Call waiting doesn't notify of incoming call during a call

Hello, I have a small problem with my XZ. It's currently running 4.2.2 with build number 10.3.A.0.423.
The issue I'm facing with, is that when I am in a call and someone else calls me there is no warning sound that another person is calling me. The reject or answer call appears but there is no actual sound to announce that another person is calling me.
I have tried without any luck the following:
- checked/unchecked the call waiting option = it didn't work, if the option is unchecked than the person that tries to call me while I am on call with someone else gets a busy line, so in this case the option works as expected
- used pc companion to restore 4.2.2 as I thought that maybe some app i installed messed up this option = this also didn't work as after the fresh restore there was still no sound while I was in call with another person while someone else called me
So my question is that is this a bug of 4.2.2, does anyone else know of this issue? I goggled this problem without any luck in finding an answer.
Any suggestions or ideas?

Nice to see that the thread got 94 views but no reply. Am I the only one with this problem?
Can someone with the same firmware as mine test the behavior described by me? That way I could find out if it's a 4.2.2 bug or another issue.

In call sound problem

I have in call sound problems.
When I reboot I can sometimes place one call without problems for as long as I want.
Other calls after that I have no sound, can't hear the call tone and other parties can't hear me.
Also incoming calls, i hear the phone ring but when i answer the other party can't hear me and i can't hear the other party.
The settings for sounds in the accessibility menu and noise reduction etc were off and stayed off. (other forum tips)
I also tried numerous factory resets with no avail
Can someone give me a hint how to fix it?
I have stock 4.2.2 International version of the S4 Active.
Baseband I9295XXUBMK2
Build JDQ39.I9295XXUBMK2
Kernel 3.4.0-2015525

Headset
I tried a different option. I can call with my bluetooth headset.
When i switch to speaker the in call sound drops. giong back to headset will not activate in call sound.

Same Here
The same happens to me. Only the bluetooth option works every time. I have tried several firmware and kernel versions and nothing has changed.
There is a workaround that I could find but it is totally impractical: http://forum.xda-developers.com/showthread.php?t=2371034
In forums for models / ROMs with a lot more users than this one (Nexus / CM) people with 4.2.2-based firmware versions there are many posts describing what could seems to be the exact same problem, which they have been able to fix via baseband updates or custom patches, but that does not really seems to be an option for the S4 Active...

Same problem with my SGS4A. I was on i9295XXUBMK2, tried to update using the phone update option, which rendered my phone unusable. Flashed new stock ROM i9295XXUBMK3, now I can use the phone, although sound problem persists.
Making a call: reboot, call
Receiving a call: answer, hang-up, reboot, call back
Anyone with 4.3 that has this problem on SGS3, SGS4 or SGS4A?
Edit 21.8.2014
I had the speaker changed last week and so far no problems. I am slowly getting confident that I can rely on S4A as a phone also, not just tiny surf tablet.

I have same phone, never got this pb. However I got some SD card issues after updating to KitKat...

Partial solution... for me at least
Hi guys ,
having same issue, disabling 4G option solves my problem. But it-s impractic cause I want to use the 4g... in a huawei phone I solved same issue by disabling an option of "mobile data always on"
Don't know how it's related...

Same issue for me. I made lots of research with no results. Nobody knows...

same problem here with no solution yet

same problem with in call and out call .... searched a lot about solution and no solution yet

I had a similar issue with bluetooth calls. First call would be fine, but after that I couldn't hear the other person on the line and they couldn't hear me. It turned out to be some kind of incompatibility with the Google "OK Google" detection with Galaxy S4-based phones. If I disabled it from detecting "From any screen", this seemed to correct the problem. However the setting might return on application updates. I would recommend trying that and see if it makes a difference. If it's not that, then I don't really know how to help you. I moved on from that phone over a year ago and have been happier ever since.

Incoming messages and call problem

Hey. Hope you guys well. I have sony xperia z1 c6903 running 4.4.2 (api 17) global software with generic user. I thing it has network problem but I don't know whether it's software or hardware issue.
Problem:
When someone calls me it says "your dialed number is switched off" even i am unable to send or receive messages
And when i call someone it gets connected and starts receiving/sending pending messages.
Do I need to upgrade software if yes then please provide stock rom 5.1.1 link.
Thanks in Advance.

Note 9 WiFi Calling - can`t make calls but receiving works.

Hi there.
I have Note 9 without any brand. Updated to newest firmware that existed and about two updates ago there was problem - i cant make any calls. Restarts one helps, and other time don`t help at all. And now - it was no use to restart phone because of this problem. I felt that it might be this problem and i turned off this option and tried to make call - and nothing. Only when i restarted phone again - i can make phone calls normally like before. This problem exists not everytime, it looks like when i make call to my second phone it is only "connecting..." at my note9, and other phone is ringing. And there is two kind of behavior, first - in note i cant hear anything, just this "connecting..." message, and other phone after few seconds hangs up and ask about reconnect. And second - after few seconds after receiving call it finally works but it have take some time between receiving call at second phone and hearing anything. Its lottery.
Now i have this option disabled, phone is restarted and now i can make calls. I contacted Samsung via chat (samsung members app) and via Twitter and they said to me to go to their service to diagnose or sth, but i know what i will hear at service: "please reset your phone to factory settings and if then this issue will be present we will take your phone and try to repair it" but i don`t want to do this because of all this configuration and hours of clicking... I dont like to do this when i dont have to.
So my question - do you have similar or the same problem? Is WiFi calling have anything to do with sim provider?

Well need a few things to be able to help.
Carrier?
Model? I'm guessing N960I1?
What is the firmware version you're on?

And I'm assuming the carrier Support Wi-Fi calling right? It may be a provisioning issue. You should try contacting your carrier and verify Wi-Fi calling is a feature and that they support it on your device. They should also be able to help you activate it if they support it.

I wrote that it was working normally before, and now it stops. I`ve had this thing working.

In calls, receiver can only hear me if speakerphone is on

Bit of a disappointment that the basic function of the phone is not working correctly!
In order to be heard on a call I need to switch on speakerphone. Anyone else had this issue?
Tried wiping the cache and restarting the device.
Verified that the microphone is working. I can make calls with Messenger, WhatsApp etc.
Upon hanging up, there is an audible pop on the receiver end during my tests.
Affects both incoming and outgoing calls.
NX627J_V1AMB with build NX627J_ENCommon_V2.03. The phone came with V1.03 but did not test calling.
Phone app build version 11.0.
Any help much appreciated.

Hi,
Ordered my phone with EU distribution and came with NX627J_ENCommon_V2.03 and I don't have such a problem. Maybe flashing went wrong? There are many users experiencing issues after flashing.

Hi, this was after flashing but I've since debricked (using https://forum.xda-developers.com/nubia-z20/how-to/tool-nubia-z20-unbirck-tool-t4009227) so believe I'm on the correct firmware. If someone can confirm this is the case that would be useful otherwise I will try and flash firmware
