Steps to reproduce:
Load the attached capture file.
Telephony > VoIP Calls > Flow.
The flow shown in 1.7.1 is not correct in the sense that some T38 elements are
missing. It seems that only the direction from 10.72.0.14 to 10.72.0.22 is
shown.
This is a regression in 1.7.1 as compared to 1.6.7.
See screenshots.
