	. . . Long distance trunks all have devices called echo
	suppressors.  These disable transmission in one direction
	when something is going in the other.  Without them, your
	voice would bounce off the other end and you'd hear it a
	second later. . . .

And if you don't beleive this, you should try talking on a
long-distance line on which the echo-supressors are malfunctioning!
I had this happen once, and found it very disconcerting. Sort of
like having a short-circuit in the brain. It becomes totally
impossible to hold a conversation.

I'd like to have something to intentionally cause this sort of
echo, so I can switch it on when I get a call from a particularly
obnoxious phone salesperson.
