yes I do, and may start using that. However, the downside is no cal & contract OTA syncing.

whats weird is the fact tmob are messing around with http & https ports but not imap! when email & Opera fail, IMAP still works. I can also still sucessully ping a server from the device (bbc as an example).

I cant understand why other tmob users dont have this problem. Unless most people use 3G and don't realise its not working correctly.

Right im on T-Mobile UK and use Push so ill help out any way i can.

How do i find out the heart beat interval?
[Tilt, TyTN II, MDA Vario III General] flashflash:
Thanks, I really appreciate your help.

Firstly you need to activate the activesync log.

Select activesync , menu >Configure Server >Next >Advanced> Event Logging change to Verbose> Next> Finish

Wait a few hours for the log to record some events then view them by using a file explorer. Windows/Activesync/CtrLog.txt

Look through the log for Heartbeat=480 (this is the heartbeat in seconds), also in the log do you see any ping failed?

many thanks for your help.

FYI 480 is the minimum heartbeat and I still get a failure with that! So the phone does a full sync every 480 seconds. On a Vodafone sim, the heartbeat got to 1900 seconds with out failing.

one final question, are you using 3G or force 2G only. Cheers
[Tilt, TyTN II, MDA Vario III General] jaso2005:
Ok logging is enabled and im just waiting on Propagation on the DNS for everything to start working as it should.

Im using 3G matey. As soon as everything is all fired up ill let you know my heartbeart.

[Tilt, TyTN II, MDA Vario III General] SASSBS:
Hi I am also on T-Mobile, I get the Direct Push working without a problem once we changed to Exchange 2007, under 2003, I had the same issue as you.

Now that I am on 2007 the heatbeat is 480 seconds, however the battery life is double what it was under 2003, and emails arrive immediately.

Only problem I have with T-Mobile is getting access to our internal network over the VPN, it connects but I cant access anything, like your problem T-Mobile are useless.
[Tilt, TyTN II, MDA Vario III General] flashflash:
mmmm, heartbeat still only 480 seconds. Something is not right here with T-mobile, reading more into the technical side of push email, 480 seconds is the minimum default value, we should be seeing more like 1500 second or more (conditions allowing).

With a Vodafone Sim the heartbeat I get is around 1400-1800 seconds and vastly improved battery life.

Hey guys,

yesterday I got my new Mi 8 <3 It's really nice...

I wanted to check if I can use wifi calling, but there is no option for it in settings. I can search for it but there is only text as you can see in the screenshot.

I checked the "hidden menu" under *#*#4636#*#* but the option is greyed out, too.

I'm living in Germany with Vodafone and wifi calling is included in my plan.

Any hints? Is wifi calling working for you?

Thanks :)

I think the Mi8 is not supported by Vodafone.
[Xiaomi Mi 8 Questions & Answers] baddevil2:
I don't get it :/ Other Xiaomi phones are working, too. I thought Xiaomi have to implement the profiles? I don't know why this is always so hard, Android does support VoWifi since some major versions natively :(

It was one point, why I bought the Mi8 instead of the OP6. I hope it will get it fast :D

Hi,

sorry didn't have time to root the device yet :(

I will inform you as soon as I have new information.

Maybe someone else can try it :)
[Xiaomi Mi 8 Questions & Answers] DiePlage:
No, "HD" usually means VoLTE which is a completely different thing. Could you please try to enable flight mode and after that ONLY enable WiFi? If you are still able to make / receive calls, than WiFi Calling is working.
[Xiaomi Mi 8 Questions & Answers] grootooter:
Tried build.prop change, Wifi-Calls enabled and preferred *#*#4636#*#* shows the switch enabled, but (three dots - IMS status) shows VoWifi "not available". VoLTE works same as before (without build.prop tweak). I checked both O2 and Vodafone Germany.

Seems there is no solution for VoWifi at the moment.
[Xiaomi Mi 8 Questions & Answers] baddevil2:
Come on, don't destroy my hopes :D :( Too bad...
[Xiaomi Mi 8 Questions & Answers] omek07:
My friend I don't think that the Wi-Fi calling works like that. The phone must recognize that you have sim card in your phone. I think that If you enable the aeroplane mode the phone doesn't recognize the SIM card. I am not 100% sure thought.
[Xiaomi Mi 8 Questions & Answers] baddevil2:
Yesterday I tried it with latest Xiaomi.eu rom and Magisk Module (to write build.prop entries).

