I called 102 from 101 successfully! I have everything connected to my home router. Asterisk is running on tleilax, so I used my Android phone to call doge. Worked like a charm.

I’d been thinking that the firewall was blocking connections, but not at all.

Anyhow, thanks to everyone who’s help me out. I’m sure I’ll have other problems, but huge milestone.
