VoLTE and 3G shutdowns

@trainailleur said in PinePhone:
Is VoLTE support planned for UT anytime soon?
It was discussed on a Q&A a few weeks ago, and also on the Telegram Supergroup. We also have a thread about it on the forum here. The core developers are aware of the need, but support will probably not come soon.
Dobey mentions in the forum thread that getting to VoLTE will take significant work. Without meaning to put words in the mouth of the core development team, the chief priority of current development would seem to be getting to the Unity 8 cutover. After that is complete, many other things can be worked on, but there's no telling when VoLTE will get to the forefront of the priorities.
Fortunately, 3G retirements are not yet widespread. In the US, Verizon will be VoLTE only by the end of 2019, but other US carriers have longer timelines (2022), and while I've read of various Asian carriers wishing also to retire 3G, I don't believe that will be happening right away either.
What sort of things need to be done to get VoLTE support? How would I get started contributing to it?

I have moved the above three posts to this thread as they are better suited to here. They were not directly related to Pinephone but VoLTE in general. Thanks in advance for your understanding.

For those interested in the US situation, rumor this week has it that AT&T will open VoLTE to unlocked BYO devices by the end of this year in preparation for the Feb. 2022 3G shutdown.

Perhaps refer to @dobey 's comments above and reach out to him for details and direction. He knows infinitely more about the subject than I do.

Verizon will only support VoLTE within a few months.

Here's a discussion on carriers with known VoLTE compatibility for the pinephone using postmarket OS. T-Mobile, for example, was confirmed working by one person replying. Maybe there is hope? https://forum.pine64.org/showthread.php?tid=12560

@rik I think that's using phosh and modemmanager, which apparently has VoLTE working on pinephone already. Android based devices are different though.

Yes, certainly each modem has its own quirky codes. But it is interesting in that post that a command can be run to show what carriers are supported. I don't have a UT phone that supports 4G (yet), but if someone does, is it possible to run the nmcli command to possibly "sniff" what carriers are accounted for by the modem?
$ mmcli -m any --command='AT+QMBNCFG="list"'Does UT have nmcli available? I am not even sure....

Yes, but it does not have
mmcliwhich is for modem-manager, as UT does not use it. I don't know what the equivalent command to issue an arbitrary AT command to the modem would be forofono, which UT uses.
