Hi John, True, but 'AIOP' doesn't have a very good ring to it really. Think we should stick to D-Star-VOIP or DV-Voip. We know what we mean, but outsiders will just think we're adding confusion to their systems in reality. 'Hotspots' directly inject the AMBE voice through the pipe, along with the routing info to the reflector or wherever, not totally sure as not played with the complete 'hotspot' yet, IE callsign routing etc. Still, its all good fun and a learning curve for some of us! 73.