[Xiaomi Mi 8 Questions & Answers] baddevil2:
Afaik it should work, even if my provider doesn't support the device. You can enable VoWifi on all OnePlus devices maybe you have to switch profiles with Qualcomm PDC but even with other profiles the Mi8 won't register with IMS. Yesterday I flashed LOS and Pixel3ROM but none of them registers with IMS
[Xiaomi Mi 8 Questions & Answers] -fluffy-:
yes i can activet vowifi on op6 but it dont work because my provider dont support the phone

an i can do the same on my mi8
[Xiaomi Mi 8 Questions & Answers] baddevil2:
There is a german forum with a guide (for one plus) on how to switch profiles (keyword: H3G_Denmark_Commercial for e.g. german Vodafone) and all of them say that it works and OP is not supported by providers. So there must be a way :D Even my provider tells me that if my phone support wifi-calling it should work with them.

Edit:

Edit:

Maybe some guys can help testing to find a custom rom where VoWifi/Wifi-Calling should work.

Xiaomi.eu: VoLTE is working but no VoWifi/Wifi-Calling for Vodafone Germany

LOS16: VoLTE is working but no VoWifi/Wifi-Calling for Vodafone Germany

Pixel3ROM: VoLTE is working but no VoWifi/Wifi-Calling for Vodafone Germany

Maybe someone can try:

AOSiP

Havoc

For german providers those profiles should work:

Vodafone: H3G_Denmark_Commercial

Telekom/o2: Commercial-DT-VOLTE

You can switch profiles with PDC (Qualcomm) and Qualcomm drivers.

Hello baddevil2,

did you get wifi calling to work on the Mi 8?

I've ordered a Mi 8 lite (global) and consider switching to VF-DE. As I have bad coverage at home I'm depending on wifi calling.

It would be great to get a short feedback. In case it's not working the list of potential providers is reduced further...

Thanks!

[Xiaomi Mi 8 Questions & Answers] baddevil2:
Hey mate,

yes got it to work ❤️ After switching to AOSiP, flashing VoEnabler in Magisk and one call to Vodafone to enable VoWifi by them it worked instantly ? Afaik MIUI has VoWifi support too(knows from some Poco users) but you have to select a working operator profile in Qualcomm PDC.

Edit:

Will update the first post when I have time with some information
[Xiaomi Mi 8 Questions & Answers] botsj:
Thanks for the fast response! Great to hear that it works, even if it's not running out of the box.
[Xiaomi Mi 8 Questions & Answers] praveenkv1988:
which AOSP rom did you switch to?
[Xiaomi Mi 8 Questions & Answers] baddevil2:
As I wrote => AOSiP
[Xiaomi Mi 8 Questions & Answers] praveenkv1988:
Tried the same. Did not work for me. It shows setting to enable wifi calling. But does not connect to VoWiFi(Does not show on status bar, Also, calls does not show as WiFi call.)
[Xiaomi Mi 8 Questions & Answers] baddevil2:
Last week I switched from AOSiP to Havoc. On Havoc VoWifi and VoLTE is working, too.

As I said before, it is possible that your default operator profile is not VoWifi capable. In this case the only way to get VoWifi hopefully working is to switch the profiles in Qualcomm PDC. But I can't promise that there is a working profile in efs partition. And you must be 100% sure that your operator activated VoWifi for your plan.

AOSiP and Havoc doesn't have VoWifi icons so you won't get any in status bar. The only way to check if you are registered with the correct IMS service is to look it up on *#*#4636#*#* or to try a call.

And I don't know if the magisk module 'VoEnabler' does work, I am using the module from [MENTION=3068641]jamal2367[/MENTION] from here -> https://jamal2367.org/downloads/Mag...T_OOS-OB_VoLTE-VoWiFi_Enabler_v2.0-signed.zip

Thanks to him by the way ??

[Xiaomi Mi 8 Questions & Answers] iainmann:
A way of getting WiFi calling on some phones is to use Nova Launcher and its Edit Shortcut setting for icons.

Long press an icon > Edit Shortcut > select Swipe Action > scroll across to Shortcuts > swipe down list to Settings and select > swipe down list to WiFi calling and select.

