Right.

Oops, correct. I fixed that, thanks.

No, incoming call will frequently be sent until either you accept or release 
the call.

The status signals are only for calls that have been actually established.
Which status signals you can expect unfortunately depends on the capabilities 
of the modem. Some modems have fine granular call progress status 
indications, some not. We can only guarantee a few critical status 
indications, but the ones "in-between" will have to be optional.

IIRC "Disconnect" is one of the optional status signals. We will only 
guarantee that you get the ReleasedCall signal.

Not yet, as you can see I just have started documenting the API -- my order 
is:

Device (done)
SIM (almost done)
Network (not started yet)
Call
Phonebook
SMS
GPRS

So, 'Call' will be there soon, hopefully by Monday or Tuesday.
