How to make two calls with one phone?
With a BT (sorry) headset that you normaly like to use
with your phone and that you have with you.
So when you will share your phone with another person,
one of you will get the bluetooth headset
- able to pick up calls and maybe use Speech recognition
on the asterisk server (not phone) to use dial menue
and to dail out (but has to stay in the radio range
of the phone)
the other could use the phone as normal.
It would be thinkable that during a phone connection with
your asterisk server, you could transfer this first one to the headset
(switching down the codec rate?)
and free the phone for a second phone connection.
Because using a data-call - the second phone connection to
your asterisk server will not cost more.
So when you walk with you partner and get a call that will take a
little bit longer (and bores your partner), she could phone, too,
or use 5 kbit/s data connection inbetween.
(with compression and using a text webbrowser like elinks on a
server would reduce traffic, too).

Maybe not the best box for encrypted phone calls,
the ethernet driver is not yet open source.
