Please don't use glib types in public API.  Use ofono_bool_t here instead.

It seems we might need more information here, in particular the phone
number being dialed by STK.  I don't see how we would obtain this
information otherwise.

Also, since emergency numbers can be dialed by STK, we probably need
special logic for inc/dec of emergency counters as well.

I don't really like this, is there a way we can re-use the dial_req
structure, as that one already contains the message, icon_id and phone
number members we need.

This situation is quite funny, I'd almost rather crash here, but fair

Are we getting information on the terminal responses sent by the modem
for these?  I'd rather handle this sort of stuff by parsing the terminal
response than relying on the session end notification.  This might also
help alleviate the concerns Andrew has raised as well.

This part seems fragile.  A new command may arrive and the alpha id
and icon id won't be cleared.  Additionally modem_handled_cmd is not
reset when the pending_cmd is cancelled so it may affect a future
command.  Maybe voicecall.c should automatically clear the alpha &
icon id after the first new call?
