VoLTE on P8 and MM - Huawei P8 Questions & Answers

Hi guys,
I've a huawei p8 with android 6 (rom gratitude v5) and i can't find the option to enable VoLTE (voice over lte /4g).
In fact, when i'm calling someone, it automatically switches from 4G to 2G and i can't use it because it's too slow.
How can i enable it?
Thanks and sorry for my english.:fingers-crossed:

up.

You can't enable it. It needs to be implemented in the software from the manufacturer(Huawei).

I thought it was already implemented..
Thank you!

I need volte uptodate

Volte is included in Arrow Rom Version 2

Is there any rom which supports volte and has audio fx (v4a preinstalled)???

Well we all know that we have lost hopes about Android N so i thot why not to try some good roms but i dont know which rom shud i use as an daily drive so here i create a thread to ask the following question given in the title?? It'll be my pleasure if u help me!!
Ps i know everything about bootloader and rooting stuffs....
Thankyou
Compared to some other Moto devices, ROMs are slim pickings for this device by comparison... there is only one ROM with v4a baked in that I know about is OrionOS. As far as VoLTE is spotty on most custom ROMs, works on some carrier/rom combinations and not others.

Is you VoLTE carrier Jio? If so, this device does not not support Jio's VoLTE service... And the few carriers it does work on, Verizon and T-mobile, are hit and miss quality wise.

yeah ur right
its jio.... :crying:
This phone doesnt support VolTE, check the compatibility list given by Jio first, it only supports 4G data!
Use shortcut master
Can someone try using shortcut master and see if volte can be enabled.

I just flashed cm14.1 (20161119) build , it is very smooth and good for daily drive but voLTE is not supporting , can anyone please confirm?:fingers-crossed:
There's still no updated modem firmware from Oneplus (which in 99/100 cases comes with a newer ROM for the phone) adding voLTE, no.

No I mean , Still we can use data in oneplus 2 from voLTE right? cant able to select that also...
I am from India, I was using Jio for data alone . It was working fine in OOS.
Cyanogenmod supports voLTE, however the closed sourced binaries from Oneplus does not support telephony though the 4G modem. So there's not much we can do other than use SIP telephone to call using 4G data if you absolutely must use this because of lack of GSM/2G.
So many threads about volte... Just use 2g instead

Reliance Jio functions exclusively on the LTE network, so 2g fallback is not an option. That's the reason for all the VoLTE requests.

There aren't really that many providers who offer free voice calls and data at the price point of absolutely free. Come to think of it, I can't name a single one in my region.

It seems like more then just coincidence that Jio operates in the same region as Oneplus main target audience lives, and then has this offer you can't refuse and by accident the newer flagships supports this provider of free telephony, it makes me wonder how much Oneplus is sponsoring Jio.... ??
use jio's own app jio4gvoice to call

I wanted to report my latest finding on VoLTE, so many questions can be resolved.
For the record, I am based in New York and on T-Mobile, so my VoLTE settings are not the same as many of you on Jio in India, so it works for you, it may not work for others.
Now as to my findings:
OOS 3.5.6 - VoLTE works out of the box, no issues!
CM14.1 based ROMS (RR/AICP and variants including Lineage OS) VoLTE does not work!! That includes Official and Unofficial builds.
CAF based ROM (halogenOS) VoLTE works out of the box, no issues!!
AOSP based ROM (CosmicOS) VoLTE works out of the box, no issues!!
Now, I am not sure what the issues is with CM/Lineage OS ROMs that prevents VoLTE to function - but this might give insight to developers.
Is there anyone else I here from USA and on T-MOBILE that can confirm my findings or provide other info?
Thanks

Lineage OS: VoLTE support in Denmark

Hello.
I have a Pixel 4 (Flame), which is running a Lineage OS derriative called Calyx OS (This was an issue when it was on Lineage OS as well). I struggle with the fact that VoLTE does not seem supported by my carrier (Telmore (A sub-company of TDC, so their APN's work)).
Has anyone had VoLTE working with LineageOS in Denmark? If so what device were you using?
Thank you in advance.
P.S. this is normally something I would not really care about, but the radios on the installation that my employer has got installed (By TDC), recently shut off 3G to make room for 5G (So now I can't receive or make phonecalls).
