So, now I know what was the problem and I solved it...
The problem was: the Banana PI... :(
I checked it with mtr and I see really bad times to communicate with
other devices im same networks (~2 - 380 ms!!).
Many tries with other Switch ports and so on didn't solved the problem.
So I bought a mini PC and I configured it as Firewall with Asterisk.
mtr give now really good times (~0.2 - 0.4 ms).
And Asterisk works very good...
I tried right now with my father in law and the communication was
excellent, without any disruptions.
So, I really thank you for the idea, that my Banana PI can be the
problem. It was! ;)
Have a nice weekend!
