Yes, that’s how this works, and it uses SIP.
The boxes all basically turn the cell lines into SIP trunks, then they’re used for grey routes for international VoIP providers to dodge termination fees into the target country and get cheaper per-minute rates, because the game of pennies really adds up in telecoms traffic.
Ah I see, "grey routes" makes more sense
