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Telephony, VoIP Calls, the GRAPH button has been replaced by a FLOW button.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:
