Are you sure of the name of the rom?
Enter the string * # * # 86583 # * # * in the field for dialing numbers, a message will appear after the last character, which must end with DISABLE. If ENABLE, we repeat the string again. This will allow VoLTE because this menu is hidden by default.

As said on my previous post, there is an error in the name of the rom.
It is your provider that transmits to Xiaomi the necessary information for the activation of the Volte/vowifi, either you use a stable Beta, or your provider has not yet transmitted the information.

I have just checked and it seems to be a stable beta, I haven´t joined any beta channel or anything, it was just another OTA update. First time it happens, I guess I better wait for the final release and see if that gets fixed.
Thanks for your insight.
I´ve found a fix:
Go to settings > Sharing & Connections > Restart Wi-fi, mobile networks and bluetooth. After this is done you dial back the VOLTE and VOWIFI codes and restart the phone. FIXED.

After over a week of trying, I've come up with a solution to enable WiFi Calling (probably also VoLTE) in Fulmics ROM for LG G6 and probably G5 running any stock based ROM.
THIS GUIDE WILL ONLY WORK IF YOUR DEVICE IS ON THE LIST OF YOUR CARRIER'S VOWIFI/VOLTE SUPPORTED DEVICES AND THE SERVICE IS ENABLED THROUGH AN OTA UPDATE FOR YOUR STOCK, BRANDED ROM PROVIDED BY YOUR CARRIER!
I don't believe in magic, you shouldn't either so don't think this guide will make VoWiFi/VoLTE work on your device regardless of your carrier's support for your phone model.
Also, if your provider offers VoLTE/VoWiFi through an external app available in Play Store, don't bother reading any further.
General idea described in this guide is to tweak your rom in a way that it is recognized by your carrier as their own VoLTE/VoWiFi enabled build that has a "green light" for IMS and Xcap apns registration in your provider's VoLTE/VoWiFi service. During my attempts you make the service work on my G6 running V10t based Fulmics ROM i discovered that adding IMS and Xcap apns plus getting all the IMS and GPRI VoLTE/WoWiFi hidden menu settings right is not enough. I had everything set up right and still couldn't make a WiFi call. Then it occured to me that maybe i can't make it work because Fulmics ROM is based v10t, and my provider's VoLTE/WoWiFi enabled rom is the v10h? So i tweaked Fulmics 1.6, then 2.0 so it masks itself in front of my provider as v10h while in fact it still is v10t Fulmics ROM 2.0. And guess what... IT WORKED!!! My Carrier's IMS and Xcap apns, manually added by me to the default open-eu apn list storred in /system/etc/apns-conf.xml, got registered in the service activating WiFi Calling on my device.
How to do it step-by-step guide below
1. PREREQUISITES:
- /OP/[YOUR CARRIER'S CUST FOLDER IN XXX_XX NAME FORMAT] in your main dir /root. If you only have OPEN_EU in your /OP you must get your carrier's specific cust folder or install Fulmics over your carrier's VoLTE/VoWiFi enabled rom then the cust folder you need will appear in /OP
- build.prop file from your Carrier's VoLTE/VoWiFi enabled rom for your LG model (make sure following line is in the file: ro.lge.cupp_capss.rootdir=/OP
- /OP dicectory in your device main root directory with your carrier's VoLTE/VoWiFi enabled ROM's subfolder (XXX_XX format). OPEN-EU or
GLOBAL-COM are not the ones .
- files from your carrier's rom: /root/data/ipsec/wo_apn.conf, /root/data/ipsec/wo/apn_xcap.conf
(You can try without those 2 files if you can't get them).
2. TO DO:
!!! AT SOME POINT OF CHANGING STUFF LISTED BELOW YOU WILL GET ALOT OF FC OF VARIOUS APPS. DON'T PANIC, JIST REBOOT YOUR DEVICE AND CARRY ON WITH CHANGES !!!
- in /OP directory delete folder _COMMON if you have one
- in /OP directory create a new directory called SUPERSET and set perms to 755
- copy all content from your carrier specific folder in /OP to SUPERSET. You can also just try renaming cour carrier's folder to SUPERSET instead of creating new filder and copying stuff to it.
- edit cust_group_mapping.cfg in /OP and change whatever you have after = to GLOBAL-COM
- open cust_path_mapping.cfg in /OP and make sure you have 999999,99=/OP/SUPERSET there on the list of providers
-edit official_op_resize.cfg and add SUPERSET_SIZE=[copy size value of your carrier's folder which should also be listed in the file]
-in /OP/SUPERSET (with your carrier's files coppied) edit cust.prop and in second line in the file change whatever you have after = to SUPERSET
- edit your rom current build.prop file and copy all additional stuff (in my case it was all the Fulmics ROM part of build.prop so from #Software Version down) to the build.prop acquired from your carrier's VoLTE/VoWiFi enabled rom. Add the coppied stuff at the bottom of the list.
- add following lines at the end of stuff coppied to your carrier's build.prop from step above:
persist.sys.cust.lte_config=true
persist.lg.data.iwlan.enable=true
# Debug Options
persist.dbg.ims_volte_enable=1
persist.dbg.volte_avail_ovr=1
persist.dbg.vt_avail_ovr=1
persist.dbg.wfc_avail_ovr=1
# Radio Options
persist.radio.rat_on=combine
persist.radio.data_ltd_sys_ind=1
persist.radio.data_con_rprt=1
persist.radio.calls.on.ims=1
# applying GPRI auto-commit
ro.lge.radio_gpri=1
ro.lge.amrwb_gpri=1
wlan.lge.softap5g=false
# 2015-10-12 [email protected] LGP_DATA_IWLAN [START]
persist.lg.data.iwlan=1
persist.lg.data.iwlan.ipsec.ap=1
# 2015-10-12 [email protected] LGP_DATA_IWLAN [END]
Save the build.prop file and place it over your current system default build.prop. set perms to 644
- open your device's hidden menu, go to
Field Test->GPRI VoLTE/VoWiFi->UX and tick 3rd, 4th, 5th, 6th and 9th for WoWiFi only, all except 8th for VoLTE/VoWiFi and 1st and 2nd for VoLTE only.
- go to your apns in network settings and make sure you have all the apns needed (in my case the are: internet, mms, ims and xcap). If you don't have them, try sending settings request message to your carrier's apn service center, if that doesn't help, add the apns manually (you must find your carrier's specific manual settings on the internet). You can also edit /system/etc/apns-conf.xml file and add missing apns manually to the list in above file. To do that you must find your carrier's apns on the list first, (list order by MCC-MNC code) under your carrier's last apn enter your VoLTE/VoWiFi apns in the same way the other apns in the file are typed.
-save apns-conf.xml, go back to apn list in network settings, tap overview->restore defaults and the missing apns you added to your xml file should appear on the list in network settings.
-make sure you have all permissions right of the created/coppied/edited files and reboot your device.
When your phone boots back up to Fulmics you should have your carrier's boot animation instead of default LG one, then you should see initial boot screen with "android is setting up" for a couple of seconds, then your homescreen. When configuring of your sustem is done, open quick settings and your VoLTE and WiFi Calling tiles should appear there. Turn on what you want and test if it's working. Remember, with VoWiFi you must have both WiFi and WiFi calling ON. The easiest way to tell if WiFi Calling is active is the presence of a headphone with little WiFi icon on the status bar and other places in your dialer etc. To test, turn on airplane mode, wait till WiFi gets turned off, turn it back on in airplane mode, wait for WiFi calling icon on status bar and try to make a call with airplane mode on .
REMEMBER! This guide will will only work if your carrier verifies WiFi enabled devices by 3 conditions: 1. Device supported, 2. Apns present, 3. ROM build match (info from build.prop).
I might have forgotten about something (or not ) but will edit if or when questions start to be asked

