I think, the problem with bad quality and broken voice just happens if
the peers are in different LANs, since if I call my wife's phone (VLAN
"phone") using my mobile phone via SIP (in VLAN "intlan") the quality is
bad, but if I call her using my phone in VLAN "phone" or if both peers
use SIP via LTE the quality is very good...
Could you suggest me something to restrict the problem?
Currently, I think the problem can be:
1) on Asterisk
2) on my Gateway/Firewall
At home I have many VLANs, that normally *not* communicate together
(some exceptions are of course implemented). The phones don't reach the
Internet via NAT (VLAN "phone" has no routing in Internet).
The mobile phones are in VLAN "intlan", with routing in Internet.
