I switched from V10 (H860N) to G5(F700L) recently, and realized the voLTE is no longer available, and/or need some extra effort to get it available. the matter without voLTE is data qualify will drop during and few seconds after the call is end.
The carrier I am subscribing provides 450M LTE-A, I reckon I could leverage their voLTE to archive HD call but no longer on my F700L. Please advise if you have any hints on override the setting on this Korean phone

Hi Guys,
1. I am NOT an expert as to how VoLTE works in the back end.
VoLTE is the use of LTE to carry voice calls, as opposed to falling back onto 3G / 2G to carry the voice call. Advantages include, lower connection time, wideband audio, etc.
I've recently spent some time changing the CID and firmaware on my HTC 10 to one that is region specific to enable VoLTE on my handset.
It appears the way Apple implements carrier settings means that different carrier settings can be delivered to any iPhone, but it appears Android is currently managing this differently, as OEMs are creating variants of the software to cater for each region/carrier's variations.
What this means for me is, even if I purchase an unlocked device, if it isnt from my region, I will likely have to do extensive modification to enable VoLTE.
Does anyone know if Android N manages VoLTE differently? What's el-Goog thingking here?
Hello Forum,
I currently work for a Telecommunications Operator in Jersey, UK, We are soon deploying VoLTE across our network, however we are struggling with enabling VoLTE on the handsets, we have spoken directly with the OEM handset manufacturers but its proving difficult to get a VoLTE OTA settings from them any time soon,
I'm wondering if its possible to root a phone and get access to the VoLTE settings that we can manually enter in order to test and facilitate our VoLTE roll out, we have access to various handsets including Samsung S8/S9/9+, iPhone, Sony XZ. Please let me know if this would be possible
Thanks, Regards
Hello,
Is anyone able to give any info on this? Ideally we are looking at being able to manually enter VoLTE / IMS configurations, Is Rooting all that is required to enable this or is the a specific ROM I'll need to install also?
Thanks, Regards
I have tried this new feature coming with the stock Oreo ROM and received a message from my mobile carrier initially, welcoming me to WiFi calling. All network settings seemed to be working fine, I was also browsing internet with no problems, all apps were connecting and responding as expected. However the first time I tried dialing one of my contacts I've got a message "Server error. Try again later." on the dialing screen itself. It looked like the call couldn't be connected. This happened to all outgoing calls, I suppose to all incoming also although I couldn't confirm that.
I tried many things like restarting the phone, turning data on and off, going into flight mode and disabling it, in the end I reset all network settings disabling LTE advanced services before doing that and enabling them again after the reset, but I still get that error. If I disable LTE advanced, all calls get connected with no problems.
Does anyone know if this is something with a list of supported devices explicitly enabled by the mobile carrier in their network? I am considering calling my carrier for more information but the fact itself I have got a welcome message means the device has been detected as part of the advanced services network. Perhaps there are some network settings I need to enter? Anyone ever used Axon 7's WiFi calling/advanced LTE features on any network?
Does that maybe include VoLTE which the carrier may not support?

Well according to the link provided and what I know, LTE is supported by my operator, but I wonder if it needs to be specifically tailored to a phone model by them and/or the 8.0 update by itself is not providing such functionality or it is limited by default. And I think it may be the first since ZTE products are never on the list of supported phones by any operator. But I couldn't claim it for sure as otherwise ZTE would not have included it at all with the 8.0 ROM and there are so many basic or very old models like LG K8 or Microsoft Lumia 550 that are supported.
Has anyone tried using "LTE advanced" on their 8.0 yet?

LTE Advanced = Volte
If your carrier does not support Volte, keep this option off.
WiFi Calling is something separate and not related.
If your carrier does not support WiFi calling, keep this option off.
You should still get LTE service with both of these options off. I personal find WiFi calling to work poorly, so I leave it off even though my carrier supports it. (TMobile US)
Also, there is a Q and A section for these types of posts. Don't post questions in the Guides and News section please.
Thanks for the input. Both of these options are reported to be supported by my carrier on their website. Also I always had LTE before 8.0 so simply wanted to try the new "HD voice and advanced communication service" as described in the latest firmware.
About posting this thread in the news & discussion section, this only relates to Oreo which was only recently released to the public so it is a completely new feature for the Axon. Most of the other threads are too general and since there will still be many people with 6.1 and 7.0/7.1, I would have hardly got any response whatsoever in there. For now I will keep this new option off and will contact my carrier for the support of the Axon and ZTE in general.
Hello,
I have read and found success making options for wifi calling appear in the stock menu when it was absent before, however the phone is nonetheless unable to make wifi calls after enabling. Tried placing phone in airplane and turning wifi on.... or just choosing the "wifi only" option for making calls in the network menu - Resulting message always states to connect to a wireless network to proceed with the call, even though I have an excellent connection and internet works fine.
I have done an exhaustive search for methods to successfully use T-Mobile's wifi calling feature on my phone.
My initial research revealed that the option should work so long as your phone supports wifi calling as well as your carrier.
The wifi calling option was absent (as well as VoLTE) on the stock ROM, so I had high hopes that a custom ROM which included the feature would allow me to utilize the service with T-Mobile (my current GSM carrier).
After a slew of unsuccessful attempts to make calls using wifi vs the mobile network, I finally called T-Mobile's tech support who was actually quite helpful, but essentially stated that wifi calling through T-Mobile requires the carriers own proprietary software to work... in other words, even though T-Mobile likes to promote the ease with which you can BYOD (bring your own device), it would appear that the wifi calling feature is only possible when buying a phone directly from T-Mobile unless a custom rom is built which is at least partially based upon T-Mobile's own proprietary software with regard to wifi calling.
If ANYONE has had any luck at all placing wifi calls on the T-Mobile network domestically in the U.S. using the global/MEG7 version of Redmi 5 Plus, your assistance would be immensely appreciated. I have found that, although my phone does not support multiple LTE bands used by T-Mobile, I am still able to make LTE calls quite frequently in my region using the single supported band.... however, my home is a "dead zone" so to speak and, even though I am smack dab in the middle of an excellent coverage zone, my service inside the house is poor enough that others' attempts to call are unsuccessful, leaving me unaware of the call unless a message is left.
At this point, I am getting ready to throw in the towel so any advice or success stories would be greatly appreciated - or, on the flipside, a validation that wifi calling is just not possible at this time so I don't have to drive myself crazy with a continued search for which a solution does not yet (or may never) exist.
Many thanks for your help!
My carrier is very particular about which phones they open up the Wi-Fi Calling feature to. Generally, they'll only activate and support the feature on phones that they have directly sold & are running carrier-branded firmware (ugh).
I've managed, however, to get Wi-Fi Calling working on my carrier via my Z5c, which is definitely not a supported model. (Long story.) And it all works great...except that I cannot for the life of me get MMS to function over Wi-Fi. I know what the basic underlying issue is that is preventing this from working (APN type 'mms' is not able to be used as a bearer on the IWLAN RAT), but have not yet found a way to work around it.
This leads me to ask: is there anybody out there (still) using a Z5-family phone that has working Wi-Fi Calling actively supported by your carrier? And if so, can you send and receive MMS when you are only on Wi-Fi (Airplane mode on with Wi-Fi re-enabled) without problems?
I mean, if this isn't a supported configuration/feature on the Z5, period, then I'd like to know that before I waste further weeks banging my head against a wall that's never going to budge... It seems unfathomable to me that any phone with Wi-Fi Calling *wouldn't* support MMS over Wi-Fi, but this is a rather early VoWiFi implementation, so who knows.
