I'm in the military. I have found that the habit of saying "over", learned as crowded circuit management for open radio circuits, is quite useful in teleconferences and VTCs, and for similar reason. It makes it clear that you're handing over the circuit. "Out" means you're leaving the circuit.
I think that can work well, as long as people also adopt the military/aviation habit of speaking crisply and not rambling on to hog the channel until they're absolutely sure they've emptied themselves of every possible thought they could ever have on the matter. Like I just did with every word after "rambling on". ;)
Yeah, this. The experience with overseas calls I was referring to was talking to my then-girlfriend who was spending a year studying in France. Saying "over" all the time is not very romantic.
On the amateur radio side you see both types mixing in pretty amusing ways. On the one hand there's contesters and dx-ers that are all about confirming contacts as fast as they can, and on the other there's more casual people that'll talk about anything and everything that comes to mind. In my experience both sides use some amount of procdural language, but at very different cadences.
