There is a network on Internet that could be moved -- https://hamshackhotline.com/ Here in Washington State there is a 44-net based system on Hamwan ( hamwan.org) A good project would be to setup an ENUM service to bring them together. https://www.voip-info.org/enum/

I don't know how wide its coverage is, but here in Europe we have a
network
of Asterisk PABXes on AMPRnet that have interconnecting trunks between

that allow you to call anyone on the network on their roaming number. Phone numbers are allocated based on the callsign (using a scheme based
on
the letters printed on DTMF keypads. based on my callsign, my phone
number
is 713210234253 for "1st letter on key 7, 2nd letter on key 3, digit 1,
3rd
letter on key 2, 2nd letter on key 4, 3rd letter on key 5" giving PE1CHL
).
The DUNDi trunk protocol distributes the information about the home
server
for each number across the network, so all Asterisk servers know how to route the calls.
It is easy to host a conference on one or more of the Asterisk servers
and
have everyone dial in to that. There is such a conference running on my local server where I have my IP phone connected all the time.
I think such systems can do low-bandwidth video as well, but I have never tried that. For audio it works perfectly.
We also have a network of PBX's tied together here in the US but using AREDN Mesh connectivity. Phone numbers are a flat 4-digits for local calling. For wide area calls, the person's (or service) 3-digit area code is prepended to the 4-digit local number. There are around 40 pbx's scattered around the world on this network. There is a White Pages directory to determine a person's (or service) phone number.
It would be interesting to try to connect the two systems together.