@mrbeem tried flashing back the kdz trough lgup but in OP i found only three folders: _COMMON, lost+found and OPEN_EU, plus a lot of individual files.
Any clues? Can you specify what files the operator folder should contain? Thanks in advance!

What rom did you flash in LG UP? Was it your provider's stock ROM with WiFi Calling service enabled or was it Open EU rom? OP should contain your carrier's config files of you flash your provider's ROM. The files should be in a separate folder with your Carrier's name (for example, Vodafone Italy should have a folder in /OP named VDF_IT etc.). Carrier specific folder should contain subfolders called: config, overlay, apps, media, poweron, poweroff. Most impostant are: config and overlay. Also in /OP there should be 3 files apart from the subfolders: cust.prop, official_op_resize.cfg and except_buyercode.cfg
Pics of content of cust.prop and official_op_resize.cfg from my carrier's folder (P4P_PL)

The OPEN EU that Bridge downloads when my phone is connected, and is the same one which is referred as "Vodafone Italy" on LG Firmware.
In /OP i have these files: op_list, official_op_resize, custom_path_mapping, custo_group_mapping, client_id, buerycode, strangely are almost the same found on fulmics.
In Open_EU i've overlay and config folders, and these files: official_op_resize.cfg, except_buyercode.cfg and cust.prop.
The strange thing is that the vodafone brand remains also with the fulmics, in fact at everye clean installation i found vodafone apps and vodafone configuration before restore my lgbackup, what a mess lol

