WIFI calling implementation ?

Any one know how Tmobile plans on implementing wifi calling for the nexus 6 been an stock android rom? you guys think all AOSP roms would be able to get wifi calling once this patch goes live?

Honestly, I expect Google to implement it just like Apple does. Develop the feature directly into the device and firmware and then allow minor updates to work with other carriers such as US Cellular and Sprint. If they don't bake it into "AOSP" then I doubt third party AOSP built devices would support it.

yes, i'm hoping its an android thing and not a T-Mobile thing.

Can We Get a Carrier Specific Rom List Please

Here is the reasoning behind my request.
I am on Tmob and have a N6. I was fine stock rooted on 5.0 then 5.0.1. Then I decided to try a few roms. One that said it was for ALL carriers, didn't allow me to get calls unless I was only in 3g.
T-mobile is the ONLY one using a 47m ROM. All others are at 47i, why is there a difference? The radios most likely. I am 95r and 98r doesn't work on TMobile very well.
Can we get a Thread for EACH Carrier? They aren't all the same, at least from my experience. Sprint, VZW are different and have problems. I hear VZW users need to use 98r for "best results"
Go ahead, blast away. Just waiting for the "senior ops" to go to town on this one!

I'm on vzw and every ROM I've tried is fine. Have you updated to the latest image from google. Or are you still on 5.0.1

With many phones, Samsung in particular - there are massive hardware differences that require several separate forums to manage.
With the nexus 6, the hardware is identical on all of them.
There are 2 specific builds that are slightly different and as you mentioned, they are M and I.
What we think is (but unproven) that M is for T-Mobile USA and I is for Australia. We have no concrete proof of that. Nor am I sure what the differences are. If you're using stock-based ROMs, try to stick to M builds.
As for AOSP, I'm not sure anyone knows what the difference is for T-mo. Maybe one day we'll find out.

Thank You for the Reply.. I would agree with the thinking about M. Like I stated a non-M build killed the incoming calls unless my phone was on 3g with Enhanced 4g unchecked.
I was just asking for a Carrier Specific Rom thread thats all.

Im on a 5.1 with 95r and 47M is my Build (nocturnal rom) its a Tmobile N6.. All other roms killed incoming calls unless I was stock rooted. CleanRom 2.0 and 2.1 with either 98r or 95r had same results. I like @scrosler roms, but can't live without getting business calls.

Yeah. I think its a good idea to have a thread that lists all t-mo compatible ROMs, but first we need to learn what the actual difference is. Perhaps its just a RIL or something. In which case, there may just be a flashable zip required.
I just think we need to know more at this stage.
@efrant, do you know the differences? @simms22?

the aosp roms were missing code that made the tmobile devices not receive calls on lte, that has been fixed and should be in all roms that have been recently updated. i use terminus, which includes the code, so tmobile users get calls on lte, and volte is working. besides that issue that has been fixed, all carriers will work on any aosp rom. theres no such thing as a carrier specific nexus rom.

Was the code added to aosp by Google? Or is it a community commit?

AOSP contains only Android OS nothing proprietary (proprietaries are included as a standalone) but when Google provided the binaries--proprietary libraries, applications were missing which caused VoLTE not to work properly. Myself and Sykopompos worked on the blobs and having VoLTE working, they were pulled from the factory image / deodexed OTA.

[Q] VoLTE

Answers to this question are either totally unanswered or vague.
Can/will the M7 support VoLTE (Voice over LTE) or not? Three in the UK is upgrading it's network to support VoLTE in the 800mhz frequency range. It would be nice to have it if at all possible. Sadly there is very little info on whether the hardware supports it and if the software (Lolipop and mods) will support it or not on the M7.
Can we have a thread with solid answers as this is quite important for some of us who have reception issues.

I've been searching and curious (without avail) about the same question. I'm currently using Viper/Venom ROM v9.0.0 that uses a base from the M9. The M9 supports VoLTE and thus the option appears in the menu on the M7. However it does not function and if you try to interact with it the phone service crashes. This makes sense since it was developed for M9 hardware. Does this mean it's totally not supported on the M7 from a hardware standpoint - nope. But without the proper software it's not going to happen. Is T-mobile (or whoever your carrier is) going to develop the feature? Probably not. Will google? Maybe, seems to be appearing on google phones as a standardized feature. Same for wifi calling...

