Hi,

 This patch adds the barred dialing support. If Barred Dialing service is
enabled, then oFono will go into emergency mode. Patch has been tested with the phonesim.

Hi Jeevaka,

I have a few comments on the support of FDN and BDN in Ofono. Can you please
clarify.

Thanks,
Sankar.

Is there a way for the clients to enable or disable the Fixed Dialling? I
assume they should be able to do this by using the dbus calls,
"LockPin/UnlockPin".  Is there a way to store the FDN numbers in the sim
card? How does ofono validate the request to be passed to the network when
FDN is enabled? Looks like as per the current implementation of FDN, only
emergency calls are allowed. But as per the 3GPP standards, calls shall be
allowed to any number (irrespective of emergency no) that is part of the FDN
list.

If the modem remains in PRESIM State, how does the mobile receive the
Incoming Calls or SMS? As per my understanding FDN applies in the uplink and
not in the downlink.
Please clarify if my understanding is wrong.

I have similar doubts for BDN also.

Currently, there is no way to enable or disable fixed dialling or Barred
Dialling using oFono. If my assumption is correct, there is no plans to
add support.(Denis/Marcel can confirm this). oFono doesn't support
storing any numbers in the SIM storage(EFadn, EFfdn or EFbdn). Agreed as
per the specification calls shall be allowed to any number that is part
of the FDN list. But its been agreed that oFono will enter presim state
when FDN or BDN service is enabled in which state only emergency calls
are allowed.

Yes, your understanding is correct. FDN applies to the Mobile originated
calls, SMS etc.

Then as per your email, the support provided in Ofono seems to be limited.
If there is no enable or disable is allowed,
I am not sure, how we can we have a card in which FDN enabled, which will
force the ofono to enter presim state. Unless there is no
option to disable at, forever with that sim card, the phone will be in
presim state,leading to only placing of emergency calls.

Thanks for confirming. Then in this case, are we not forcing the mobile to
go in a state, where if FDN is already enabled in the sim card( may be from
a different phone), user allowed with no option rather than making an
emergency call.

Support for disabling FDN was discussed earlier. Denis/Pessi could you
confirm what was the decision made on FDN disable support?

Yes, we are forcing the mobile into presim state where only emergency
calls are allowed. We have already discussed this many times in irc and
its been agreed that only emergency calls are allowed when FDN or BDN
enabled SIM used.

Can you please provide your comments on the support for Enable/Disable of