Ok so you have the everything. Just delete _COMMON filder, create SUPERSET and copy all from OPEN_EU to SUPERSET. Basicly follow the steps. Build.prop is most important part. Plus check if you have all apns needed for WiFi Calling, if not, add manually as described. It is a mess, but the key is to put that mess in an order that enables WiFi Calling. Carrier's boot animation on fulmics is a very good indication that you're on the right path to make it work. Just a small tip... Maybe start from the UI part to enable the ability to turn VoWiFi on/off and then the rest. This way you'll be able to see if or when your service becomes active. So.....
1. Copy this to your carrier's build.prop after you've coppied the Fulmics part:
persist.sys.cust.lte_config=true
persist.lg.data.iwlan.enable=true
# Debug Options
persist.dbg.ims_volte_enable=1
persist.dbg.volte_avail_ovr=1
persist.dbg.vt_avail_ovr=1
persist.dbg.wfc_avail_ovr=1
# Radio Options
persist.radio.rat_on=combine
persist.radio.data_ltd_sys_ind=1
persist.radio.data_con_rprt=1
persist.radio.calls.on.ims=1
# applying GPRI auto-commit
ro.lge.radio_gpri=1
ro.lge.amrwb_gpri=1

persist.lg.data.iwlan=1
persist.lg.data.iwlan.ipsec.ap=1
# 2015-10-12 [email protected] LGP_DATA_IWLAN [END]
2. Replace stock fulmics build.prop with the one from your carrier's rom with Fulmics part and above lines added. Check permissions and reboot.
3. Ho to hidden menu Field Test->GPRI VoLTE/VoWiFi->UX and tick all ON apart from 1, 2 and 7. Go back to main hidden menu screen and to to Service Menu->WoWiFi and change value to 1.
4 reboot and check if you have WiFi Calling QS Tile added and WiFi Calling settings enabled in call settings.

Which ROM do you have installed?
Im using latest fulmics. And also i'm trying to create manually ELE_EE configuration. I have all information that i need from operator but not sure is it possible. Anyway i got this phone from LG baltics to do it.
The calling feature is not present in the tablet.
There is a reason there is no phone app in the system, and the only way you can call is through VoLTE and you have to check with your carrier if thats available for you.
In MIUI thread people have VoLTE calling enabled in china using their carriers, so you have to check if your carrier supports it,
If your carrier has VoLTE support but you still cant use it then:
1)Go to settings
2)go to storage
3)tap on total storage until you see a prompt
4)You can make a call by opening the configured VoLTE/video call/WLAN call option
5)Or you can use whatever app you use to make the VoLTE call and try it
Dont forget to hit the like button
MIUI blocked non-China carrier.So this way i tried,just can't enable th e volte function
enable to volte,must downgrade firmware to 9.6.4/9.6.6 version,then enable the volte fuction at "Setting"
If you can't enable volte,try to type *#*#86583#*#* at dailer apk,then it could enable the volte function

I added line:

There's no element of such, "hw_networkmode_preference" .....
For all of you who want this I think there is another way Go to playstore and download emui tweaker app and install its addon if you dont have root in settings there is option to enable 4g only .
After enabling it reboot your device. you will be having 4g only option.

Mine worked in first try! Screenshot here:

