Do not report early incoming calls.
Report "disconnected" state separately.
Call ofono_voicecall_disconnected() only after call id is released.

There were some cases where Dial returned an incorrect call object,
e.g., after oFono crash and recover.

So I'm guessing that you're restarting oFono and get
ofono_voicecall_notify events without setting dial_result_handled properly.
Do you think it is a better idea to resurrect the old list_calls driver
method and fire this off explicitly when the atom is registered? The
callback can then take care of setting dial_result_handled appropriately.
Regards,
-Denis

That is one possibility.The belt-and-suspenders approach of
prepare_to_dial() makes oFono more robust in case there is someone
talking directly to modem behind oFono's back, however.

This is not a case we support or will ever be willing to support in the
core anyway. oFono performs too many optimizations internally and the
assumption is that oFono has exclusive control.
Which brings up a question, do we even want to bother performing crash
recovery or simply stipulate to the modem driver that the state should
be reset completely in case oFono crashes? Remember that crash recovery
involves sim toolkit, voicecalls, gprs, ussd, etc. It is pretty much
impossible to handle this properly...

-Denis