It should mean that when you swipe up on the icon, you'll get a toggle to switch WiFi Calling on or off. I've tried it with Samsung and Huawei, which have both been missing the WiFi calling setting and it's worked.
[Xiaomi Mi 8 Questions & Answers] baddevil2:
Activating the options for VoWifi is not the problem but you need the right ROM or an other operator profile.
[Xiaomi Mi 8 Questions & Answers] slider86:
Guys I think it depends if your operator supports it or not. I checked my operator's supported list for vowifi and all they had were most commonly used phones like iphones, galaxy s series, lg and etc but no xiaomi at all. So what if smo can come up with a way to fool cell operators for example like as we are using a samsung galaxy s9? I believe if this could be done, enabling vowifi on our end could make it work.
[Xiaomi Mi 8 Questions & Answers] baddevil2:
It depends on if your operator has a whitelist of phones which are allowed to use VoWifi or if your operator allows all phones to use this. In germany all three big operators have no whitelisting, all of them allows every device to use VoWifi.

VoWifi works even with MIUI, but you have to select a working operator profile with PDC. Know it from some poco and mi8 users with MIUI(.eu).

And VoWifi ist working great on Mi8, don't want to miss it anymore.

VoWifi on MI 8

Hello,

Thank you so much for the high quality information got on xdadevelopers...

I'm struggling hard to get a solution to enable wifi calling on my MI 8 since about a month ago the 4G antenna is dammaged in my rural area in the Vexin near GISORS 27 France.

SFR has not yet fixed the issue and the result is in my house i cannot mke a call or receive a call. I called SFR provider and they had already enabled 4G VOLTE + VoWifi.

The problem is that the latest MIU 10.1.2 eu.ROM is not yet VoWifi aware...

So i already had the Boatloader unlocked and i may install TWRP and then Magisk to enable VoWifi...

Please let me know should Magisk be mandatory to get succes.

Thank you in advance

Regards
[Xiaomi Mi 8 Questions & Answers] Memarco:
But how? If i do it, nothing changes. I am on MIUI 10, latest global rom wich came as ota. VoLTE is working but Wifi Calling is still not there. When i am in Flight Mode and activate wifi it wont make a call.

Just bought that phone, after i am not comfortable with the huawei p20, but on that i had volte and wifi-calling directly from the start after all OTA Updates.

I am also on T-mobile Germany
[Xiaomi Mi 8 Questions & Answers] baddevil2:
For german providers (for T-Mobile and o2) on MIUI you need to change the operator profile using PDC to "DT_Greece" otherwise it should not work.

For more information google "volte-und-wificalling-xiaomi hubo". The first entry (it's android-hubo forum) there is a guide on how to enable it on Xiaomi phones (poco and mi8).

Otherwise you can PN me and I will send you the link to it.
[Xiaomi Mi 8 Questions & Answers] baddevil2:
MIUI has built in VoWifi support. But the default selected operator profiles are wrong. (In germany). If you want to stay on MIUI the only possible solution is to change operator profile with Qualcomm PDC tool.

[Xiaomi Mi 8 Questions & Answers] Memarco:
Hello, so only with Root ist possible to get Wi-Fi calling to work at the moment?
[Xiaomi Mi 8 Questions & Answers] baddevil2:
Yes you need root for it, because you have to enable debug mode on your device to get a connection with PDC:

su
setprop sys.usb.config diag,serial_cdev,rmnet,adb

[MENTION=2112646]baddevil2[/MENTION] you have written "For german providers (for T-Mobile and o2) on MIUI you need to change the operator profile using PDC to "DT_Greece" otherwise it should not work." what about vodafone germany? will it also work with them? thanks!

Nvm. just read the whole thread. So should work with Vodafone as well by rooting and flashing another rom.. will maybe try it in a few days/weeks, dont want to flash right now. Sucks that Xiaomi still didnt manage it to provide it just out of the box working with MIUI. :/
[Xiaomi Mi 8 Questions & Answers] baddevil2:
Never tried PDC with MIUI, so I can't tell you if it works for vodafone germany. I know only that it works for o2 and telekom germany.

But you can try yourself, but make a backup of your efs partition before.

[Xiaomi Mi 8 Questions & Answers] bergui45:
where can i get a tuto for TWRP + Magisk + Root on my MI 8 to enable VoWifi?

Thank you in advance
[Xiaomi Mi 8 Questions & Answers] baddevil2:
For TWRP, root and magisk there are many threads here.

