The usability problem I can see is: if the secretary cannot hear the caller,
she/he cannot avoid talking on top of the caller, and the boss could get
both talking at once, not hearing either properly.

It almost sounds like you want to just silently put the caller on hold and
link the boss with the secretary in a normal call. Then when the secretary
has finished, reconnect the boss with the caller.

What I think is a more useful whisper mode is where the whisperer can hear
both sides of the main conversation. I still don't know how to implement it;
I think you would first have to make changes to the conference summing code
within zaptel.c, which is REALLY hairy!
