I’ve a question: How can I dis/enable caller ID on the L5.
My old nokia N9300 has this setting available in Phone Settings.
I miss this setting on the L5.
I tried to use USSD codes, but they don’t seem to work on the L5.
There are codes that are not technically USSD codes that are standardized but which may or may not work (on the Librem 5).
There are codes that are USSD codes and these are not standardized (i.e. vary between network operators) and which may or may not work (on the Librem 5).
The above page specifically notes that for the “not technically USSD codes”, they are interpreted first by the handset. So I would suggest that the problem here is that Calls doesn’t have (all) the necessary functionality.
Based on the other topic linked above, I should say Callsor the modem.
“they are interpreted first by the handset” doesn’t specify exactly where on the handset i.e. the division of labour i.e. application software and other software on the phone itself v. firmware in the modem.
That isn’t accurate because some codes that are called USSD codes are not USSD codes and because being handled on the handset could mean in the modem but could mean on the host CPU.
I’ve checked the USSD page of my provider (Fonic in Germany). They support the following codes related to switch-off call transfer:
deactivate on no answer: ##61#
deactivate on not reachable: ##62#
deactivate on busy: ##67#
I tried them all with the Call app. After entering the above code and pressing the dial button, a new window appears labeled USSD and a rotating circle, but no other message or visible reaction. But it seems that the switch-off in the network worked.
