This capture seems to contain only the communication between the 3CX Client and the 3CX Server. Anyway though, as the issue is related to the actual audio not working, the RTP packets would have to be included as well, as a txt file would not be enough.
I read through the whole post and I think I am missing something. It has been repeatedly stated in this thread that the ports that have been opened are 9000-9015 and the Firewall Checker passes. The firs time I though it was a typo, but I have seen it a few times.
Now unless you are using an older version prior to V15, the default external audio ports that need to be opened are 9000-9255 so unless you open the whole range, you will have problems.
If you manage to get a packet capture with a full call (start to end) with no audio from the 3CX Server, that could enlighten us more. Also, from what I can tell under Settings --> Network, you have set the PBX to "Dynamic IP". If you can, set this to Static, fill in the correct Public IP and restart services.
