Well, that's the very problem...
I don't know *how* to analyze it... Or, better, how to read the data...
I know, I can use tcpdump, sngrep and many other tools, but I don't know
what I have to expect and how to decide, that a paket is wrong...
Can someone help me to learn it?

Of course, the first thing to do is to locate the problem...
I think, the problem can *not* be:
1) by Deutsche Telekom (since I have the problem even on local tests)
2) on the devices (since I tested many devices)
so the problem can be:
1) in the Firewall configuration
2) in the Asterisk configuration
3) in the BananaPI
I think I can exclude my switch, since I checked right now and no port
Now the question: can someone help me to understand/learn how to check
the involved parts and search for the problem?
