VoLTE: no Caller-ID - Xiaomi Mi A2 / 6X Questions & Answers

Hi, when I activate VoLTE in my device, incoming calls do not show the caller-ID (with 3G there is no problem). It always says "unknown number". Does anyone else have this problem too? How can I fix this?

I had the same problem. I disabled VoLTE as this is my work phone and I need callerid. Please let me know if you find anything out.

Got the Pie update, now VoLTE works and the caller-ID is shown correctly.

Can't make calls

For some reason I can't make calls. I'm using the stock dialer on a stock rooted ROM (see sig).
I dial a number and it looks like it's working (the call timer starts counting and what not) but it never actually calls. Just silence.
I haven't been able to test receiving calls yet but I did at least get some missed calls earlier when I was away from my phone (it was when I tried to return those calls that I discovered this problem).
I'm on Verizon. I have LTE set as my "Preferred Network Type" in Cellular Settings. Data works fine in both LTE and 3G areas. Texts work fine. Just calling seems broken.
Had anyone seen or heard of this? I searched this forum but didn't find anything.
poor connectivity on WIFI network on nexus 6
I also face the problem if not able to make/receive calls when WIFI network is activated.

Are you on the 98r radio? That's the one that ships with the Verizon branded Nexus devices and is different from the radios in the other 5.1 builds.

G4 sending calls straight to voicemail!

I've made sure that call reject list is set to off. For whatever reason though, when a call comes into my G4, the call app displays for about a second and then it refuses the call automatically causing it to go straight to voicemail. Anybody experience this issue?

I don't have this issue.
1) Is this T-Mobile branded phone?
2) What is the coverage or does this issue occur only in some places?
3) Are the settings correct under "mobile networks"?
4) Is Wifi calling feature is on/off under call settings?

Interesting. I have tested my phone vs 4G and LTE connection, don't have any of your phone issues. Couple of things came to my mind. If your sim card is not fresh, try replacing it or ask a friend if he/she has newer sim card and try to make few calls. Another important thing is VoLTE, it is also in the call options above wifi calling. IF VoLTE is on, try to turn it off and user your phone for a day and see.

I agree with this. I turned off VoLTE and my calling got better.
Sent from my LG-H811 using XDA Free mobile app
Thanks for all the suggestions guys. I tried them all. In the end, I narrowed the issue down to google voice. When I first got my G4 I tried setting google voice to be the primary voicemail service. I'm on a postpaid plan, so there shouldn't have been any issues. Not sure what happened, but it obviously screwed something up. If people call my T-Mobile number directly the call goes through just fine. If they call my GV number, the voicemail picks up just before the first ring on my G4. The caller ID pops up and then disappears as if I touch the decline button. I've tried setting my T-Mobile voice mail back to default and called T-Mobile. The problem is not persistent. It is intermittent.

My phone sometimes doesn't receive calls or texts.

My phone periodically doesn't receive calls or texts. I've tried resetting it. The calls don't show up in my missed calls but the voicemails do show up. I'm using the international version of the Note 8. Anyone know a fix?
Does the data drop out too when this happens? Try taking your sim card in and out again. Might be a problem there.
Have you got any do not disturb settings on?

Nope the data stays on. Outgoing calls work fine as well. All the do not disturb stuff seems to be off.

Are you rooted or did you install any custom roms, etc.?
I have had this issue with several phones, the culprit has been always the type of connection, sometimes even if full bars showing, I have to switch to 2g or 3g, 4g and 3g having the issue, 2g working always fine, dont know why, but I have learned to live this way, this happening since my S3, so, In my case is carrier signal fault

What networks are you both on? If it is the same, that may be your answer...
I would check with the network to see if the masts are under maintenance.
I wrote a post here in March 2018, but, some time later the issue diasppeared, from june, all is fine, in the end, I think it was the carrier that was working on the transition to 4.5G to implement their VoLte calls service
I have this same issue and with the same phone as well
I have the same issue, and i think it as to be with the position of the phone... when its down missed more than when its on vertical... could be just coicidence but its the only thing that i note

No Incoming calls when on WIFI... Help!

Hi Everyone. I have the Pro - CLT-L04 on MetroPCS .
I found an issue and wanted to know if anyone else had this issue.
When on WIFI, I do not receive any INCOMING calls, people tell it goes straight to voicemail. Soon as I am off wifi, it works fine. I can make calls, but cannot receive them. This happens about 90% of the I am on wifi.
There are no setting to play around regarding WIFI calling or any of that.
Any suggestions?
Same here. Orange wifi calls in belgium.

I don't have the issue, but it sounds like it could be related to VoLTE or Wi-Fi calling.
Try to turn Wi-Fi calling on or off and see if it might help.

WiFi Calling on Mi 9 Lite

Hey Everyone,
Have any of you managed to get WiFi Calling working on this device without root?
I'm considering upgrading to this phone from my flawless Redmi Note 7.
However, the only feature I would need confirmation works is the WiFi calling.
Is this working on this device without root?
If yes, does anyone know if WiFi calling can work on TMobile?
I am using WiFi calling and VoLTE on T-Mobile in the US. I followed the directions on the thread below. When I ran the *#*#*****#*#* code, it gives a message about VoWifi/LTE carrier check enabled or disabled. After making sure the APN was correct (especially the APN Type), enter the code until it says that the VoWiFi/LTE check is DISABLED. Once it is disabled, you should see the option to enable WiFi calling and VoLTE in the SIM card settings. It will then show the status during calls whether it is a WiFi call or VoLTE call. It may require a reboot after the codes are entered.

Thanks Man!
I appreciate your prompt and thorough response.
I haven't been able to get WiFi calling working on my Redmi Note 7 and tried just about everything. (Outside of root)
Now that you've said that I have hope I'll get WiFi calling working on the Mi Lite 9 and think I may get one!
May I ask if you're rooted?
Also which firmware do you have?
