Yes, an ADMD in Country A can be connected to a PRMD in Country B, and
transfer directly to it, if the rule sof Country B allow it.  This is a
local matter under the CCITT recmendations.

In reality, it is happening, and will be impossible to prevent or or
even to monitor.

I am not sure what you are asking here.  Can you expand on it?

Yes, as noted above, it is not preventable, and it is happening.
