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.
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.

and not in the downlink.

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