Receive / Make Calls Whilst Using Gprs/edge

Whenever my friend is connected to net on a laptop using a WM6.1 machine with Internet sharing on a USB link and GPRS/Edge Internet connection she gets a Voicemail reply to any callers? Is this a problem with the phone or GSM provider.
It´s a network thing. Some providers set higher priorities to voice calls, so an active GPRS data connection is interrupted, others (like the one I have) unfortunately send incoming calls to voicemail and hold the data connection active.
Thought as much, thanks for the heads up.

[Q] Can't receive calls while on 2g

Hello,
I have my phone for few weeks already and today i noticed one major issue. I will try to explain everything as clear as it is possible.
While i am on 3g network, there are no problems at all. I can make a call, i can receive a call, i can receive SMS etc... Everything works as it should be.
When i switch to 2g that's when the problem comes in. In the first 15 seconds after switching to 2g, i can operate my phone as in 3g - i can send and receive calls, i can send and receive SMS'es. After 15 seconds there is no ability to receive any call. The caller alway hears the same song: "the phone you are trying to reach is either turned off or out of radio coverage...". Also no SMS'es can reach my phone. Despite of this, i can send a call any time i want...
There's one thing i've noticed. When i turn my mobile data on - everything works just fine (you should be familiar with turning off mobile data function), but this is unacceptable to my mind. It seems that when i want to receive a call, i should be on 3g (doesn't matter if mobile data is turned off or on), or on 2g but with mobile data turned on...
I did one test - changed the APN's entry to a messy one, and left the mobile data on. Still wasn't able to receive any calls. Thats leads to a statement: while on to 2g, i have to be connected to the internet to receive a call, while on 3g, i can disconnect form the internet and still be able to receive all calls.
Additional info: HTC Desire - unbranded, non-rooted, stock ROM.
Can anyone help me to solve this issue?
It seems this problem only appears at home. At work (15 miles away form home) i can be on 2G and still able to receive incoming calls... Any ideas?

wifi calling - No voice on incoming calls

My device: T mobile s4 SGH-M919 using stock rom Android 4.4.4 with all OTA updates. Phone was moved to MetoPCS a year ago.
There is no coverage at my home so I rely on wifi calling to make and receive calls. For the last year it has worked just fine but in the last week I began having a very frustrating problem:
If I MAKE a call over the wifi, no problem I can hear them and they can hear me.
If I RECEIVE a call over wifi, I can hear them but they CANNOT hear me.
When I am not on wifi calling (ie using cell), everything works perfectly both making and receiving calls.
I researched the problem and this is what I have tried so far:
1. connecting to different wifi connections in entirely different locations - same problem
2. using bluetooth headphones or speaker instead of the mike - same problem
3. disabling Google Now Voice on every screen - same problem
4. factory reset - same problem
5. made sure I do not have any phone recorder apps installed (I do not)
6. switching the mute button on and off during a call - no change
Can someone please give me some advice or direct me to an answer. Needless to say Metropcs tech support is unable to solve the problem. For me this issue is not trival as I require wifi calling at home as I am in a rural area with no service.
Thank you
This happens to me as well. However, if i am to say "answer", and allow the voice command to answer the call it works properly but starts the call in speaker mode. Then you just turn off speaker, and conduct the call normally.
This has happened to me with most of the roms i have tried.
Haven't you tried on regular call? You listed no coverage in your area.. but, it should be some where 10-20miles away your area..

Yes, If I drive to a covered area and am not on wireless the calls work perfectly in both directions.
Do you figure out yet? I get a sch-m919 has reversal problem of yours. It make wifi call fine. When make regular phone call, they can't hear me and I get hear them. I guess, we have to try out the custom rom.

Call recording with voip calls?

I have t-mobiles wifi calling and was wondering if there's a way to record calls made over wifi calling? or whatsapp?
I know there are apps that record calls over cellular network.

Call issues

Hello
Recently I been having call issues when making calls, the call recipient doesn't hear me or hears me at the beggining of the conversation then stops hearing me. This never happens when I receive calls and always happens around my apartment or in the apartment. I'm on a network with Voip and I use Wifi calling but it's set to use 4g if Wifi is unstable. I tried turning both on and off but the problem persists and I've determined it's not an issue with wifi. Anyone experiencing something similar or has any ideas what could be causing this?
