[MODULE v17.x] VoLTE & VoWiFi Enabler (2018-09-20)

[ToucanSam]

Update: This module was a trial. The results seem to indicate that there is significantly more work to do to enable VoWiFi or VoLTE.
I will leave this module up for anyone interested in enabling the options, but please be aware it will not make these features work.

VoEnabler
This module edits build.prop to enable VoLTE & VoWiFi features on your device.
Download via Magisk Manager or from GitHub.

Important:
This module will not add VoLTE/VoWiFi support to a device that doesn't already support it.
The module will not add VoLTE/VoWiFi support to a carrier that doesn't already support it.

Notes: 2017/08/01
I've changed the module from VoLTE Enabler to VoEnabler and added VoWiFi options. I was going to split them into different modules, but I don't think there's really a point. If you want one you probably want the other and if your device doesn't know what the options are then it should ignore them anyway.
Suggestions: I'd remove the "VoLTE Enabler" module before installing this because the options are the same, but even if you didn't, it won't cause problems.

What did I change?

# 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

Why?
My carrier supports VoLTE/VoWiFi but not on my device. I made this module to forcefully enable it to test if it worked (it hasn't so far).

The only reason I've published this is to give others the chance to try. It may very well do nothing at all. If no one reports success, then I'll update the topic and ask the mods to lock it.
As I understand it, VoLTE and VoWiFi both require carrier side support anyway. Next step would be to see if it's possible to get the settings from compatible devices and see if it's still possible to make a module.
If anyone has any to add or suggestions for doing this, please let me know.

I'm not going to be providing any support for this because I'm not convinced it even works, but your mileage may vary. *shrug*

2018-09-19 (v1.3): Update template for Magisk v17.x and removed post attachments. Please check Magisk Manager or GitHub for downloads.
2017-08-16: Updated post to reflect that this module will enable the options, but won't make them work. Leaving module up for anyone who wishes to experiment.
2017-08-02 (v1.1): Removed "persist.data.iwlan.enable=true" as this was reported to break WiFi calling on some carriers.
2017-08-01 (v1): Renamed to VoEnabler and added VoWiFi options. Replaced attachment.
2017-07-31 (Beta): Initial commit.

Make a call to someone，When you are on call，open browser，fresh a webpage，if it freshed，it's OK

It is not like that. It supposed to be your are on LTE, and then when you trying to make a phone call, it will immediately switch to HSPDA/3G, and get back to LTE as soon as the call ends. That is the symptom that VoLTE is not supported by the carrier. So if it is working, it should remain on LTE whenever you making a phone call.

What advantage does the flame make and is it maintained in LTE?

How to know it work or not

If it's working, you'll see a little VoLTE icon in the status bar like either of these...

Edit: Sorry. Just to clarify, if the module is working you'll see something like this... in "SIM & Network" in settings.

The advantage is higher quality voice when on phone calls. That's really about it.
VoWiFi also exists which lets you make and receive calls from WiFi in case you don't have signal.

Not only higher voice quality but faster dialing too. [emoji6]

Thanks

On my phone i changed the CSC-File to enable VoLTE and VoWiFi, i didn't know that it can be enabled in the build.prop too. i have a S7 Edge BTW.

From memory, that's a Samsung only feature? CSC files.
The build.prop stuff is generic so should work on any device. And Magisk so means not modifying /system.

I'm still not convinced it does anything by itself, but I figure it's easier to make a simple module and let folks give it a try. If it genuinely does nothing and no one can figure anything else out, then I'll delete the attachment and modify the first post so at least there is something to search for that says "THIS DOESN'T WORK. DON'T BOTHER".

Just tried this on my OP3, gave me the enhanced 4g option but when I turn it on it doesnt make any difference. On call the network drops down to 3g/H from 4g LTE

Yes in the CSC-File you can enable and disable, some hidden features specifically for Samsung Phones. I also made an Magisk Module to activate some features systemlessly like App-Lock, Floating Messages, VoLTE, VoWiFi and other but I will test out your Module and look if it works with my phone.

Just tried this on my OnePlus 3 that is on ATT and it did not work. I did enable it in settings as well before trying. If we could get this to work that would be great!

I have a Huawei P9 lite and I installed this module. New options have appeared in the settings but unfortunately despite my provider supporting VoLTE when I call it always goes to 3G

doesnt work with BQ Aquaris X5 Plus (Gohan)

 

[ToucanSam]

With the 1.1 update I'm getting VoWiFi and it seems to work. VoLTE remains elusive.

 

[GuestK00351]

I don't think it's that easy.
I asked the developer of the ROM I'm currently using for activating VoLTE.
He said maybe in the future, because a lot of modifications have to be made, not just editing build.prop.

Magyar Telekom also introduced the VOLTE service. I asked why it did not work on my OP3 phone. I got the answer that it would only work on Samsung phones on their network.
No comment...

How to edit the VoWiFi settings to put my carriers server to connect ? I'm on Orange ro and we have VoLTE and VoWiFi.
