no sound on voice calls - mystery problem - G3 Q&A, Help & Troubleshooting

Hey! My wife has a t-mobile G3, stock non-rooted. It's running 6.0. She's had it for a year, and it's been fine (other than some wifi issues here and there). But in the last few weeks, she can no longer make calls.
The weird thing is the calls do "connect", but there's no sound either direction. For example, if she calls me, my phone will ring, but when I answer there is no sound either direction. Both of our phones show the call timer counting the seconds, as if they are both connected. If one of us hangs up, the other phone gets disconnected immediately---so the 2 phones are DO connect with each other, but no sound can pass. This happens with every number she calls.
I would have thought it might be a network problem, but she did a factory reset and it worked fine---until a few days later when it broke again. So I'm thinking it's software. Sometimes her phone will work for a few hours, but then it will stop working for a few days.
I've tried turning ON/OFF bluetooth, wifi, data, & wifi calling. I've tried changing to 2G network. I've tried different sound/noise settings. No change.
Any ideas?? Thanks

Nexus losing cell signal then cant make calls

Its now happened 4 times always in the same place and Im wondering if its an issue with the Nexus or my carrier (or a combination of both) it never happened with my old Sony Xperia SP (call still dropped on xperia but always could dial or be called).
I go through a small village and the signal drops so call ends. Phone shows signal so I try and call back and call instantly says 'call ended'. The other person cant contact me either.
3 times its worked by turning off the phone then restarting it, today I had to restart then toggle aeroplane mode a few times before I could call, all the while the phone showed signal.
Is there anyone else who has experienced this behaviour? Its only this one location ive had the issue but not being able to reestablish a call is a real pain and shouldnt be happening from what I can see.
Network is EE in the UK.
May be a little late to answer, but i have the same problem. Could you do something to solve this issue?

Calls going silent

I have been experiencing this problem with making some phone calls where it connects to the line I am calling, but it goes silent. They can hear me, but I can't hear them. I have found that it usually depends on who you are calling. I just did a test with a friend's cell phone and a land line. I called the land line 10 times in a row and there is never a problem. But when calling my friend's cell phone, it is random. Would go silent the first time, then be ok the next 2 times, then silent again, and so forth. Also, my friend's cell phone is set so that it only rings one time, and then the voice mail picks up. I know this from looking at the top right of the phone screen where it says "Dialing", and when the call connects, you will see a time counter. When the time counter is running, it is still silent.
I wiped the phone app cache and system caches, but the problem still occurs.
Any ideas why this is happening?

anybody having issues with wifi and mobile data (T-Mobile)

I'm getting tired of it, wifi disconnects and reconnects or flat out doesn't work, mobile data flat out doesn't work most times unless I reboot the phone for either of them to work. I'm rebooting about 4-5 times a day just to get either working. I'm at my wit's end and about to get rid of this thing as soon as I can.
I generally love this phone, but I'm seeing similar issues. WiFi says connected, but I don't get any data. I thought it was my network at first, but noticed other devices working. Tested network while my phone was acting like this, and my WiFi and network were working great.
Separately, my phone sometimes won't dial out. I use Google Voice, so I'm not sure if it's the phone or Google that's not working, but it's very frustrating. The dial screen comes up, then immediately disappears. No errors or anything to indicate that it ran into problems. The dial screen just flashes. Rebooting seems to fix that. But all very frustrating. Especially when I'm trying to call someone while driving. I don't want to have to look at the screen. I want to be able to tell the phone to call and know it's going to do it. Instead, I tell it to call, it confirms it will call, then nothing.

Network issue - Italian Career

Hello everyone,
I have a Xiaomi Mi 10T Lite which I use as a secondary phone.
I'm experiencing a serious issue which happens randomly during the day:
all of a sudden, especially after long sleeps, the phone seems completely isolated from the mobile network making it impossible to send/receive calls, although showing data coverage.
What I noticed during one of this episodes in the #*#*4636*#*# menu is that the phone is trying to connect to the preferred network NR/LTE/TDSCDMA/GSM/WCDMA.
Switching that to GSM/WCDMA/LTE (PRL) revives the connectivity.
Any idea on how this can happen?
Thank you
I too am face the similar issues. I am running PixelExperience 12.1. I use two India SIMs with WiFi calling support.
As you mentioned, after long sleeps, the phone is not able to make calls or connect to receiving calls. Sometime, the call gets disconnected as soon as we answer and won't be able to call back. If the phone connects, the call is completely silent. Disconnecting and calling back works sometimes but most times, call doesnt go through. Putting it on flight mode and back sometimes makes it work. Sometimes restarting makes it work. Either way, its really frustrating.
I tried look at logcat output but I am not able to figure out what is going wrong because of the volume of things happening at that time.
Which is the OS version and firmware you are on? Stock MIUI? Or custom rom?

Voice call issues on 18.1

Having an odd series of issues that might be device-specific (Pixel 3), but definitely isn't a problem with my hardware, as that was recently replaced and had the same issue.
Basically, what I see is:
- For 1-3 days after a reboot, the phone works perfectly. Data works as intended. Calls work as intended. My office area always sits on full bars, LTE.
- After a few days, suddenly I have no ability to make calls...but I can receive them fine. If I try to call anyone, it just sits on the dialing screen for 1-5 minutes and then hangs up or dials. Inbound calls are instantaneous and there are no data issues.
- When the dialing issue occurs, if I watch the signal meter, it will be full bars LTE, then 3G, then H+, then it will either dial or will briefly say there's no signal and hang up...the moment it hangs up, it goes back to LTE and data works fine again.
- Either rebooting the phone or turning on/off airplane mode will fix the problem for 1-3 more days.
- This issue happens even if I switch over to wifi calling and am on good wifi signal, which makes it even stranger!
- I've reinstalled and updated LOS a few times since this began and issue persists. I've tried with wifi on/off, wifi calling on/off, different locations, etc. I even briefly tried the official Google dialer app, as I had been using the stock LOS one. No change.
