I'm not sure what you mean with the last sentence...
I tried to connect to my Asterisk via LAN or via DSL (either via LTE or 
other DSL).
Then I noticed that if I call another peer in same network (= both peers 
via DSL or both peers in the same VLAN), the quality is very good, 
otherwise is very poor.

But why should Asterisk have problem if the peers are in different 
networks it's for me a really big mistery...

This evening I'll try to capture the pakets in a call between two peers 
connected to Asterisk via LTE, two peers connected in the same LAN and a 
peer connected via LTE and the other in LAN, then maybe it's possible to 
find the problem...

But if you have any other idea, I'm very happy to hear it! ;)
