calls GRAPH button gone. FLOW button shows SIP but not RTP or T.38

I just installed Wireshark 1.4 on WinXP. Under Telephony, VoIP Calls, the GRAPH button has been replaced by a FLOW button. The ladder diagram produced by the FLOW button includes the SIP and RTP, but not the T.38. How can I make the ladder diagram display the T.38 as in previous releases of Wireshark?

This sample has 352 T.38 packets, comprising an entire fax call:
