Jaap Keuter 815a4af69e Hi All,
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.

Regards
Alejandro Vaquero
