The audio for a GSM cell phone is only recorded at 13 kbit/s or less and latency is not really going to perceivable even on a satellite connection. Just in travel time alone to the farthest you could travel on earth your latency would be 101 ms + equipment latency + any satellite latency. No matter where you are the latency should be under 1 second so it will basically not matter. -- Democrats are not Socialists any more than Republicans are.
