In Asterisk SIP Settings, try setting Local Networks to:
192.168.10.0 / 24
111.111.64.148 / 30
111.111.3.10 / 32
After changing these, restart (not just reload) Asterisk and test. If no luck, post a new SIP trace.
Doing this kind of stuff with a relatively ancient Asterisk without pjsip is tough, because you can’t set up different transports for the networks.
