Find attached a couple of changes for t38: - Use the dissector to reassemble t30 frames - Dissect t30 protocol - Move the "Fax t38 analysis" to the "VoIP Calls". Now when selecting "Statistics"->"Fax t38 analysis" option, there is a message that redirect the user to use the "Voip calls" instead. We may keep this option for one release, and then remove it ? - Added in the "Voip calls" the ability to detect a t38 call if there are not signaling associated with it. For example, when using "Decode as.." to dissect t38 packets, it is possible to use the "Voip calls" to analyze that call. - Display "SDP (t38)" in the "Voip calls graph" for SDP t38 sessions.