No thing
Recently I had some bad experiences with bad reception.
At the place of my new girlfriend is very bad GSM and LTE reception. At her place of residence I could not be reached with my OP3T and I could not make outgoing calls. When I called her from home, our conversations were interrupted every few minutes.
Neither with T-Mobile (company card) nor with my Netzclub+ Sponsored card could I make any real phone calls. When I recently gave her a Oneplus 3 I decided to make both devices (+my OP3T) fit for VoWifi and VoLTE.
The goal was that it should work with Lineage 17 for microg.
I have seen here some instructions that helped. There was always just a little something missing to make it work.
Below are the steps necessary to get VoWIFI and VoLTE for T-Mobile up and running:
No root solution required, no bootloader unlock required.
Ony TWRP needs to be installed.
1. Install QPST, (have used 2.7.460)
2. Install Quallcomm Diag Driver, i used 1.1 (have used 10037.3)
3. Extract modem firmware via TWRP (system/etc/firmware, or use mine from download link)
4. Enable adb root in developer settings
5. Enable USB Debugging and connect to device via adb
adb devices (check if device is shown)
adb root
adb shell
setprop sys.usb.config diag,serial_smd,rmnet_ipa,adb
6. Open PDC from QPST with admin rights and choose phone
7. Rightclick on "Overseas..." and deactivate for Sub0 and Sub1
8. Remove the "Overseas..." completely (select it and click remove)
9. Rightclick on "H3G Denmark Commercial" and set config for Sub0 and Sub1
10. Rightclick on the profile again (currently pending state) and select activate a few times until Sub0 and Sub1 are active
11. Modify Build.prop (system/build.prop)
Extract with TWRP and modify locally and add this new block underneath
block #VENDOR_EDIT
[...]
#VOLTE
persist.dbg.ims_volte_enable=1
persist.dbg.volte_avail_ovr=1
persist.dbg.vt_avail_ovr=1
persist.dbg.wfc_avail_ovr=1
persist.radio.rat_on=combine
persist.radio.data_ltd_sys_ind=1
persist.radio.data_con_rprt=1
persist.radio.calls.on.ims=1
persist.sys.cust.lte_config=true
ro.radio_gpri=1
ro.amrwb_gpri=1
persist.data.iwlan=1
#end
[...]
Overwrite the original build.prop with your new one and chmod 0644 (both using
using TWRP File Manager) the file.
12. Put VoWIFI + VoLTE simcard into Slot 1 of sim tray.
13. In Lineage enable VoLTE and Wifi Calling (enable prefer wifi)
To check:
After step 13 wait 20 seconds until sip registration with provider completed, then dial USSD code *#*#4636#*#* to open Field test
Open "Phone information" and check ims registration state
Ims registration=registered means you had success
The provider profile change is done at the EFS partition and stay there until you restore this one via twrp.
If Wifi is off VoLTE is used automatically, sadly Lineage OS 17.1 does not have a VoLTE indicator. But you notice that LTE stays on during call and that there is no delay now.
Without VoLTE there was a 3 seconds delay to switch from LTE to 3G/2G to make the call.
If you call via VoWIFI a new Wifi Icon is displayed in Call window.
Sometimes VoLTE gets preferred over VoWifi, although in wifi call you have set wifi call is prio.
Not sure yet what triggers this.
If you use Volte OpenMarket Commercial profile VoLTE + IMS Video call works, but not VoWIFI. So for us Denmark profile is perfect.
VoLTE also works with Netzclub (O2) card in slot one, but not VoWIFI. Could work with switching to o2 IMS apn (not tested yet since i only plan to use it for telekom currently).
I read that only slot 1 supports VoLTE and VoWIFI (chipset related) which may not be true since during the process i had a condition with VoLTE working in both sim slots (+ ims registred for both). This happened when i loaded the "Idea..." profile for testing purposes. Somehow it triggered a connection crash and did not change the profile but enabled VoLTE for both cards (this time t-mobile volte working in slot 2, netzclub+ volte working in slot 1). But since VoWIFI did not work i loaded Denmark once again and now only slot 1 worked again.
Now it is even possible to activate airplane mode and to call with T-Mobile number via Wifi.
Really cool.

Edit 2020-Oct-03:
Temporary magisk installation no longer required with latest lineage os 17.1 / lineage os 17.1 microg.
Just enable adb root in developer option, and in adb shell type "adb root"
Also attached mbn files only work for 3t, will update download link soon to contain 3 files, too
Can confirm, works on NOS 11 without using *#*#4636#*#*#. No VoLTE logo on the Status Bar, but it has the HD Sign when calling on Google Phone. Thanks for the guide!

Nope, I'm from Sri Lanka and I use the only provider that gives VoLTE. I had to google which option works with my Carrier, which was "VoLTE_OpenMKT....". Basically works with any carrier that provides VoLTE, a google search is needed to find which description to enable and if you can't, you need to test which ones are required for VoLTE.
Just me dropping by saying this was super helpful!
Running an OP3 on LOS 18.1. Wanted to avoid going back to OOS 9.0.6.
Enabled VoLTE on jaMobil! (T-Mobile Germany Network). I used the "Volte_OpenMkt-Commercial-CMCC" profile.
My profiles were fairly empty - not a single European Country name in the profiles. But worked Thanks again.
EDIT: Since I used the OpenMkt Profile I got everything but VoWifi working. But I don't have any country-specific profiles. Can I load yours somehow?
Ive had this issue and ive found just changing the build.prop locally on the device - Using TWRP
# Debug Options
persist.dbg.ims_volte_enable=1

