[Qualcomm} VoLTE call for testing

domubpkm

@kristatos I contacted TheKit (volla team) : if i understood well, it is currently No for the Volla (halium 9), Yes for the Volla 23, Yes for the Volla 22 (halium 12), maybe for the Volla 22 (halium 11).

kristatos

@domubpkm Thanks, even if this was not the answer I wanted to hear
But for me it's not such a big deal like for other users, cause I'm located in Germany where 2G will be for a long time.

@messayisto does not have to be, its the device i have used to develop and test volte for Qualcomm so i know it works. For other devices it might require some work to get it to a new device.

mariogrip

@tigerpro Yeah, at least LTE has to work. To test it, install ofono-binder-plugin-qti and add extPlugin = qti to binder.conf or binder.d/something.conf under [Settings]

Example from FP5

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

Also remember to re-enable ims services that might have been disabled under porting.

mariogrip

@alagirialagiri They need to be ported to be able, see my comment above for instructions.

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

Keneda

@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.

tigerpro

@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

@mariogrip

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.
