the definite VoLTE deadline date in the USA is now known

@flohack Indeed, the IR.92 official document is composed of 76 pages.
Tried to read to understand the basics, but just gave up due to the complexity...

There are 193 official documents related to VoLTE...

Maybe years of migraines and white hair are ahead us...

@flohack Lol! I didn't follow all of that, but it did help. Thanks for taking the time to spell it out.

@Flohack So Pinephones and other open hardware projects, even non affordables ones, are the best way for the futur of UT and cummunity.

Now the question is when it will become a priority to have at least one full supported ? After 20.04 ?

For France, 2G and 3G coverage can be expected until 2030.

@keneda The beauty of the Pinephone is that its IoT modem can handle VoLTE in the firmware, but this modem has other challenges as we know, and its questionable if that is a way forward for all user needs. We still have to solve stability and energy efficiency on this platform, and without the help of the Pinephone community and PINE64 this likely wont be easy.

I cannot say what we will do after 20.04 but this is still so huge that we do not start worrying today, sadly. 20.04 will keep us dramatically occupied, unless we find a way to share the work better with the community devs, a problem unsolvable it seems.

As 3G will shut down in more and more countries, having VoLTE working wil be mandatory for more and more users.
And as you seem to say VoLTE will be years in dev time to work on halium devices... I see only one solution in meantime ^^

As you may know already i'm not in trouble with 3G myself, but i know if i was and need it and no UT phone having VoLTE, i'd go back droid...

You do your best with ressources you have at UBP and that's all matters.

@flohack : I understand that the move to 20.04 is a number 1 priority, and that there are no volunteers with dev skills who can work on VoLTE support now. But VoLTE support seems to qualify for a shared number 1 prio. If UT doesn't offer VoLTE soon, at least part of its users will have to leave UT because of their network providers switching off 2 & 3G (and sooner or later this will be the case everywhere). I guess all alternative mobile OS'es are facing the same challenge and need to find a solution a.s.a.p. Wouldn't it be possible to set up a 'consortium of alternative mobile OS'es' to work on a solution (for VoLTE, and maybe e-sim and other challenges too) together? And if there are no volunteer devs, perhaps start a funding campaign to hire devs. I saw that Redhat also offers software solutions to providers to offer VoLTE. Maybe such a company would be a good partner? Also, a 'consortium' could perhaps persuade phone manufacturers to cooperate in development, because the combined OS'es together represent a bigger user group than they would alone.

@alter
First of all sharing priorities is not really a thing when you don't have enough manpower.
Than the foundation HAS to go to 20.04 before anything else because the changes brought by 20.04 can change how to make other things work (e.g. VoLTE).

Such a consortium exists (sort of) and that's the Ofono project:

Also you can read the plan for UBPorts there:

Be sure that everyone is aware of the urgency and of the consequences related to VoLTE

@applee : Thanks for pointing this out. I wasn't aware of this.

@alter My pleasure.
