Uhhh. It's been a long time since I worked on such a system (1975 I

That was 1975. The only people who ever were exposed to any propigation delay
where those rich enough to make a long distance call that was routed over
satellite. If I remember correctly it was about $5 a minute to call New York
from L.A.

This is 2011, everyone is used the the propigation delay of digital telephones,
and VoIP. 150ms is tollerable.

For you, perhaps. I have a mild learning disability and I can't use the
phone if there's too much hesi............tation. I have a twisted pair
that connects directly to an EOC at the push of a button. SMS works
great for me.

What's really funny is "music on hold" via mobile voice circuit.
