I suppose systems vary but I thought only the person receiving the
(second) call was supposed to hear the call waiting tone.  If both ends
got the call waiting tone then how would they know which one was
getting the call?  Of course switching in the tone may cause a loss of
signal to the other party even if they are not hearing the tone.  Does
it really cause loss of carrier on both ends or is the other end only
dropping out because the first one did?

I agree that the system hanging up on loss of carrier is important but
the usually the call is coming in on an attended terminal not a
system.  It is not necessary for the attended terminal to hang up on
loss of carrier, presumably the user will note this and hang up
manually.

I think it would be worth changing the 'disconnect on loss of carrier'
option at terminals if you are bothered by call waiting tones.  Of
course you are going to miss all those important calls...
