A large number of the systems either have a star, planet, or other really large object at the center, so there aren't a lot of places to test at. I suspect folks sitting on Toledo would be able to hear each other, as well as anyone on the Isis, but the folks on the Isis would not be able to hear themselves or the folks on Toledo...
Or am I way off on this?
Now that I think about it, if everyone who is docked is suddenly at 0,0,0, wouldn't you be able to hear people from any base in the system? Hmm... Testing is in order...
Edit: <annoyed grunt> Didn't realize the server was down...
