Hello, I am able to see ISUP (M3UA) in the call-flow diagrams in last versions of wireshark 2.x. Same capture is being shown properly in versions 1.12.x. Do I need to configure anything special or is this a bug? Thanks. Regards. asked 22 Jun '16, 10:17  juamargon |
One Answer:
The M3U sample found on https://wiki.wireshark.org/SampleCaptures works fine with Wireshark 2.0.4 and 2.1.0 development release (the VoIP flow graph being much nicer with 2.1.0). Which version of Wiresahrk are you using? This used to be a problem with the first 2.0 releases but should be fixed now. If not, could you share a capture file? answered 22 Jun '16, 12:01  Pascal Quantin |
Hi Pascal,
Thanks a lot for your answer. I have checked the sample capture and it works fine in version 2.04. The flow in shown with your parameters. But it is not working with my traces.
Unfortunately I cannot share the traces I am working on, but to let you know the differences, to decode my call I need to configure MTP3=ANSI and M3UA=RFC4666.
The ANSI messages are correctly decoded, but when trying to see it as a VOIP call, it is not detected and the graph cannot be shown.
This works properly in version 1.12.4.
Without any capture file, we cannot fix the issue. Be aware that a bug can be submitted as private, which means that only Wireshark core developers will have access to the attached capture. let us know if this is acceptable.