Does the trick
Hallo, I have a problem with the device profiles for the modem. In the firmware there are the mbn-files in /system/etc/firmware/mbn_ota in two directories: mcfg_sw and mcfg_sw_NoCDMA. In QPST I can see the profiles from mcfg_sw, but not the ones from mcfg_sw_NoCDMA which are needed to use the op3 with the german telekom. What am I doing wrong? Trying to install the files via QPST also doesn't work, by using the load button I can choose a file, but the profile does not appear in the profiles.
Would perhaps sombody here who could explain the complete mechanism depending the mbn files in the firmware directory and the profiles shown in QPST?
Thank you very much in advance!
PS: VoLTE worked for a couple of days with the profile CMCC_Volte_OpenMkt-Commercial, but unfortunately the german telekom changed something, so it doesn't work anymore.

Switched to a OP 9 Pro in the meantime. But as i have said. VoLTE worked vor me. VoWifi not.
Good news for anyone having the Wing fall Back to 3G when making a call. You can activate VoLTE using a mix of the two following guides:
Guide:-How To Activate VoLTE,ViLTE,VoWIFI&ViWIFI LG Devices-LG Velvet 5G
Hi Guys Am Baljeet From India There Is A Path To Force Enable VoLTE On The"LG Velvet 5G LM-G900" Specifically Your Version Which Is The "LM-G900". By Default This Feature Is Disabled On This Model. Follow These Steps Given Below: A). Go To The...
forum.xda-developers.com
and
Lg g8x,g8,v60 Volte enable for all carriers, unlisted countries also
I will try to keep this post as small as possible. This will enable Volte for Phone ranging from Lg g8x, g8 and V60 without root or modifying the system files. Many have posted ways to get it, Iam only trying to help out the small bits missing...
forum.xda-developers.com
To make it as short as possible:
1) Create an empty directory named "enable_ue" in the root of the phone's main storage, using you prefered file explorer (like for exemple Cx Explorer or ).
2) From the LG Phone dialpad and with your SIM card inserted, type #*462633*#100# (for european LG Wing - LM-F100EMW) to get into the Hidden Menu. From there enter Field Test, then Universal Enabler -> Create New Config. Click on the four last check boxes VoLTE, ViLTE, VoWIFI and ViWIFI to enable these options. You won't be able to enter this setting if you haven't created the empty directory under point 1).
Go back to Field Test and enter Modem Setting to enable 5G if you haven't already -> RAT Selection -> SIM 1 Mode - > select GSM/WCDMA/LTE/5G or whatever you need + 5G. Go back and do the same with SIM 2 after, if you use it. Network mode in the network settings will then not show "5G prefered", but a number, like "26" in my case.
3) Go back to Field Test menu and enter IMS Stting. If you have Slot - 0 : OPEN / EU and Slot - 1 : OPEN / EU (or something else on each side of the / ), then you did everything right to this point. Exit the Hidden Menu and get your SIM out of the phone.
4) Enter th Hidden Menu again without the SIM inserted. Go back to IMS Setting and click on Slot - 0.
Under Subscriber enable IMS,ISIM & USIM.
Under Xcap\Ut. -> General, enable UT & USSD Over IMS
Under ETC, enable Check IMS Registration, Use rule-ID from responsem& Query on bootup
Under GPRI VoLTE/VoWIFi, enable VoLTE, ViLTE, VoWIFI & VIWIFI
Under Test, Preference Operator can be set as OPEN (what I did), or your carrier short name, or your County. Apparently does not make difference for some operator but some do require it to same name as theirs.
Preference Country this is important as this decides if VoLTE gets enabled, Find your country short code example USA is US , India is IN. Europe is EU. Find and try different short codes, I put EU.
Enable Support Volte AT command, VoNR, UAC Enabled & VoLTE Setting Enabled
You can now exit the Hidden Menu & insert your SIM back in. If everything went well, you should see the VoLTE icon showing up on the left of the network in the task bar, on the (my) Wing it's a small lifted phone headset with wave coming out of it. If you don't have it, check under the phone network settings - Mobile networks, if you got the VoLTE option and if it's activated. You might have to repeat some of the steps above with the SIM card inserted (as I had to) to make it work. Don't forget to check the settings for both SIMs if you use two. Not sure if all setting are kept if you reboot or reset the phone. You might have to repeat the preocess or part of it on each reboot, as for enabeling the 5G option.
Was tested on Android 12, as my phone didn't get Android 13 yet. But it's also working on my Velvet 5G that is on A13.
Many thanks to Baljeet Khairwal and johndaniel for their guides + all other persons who helped in the two threads.