If you are using MIUI -> You have to select the correct operator profile in PDC

If you are using Custom Rom -> It depends on custom rom if you need Magisk-Module to enable VoWifi (On latest Havoc I didn't need it) and if VoWifi is supported by Custom Rom.
[Xiaomi Mi 8 Questions & Answers] Danchibald:
Thank you for confirmation.

I suppose that this is code (like *#*#86583#*#* for VoLTE), but i said "lets go to check and confirm on internet".

Must my MI 8 be rooted after installing TWRP before installing HAVOC-OS-v2.1.20190116-enchilada-official.zip downloaded from Sourceforge?
[Xiaomi Mi 8 Questions & Answers] baddevil2:
You have to install TWRP to install any custom rom.

You have to install Magisk after installing a custom rom.

ROM -> (dm-verity if you don't want encryption) -> Magisk.

!!! I am not responsible for any damage on your device. There are many instructions on xda on how to install a Custom Rom on Mi8. Or just google. Or look into Havoc Thread there is a little description, too.

So if you turn Miui optimazation off in the developer Settings, then dial in the *#*#869434#*# it will show Vo-wifi carrier check disabled. Now i got The Wifi Calling Settings in the same Place as the VoLTE Settings. But when i'm in flight mode, with wifi turned on, it sadly still doesnt work. Any suggestions?
[Xiaomi Mi 8 Questions & Answers] baddevil2:
- Call *#*#4636#*#*

- Open telephone information (Telefoninformation in german)

- Then select three dots on the upper right

- Select "IMS status" (IMS-Dienststatus in german)

IMS-Register/IMS-Registrierung needs to be "Registered" and Voice-over-WLAN needs to be "Available" (Verfügbar in german).

If Voice over WLAN shows not available (Nicht verfügbar) then your phone is not registered in/on IMS (for VoWifi) of your operator.

Hey [MENTION=2112646]baddevil2[/MENTION]!

I would like to use WifiCalling on my Mi 8 too with o2 Germany. LineageOS 16 and latest TWRP are already installed and with regard to IMS Registration every single service works fine and is shown as registred - except Wifi Calling. The toggle shows that it's activated, but it's not shown as "available".

What can I do? Do I really have to root the device?

Is there any possibility to make some config changes to the ROM-zipfile that could make that service work? (There must be!) As you probably know, LOS 17.1 will be released for dipper in a few days and therfore it's anyway necessary to reflash the device. Do you see any chance to solve this wifi calling issue in the same process? I would like to understand, what and where that has to be configured so that it's working in the End.
[Xiaomi Mi 8 Questions & Answers] double-gee:
Here comes the explanation how to enable WifiCalling on the MI8 for Deutsche Telekom (Germany) using the stock rom:

Assumption: device rooted, twrp bootable or installed, IMSI-codes to disable carrier check and vowifi check applied.

Preparation: Install Qualcoom tool and drivers.

Create a backup of everything in twrp.

Follow these steps:

1. unlock bootloader

2. install twrp

3. Install magisk or another su tool to gain root

4. enable developer mode

5. enable ADB debugging over usb

[If you rooted already, start here]

6. connect using "adb shell"

7. type "su" to gain root

8. type "setprop sys.usb.config diag,serial_cdev,rmnet,adb" to let the qualcoomm tool access the EFS partition

9. start the qualcomm tool "PDC" on your pc.

10. click on "Device" and select yours

You will now see all volte/carrierprofiles and note that a default commercial profile is activated

11. click on the profil "Germany-VoLTE-Vodafone" with the right mouse button and chose SetSelectedConfig: SUB0

12. Select it and click on activate.

13. You should get rid of all other profiles by deleting one after another except the one selected above and the two default profiles that cannot be deleted.

14. on your mobile disble VoWIFI-Carrier check by typing *#*#869434#*#* in the phone app. [If VoLTE wasn't enabled, do so before by dialing *#*#86583#*#*]

15. on your mobile go to settings, sim, Telekom...and activate Wlan-Calling

If it was enabled before, disable and reenable.

16. done.

Go itno flight mode, enable wlan, wait 5-10 seconds and make a call. After hanging up the mi phone app will show whether you were using volte or vowifi.

If it didn't work:

- reboot

- check in the pdc tool if the proper profile was enabled

- disable vowifi and reenable-
