I discovered today that, Wireshark 1.8.6 does not display RFC2833 DTMF telephony events in VoIP call graph analysis anymore.
It was a very convenient way to see, which DTMF digits are transmitted in the RTP packets.
This example displays 7 DTMF digits and is taken with wireshark 1.8.3. The same trace shows only "RTP (telephone-event)" and not which digit is transmitted anymore as of (at least) wireshark 1.8.6. Which digit is transmitted, has to be figured out at the packet view.
Is this a bug or may be enabled by a new option?
Thanks & Greetings, Chris

That behavior changed between 1.8.5 (shows DTMF event info in graph) and 1.8.6 (does not show DTMF event info). Looks like a bug to me.

This a regression tracked by bug 8610 and now fixed in the soon to be released 1.10rc1. The fix will also be backported in 1.8.7 and 1.6.15 releases.