With the AICP MM ROM for the m7, I called my mom and it said "VoLTE" in blue letters. I never really took notice of it until after I went back to Sense... I'm going to flash that ROM again and give you an update soon (if not I probably forgot, sorry). And btw I know this thread is very old but I just wanted to chime in and say what I've found

So, that was an interesting and timely reply. I recently upgraded my M9 (s-on) to a firmware that is too new for MM CM so I went back to my M7 for a while. It's still on a sense based rom but I may give AICP MM a spin on my M7- thanks!
:edit
Now that I think about it, the only reason I upgraded to the M9 was for VoLTE, the M7 is the perfect size phone, god how ridiculous new phones are these days, every iteration just a liiiiitttle bit bigger. enough already lol /rant...

I flashed AICP last night and called my mom again, but unfortunately no VoLTE... It's odd because I clearly remember seeing those blue letters when I was about to hang up :/ If I find anything new I'll post it here!

Maybe, you didn't remember well, what you've seen? Because I think, it's impossible.
So this thread is a year old (time to re-activate it?), and I wonder about the same issue. I tried on the M7 with different firmwares (european latest hboot 1.61, GPE hboot 1.54), using LineageOS 14.1 (Android N 7.1.2), but with no constellation it's possible to activate VoLTE.
I figured out, that it depends on "the hardware", but IMHO that's not really the reason because the LTE radio chip performs LTE correctly. So I expect it depends in reality on the "radio firmware" to active VoLTE.
And I have never seen a radio firmware for the M7, which is able to perform VoLTE.
If somebody knows about a "patched" or "modified" radio firmware for the M7, to activate VoLTE, please let me know!!! (Because LOS 14.1 runs well, and is -- from the OS side -- able to perform VoLTE).
Thanks a lot,
samhhmobil

Thats not true, Lineage in general doesnt support VoLTE. You can read about exacly this on AICP G+ page because a lot of people asked for VoLTE Support. Official answer was "as long as lineage doesnt implement it we dont have it" There are some unofficial Roms for other devices where the maintainer did implement VoLTE. The big problem with VoLTE is, in nearly every country and provider it has a different standard so its not just add something and it works for everyone.
But Guys, do you realy need LTE while your in a Call and 3G isnt enough? I think 42mb/s should be enough for everything and thats what you actually get while in a call. Btw our m7 only has an internal read and write speed at about 5-15mb/s so its useless :silly:

New to Nexus 6

Hi, I just got a Nexus 6. I want to move to an aosp based rom as soon as possible. I am on t-mobile and wifi calling is a must. My question is does P.A.C. rom support wifi calling and volte like cm 13 does?

If you can't find your answer in the Opening post features list, or by searching the thread on WiFi calling and volte, I suggest taking a nandroid backup and flashing it to find out. :good:

I am not using wifi calling because it is not available here in the Netherlands. .
T-MOBILE want's to earn money with the services they offer. It seems logical to me that this wifi service only works with T-Mobile branded devices.
When you flash an other rom you need to read about the new rom. In the description there must be stated that wifi calling is supported.

You are correct for all devices but the nexus 6. the stock international nexus 6 rom works with their wifi calling and cm 13 does too.

They actually released Lollipop builds but have been largely inactive since then. There are some releases (I believe unofficially) that are floating around on androidfilehost and some other places... But they are in their infancy of Marshmallow. It's based on CM13 with (last time I checked a few weeks ago) not too many features added on top and probably largely considered to be experimental or in the alpha stage of development.
For sure Pure Nexus Project and Dirty Unicorns support wifi calling and I think Chroma and AOSiP do too. Any ROM based on AOSP should really support it but ROMs based on CM13 may or may not. I've seen conflicting information. From a reddit thread, a user said WiFi calling works on CM13 for the Nexus 5X but not his Nexus 5. Nexus 6 I am unsure, but make a nandroid backup of your current setup and go wild on testing different ROMs :good: I can't tell you because I don't have Tmobile anymore (although I did for a short period with my N6)

Ah, you mean the pacman rom...I used it alot on lollipop, but yeah, not to be seen anywhere since most of us switched to MM..
BTW, almost all the current roms in the N6 dev section have wifi calling now, both the AOSP based ones, and the CM13 based ones...

