[Qualcomm} VoLTE call for testing

mariogrip

@Lakotaubp Haven't tried on my FP4 just yet, but its on my todo list.

mariogrip

@Beta-Break It will say 5G and VoLTE in the indicator

mariogrip

@kristatos

Nope
I haven't tested it yet, but it should
Mtk has its own plugin, it should already be in devel and enabled on the newest volla devices.

@mariogrip, maybe change the title of the topic to indicate that this is only for Qualcomm devices?

mariogrip

@Enrico13011978 You need to ask the porter of the device to enable ims and this plugin.

mariogrip

@peat_psuwit done

@mariogrip
Does that mean ims messaging (RCS) could be possible on UT ?

mariogrip

@Inali Awesome! Here is how to enable it.

be on the latest devel (rev 30)
Install ofono-binder-plugin-ext-qti (using apt)
Add this extPlugin = qti to /etc/ofono/binder.d/qti.conf

Here is how the full file should look like

phablet@ubuntu-phablet:~$ cat /etc/ofono/binder.d/qti.conf 
# This device do have 2 slots, but the other is eSIM only and we currently do not have
# a way to install or modify those
[Settings]
ExpectSlots = slot1
extPlugin = qti
radioInterface = 1.5

[slot1]
path = /ril_0
slot = 0

Then reboot

@mariogrip Thanks Marius

@mariogrip I will give this a go, but I noticed something first...

I already am on devel, and today I put in my SIM card (I am in USA with TMobile) and I noticed my Fairphone 5 will drop from 5G to "L" (which I assume is short for LTE) during calls and calls work. Is this a fair assumption that VoLTE is already working? The switch in the carrier settings is already enabled.

This was all without me doing anything aside from updating to the devel branch. Why does this work without your additional above instructions?

Either way, great work so far!

EDIT: Forgive me, maybe the interface glitched. I see it shows 2G when in calls. I will try the above instructions.

@mariogrip I copied the configs from the FP5 gitlab from about 24 hours ago and that got LTE working, when I tried calling the cell icon didnt show it dropped out of LTE, to install ofono-binder-plugin-qti is there a link or something to install it? Im bit rusty on some of this.

edit: I tried to install with apt as I saw you mention that in another post but it gave me an error saying it couldnt find ofono-binder-plugin-qti

On another note, glad to have ya back, missed ya

I used UT Tweak Tool to unlock the system to be writable, then ran "sudo apt update" to update list of apps, then installed ofono-binder-plugin-qti, then modified the file as stated, then rebooted to reapply read only.

@Inali this is what I keep getting after I do a apt update then try to install

root@ubuntu-phablet:/android/vendor/lib64/hw# apt install ofono-binder-plugin-qti
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package ofono-binder-plugin-qti
root@ubuntu-phablet:/android/vendor/lib64/hw#

EDIT:

I just figured it out, the package is ofono-binder-plugin-ext-qti Ill test it now

I have tried this and it appeared to work for VoLTE calls briefly. Sometimes I could see the VoLTE logo, other times it was not there. I only called my voicemail so it wasn't anything ground breaking.

Also after an hour or so (or when I noticed) my SMS stopped allowing texts to send completely and only received texts if I toggled Airplane mode on and off for some reason, and reverting the steps to disable VoLTE did not fix this. I am unsure how or why this happened or if it is relevant, but absolutely nothing else changed on the phone since enabling VoLTE per the instructions since I was using the phone purely to test this feature.

I ended up wiping the device with a fresh copy of dev channel v30 image and immediately enabled VoLTE again with your instructions. I will put my SIM back in the Fairphone 5 tomorrow as I need it to work at home for now

I will keep everyone posted.

Thank you for your work.
I will try to test it on xiaomi mi6. Use a China Mobile SIM card. After I successfully upgraded mi6 to 20.04.

@mariogrip Thank you very much, I will do that.

@mariogrip i understand that ,the message you posted is specially for porters of other devices .They have to put their effort to make the devices work in VoLTE.We have to wait for them to finish it.Thanking you.

@mariogrip could you please explain a bit, the different settings in qti.conf, for porters of other devices?

For example the "radioInterface" number, what is it and is that device specific?
How is the syntax for two slots in "ExpectSlots", slot1,slot2?

Then, for activating, I suspect OfonoPlugin: binder must be set in deviceinfo file.
What about OfonoImplementsIms? Is that needed in any way? From the MR, I understand, that it activates/displays the VoLTE switch in SIM-settings, but at least, it already gets displayed without the deviceinfo setting.

And, what are the first places to have a look, when using the ofono-binder-plugin and nothing works?

Thanks and best regards,
Lukas

As of this morning, I have tried dev build 33 with this VoLTE config.

If I call my phone number with a different phone, my Fairphone 5 will open the dialer immediately and show that it is trying to call the incoming caller, but nothing ever happens. It will stay on this screen forever even with airplane mode on. I am forced to pull the battery out. (shutdown and reboot no longer work on the phone, both show a black screen and the power button is unresponsive.)

I have noticed although I have full bars for 5G and LTE, the phone will frequently drop to LTE.

I have also noticed that the VoLTE logo constantly disappears. I saw the logo saying VoLTE, made a test call, noticed VoLTE was gone, and my signal instantly went to nothing as this test area has no 2G coverage. The call then is frozen on, even if you close the dialer and I again am forced to remove the phone battery since I cannot shutdown or reboot correctly.

Hopefully these tests mean something to you are are helpful.