Oh, thanks for the info. I wasn't aware CM13 had native wifi calling support. I'm glad it's baked into Google AOSP now for Nexus devices. I remember using a Galaxy Note 3 and so bad I wanted to put an AOSP/CM based ROM on it when I had Tmobile but the support for Wifi calling was only available on stock bloatwiz/lagwiz/whatever you want to call the garbage stock firmware. And where I live had zero Tmobile signal. Had to get by with root and wanam xposed. But now I'm back to the glorious nexus master race (and another carrier, so I don't need wifi calling).

Thanks. My last device did not support PAC rom. I was not aware that they are not really active any longer and there is no marshmellow version.
Thanks for all the info.

What is P.A.C rom?
I got the impression that it is a custom ROM and not the international stock rom.

Its this rom..

I dont think there is one for Shamu.

custom roms???

this device has amazing specs but lack of software support. it would be amazing some custom pie or 10 roms
i don't need asus own features
i really like a pixel experience,los or omnirom the most stock android feeling rom( +120hz you will get a more buttery smooth experience)
please somebody create one
sources are available
even zenfone 6 has custom roms

Yes please !

It will be nice if this phone receives TWRP and custom roms.

Didn't it JUST launch globally today?
Let's give it some time.

i really hope somebody create a stable tpwr since sources are available and the most stable rom out there like omnirom or pixel experience
preferred omnirom

IMO I don't believe it will receive support anytime soon. Unless ROG was able to convince your standard Android enthusiast that this isn't just a gaming device. People that purchase this phone are mainly interested in one thing, gaming, not development. So, ROG has to convince those types that this device is just as good as those others.

It will be interesting to have custom roms for rog. waiting also

My thoughts exactly. Custom roms are awesome but they are generally made or ported to be used by a majority of the phones out there. If we got a custom rom ie. AOSP, who would code in the air triggers from scratch?
Having said that, the stock rom is quite good. I don't have the need to root it like I did with my Mate 20X to shrink down the gigantic icons/screen because by default Asus allows a lot of customization.

Apparently the American version doesn't have volte or voWi-Fi as well.. that, along with the fact that it doesn't support band 71, are big reasons why your normal or typical Android enthusiast/ developer is not going to purchase this device

So does this apply to the Tengent games (CN) version too? I am getting the cheaper CN version and then going to flash the WW (Global) Rom, so essentially I guess I am asking is this a hardware omission, or is it ROM (software) based?
And how does this typically affect say a normal phone user?

It might get an update. As for band 71, I personally don't care because I won't use it all.

As I understand it, it doesn't have to do with software or hardware, they just simply don't support volte of vowifi. In China, they do. So, it's not the device, but the companies choice. May be some restrictions that we aren't aware of, otherwise it doesn't seem like a very smart decision. I was all in until I heard this. 3G is going to be removed from our networks in the next few years, so voLTE is kind of mandatory. Even now, if I don't have voLTE, I can't make or receive calls. VoWiFi, that's beneficial if you're cell signal is low for whatever reason. Maybe you work below ground or in Faraday cage style buildings. Plenty of uses for it. As far as band 71, no, I probably don't need it. But that doesn't mean I wouldn't want it just in case. Always better to have and not need, than to need and not have.

This is wrong for TMO. It's in the SW. There's an option for volte carrier check on xiaomis phones. A simple dialer code disables this check, and volte works on TMO. I'm hoping there's a way we can do this on the rog 2. That, or a build.prop edit to enable it. There has to be a setting hidden that disables volte in us.

I've just been reading a little bit more up on it, and apparently, ASUS didn't pay the cell carriers in North America for provisioning costs. That's why it won't work. So, regardless of software, hardware or any other type of hackery, it won't work in North America.

So is this just a bad/dumb move by Asus or what? I mean I honestly don't know if these omissions will affect me, all I know is I still own a Samsung until I get the Asus and was always able to use my Samsung phone how I wanted to use it
