Voip answered call not audible.

[JaspreetiOSDev]

After app killed and screen locked voip voice not audible. If you have any update please let us know.

[ismailgulek]

On which version did you experience this?

[Shamam22]

Element V1.2.1.
I have the same problem.

[ismailgulek]

I'm not able to reproduce this on 1.2.1. Can you give more details, like what's the other client and what is the version of that? And if you can send a bug report, that'd be helpful.

[JaspreetiOSDev]

You can reproduce it by: - Login in the app - Kill App - Screen lock - call this phone from another device and you will get call and accept the call and voice not audible.

I am not sure if this is the same issue but we noticed a significant degradation in audio connection establishment after 1.2.1 update. In conditions when connection is only possible with TURN server it now requires multiple redial attempts in both directions to get audio going through.

2 clients on IOS version RIOT / 1.2.1. The call passes the voice no.
If the client version is less than 1.2.0, the voice works. It works fine with clients on Android.
If the first client has the RIOT / 1.2.1 version, the second RIOTNSE / 1.2.1 - the voice works.
If you put it on hold and return when the voice is not working, a voice appears.

I was using 1.0.14 version

I'm only able to repro this due to #1934 right now. Assuming the issue you see is not the same, we should dig more into this.

@ismailgulek I have enable microphone in app delegate so I think it is not related to microphone issue. But I am getting voice missing every time while receiving call. after kill app and locked screen.

[ismailgulek]

I could repro this guys, investigating on WebRTC level.

[JaspreetiOSDev]

I have implemented all changes provided by you but on first call after kill app and locked screen. No voice coming.

[ismailgulek]

@JaspreetiOSDev you need to implement them on both sides of the call.

[JaspreetiOSDev]

@ismailgulek I am calling to iOS Device from Web app.

[JaspreetiOSDev]

@ismailgulek Now when I am accepting call from iOS than ringer is continuously ringing on web app end after app kill and locked screen.

[JaspreetiOSDev]

@ismailgulek When app killed and phone locked then in MXCall.m class following condition is always false:-

• (void)answer

    if (self.state == MXCallStateRinging
        || (self.callSignalingRoom.summary.isEncrypted && self.state == MXCallStateCreateAnswer))
    {
  

This condition is always false in answer method that's why I am not able to answer the call and at the web end ringer in ringing continuously. Any feedback on this. Please let me know

[ismailgulek]

@JaspreetiOSDev can you provide your client logs please? A bug report would be helpful after seeing the issue.

[JaspreetSingh1986]

@ismailgulek I Checked this issue many time and some time this method not giving response-

    [peerConnection       setRemoteDescription:sessionDescription   completionHandler:^(NSError * _Nullable error) {

means I am not getting success and error in this method after the call.

after app killed close app and get call and answer the call and some time this method giving success response and sometime it is not giving any response and stuck. Completion handler not calling some time. I have also check check sessionDescription and sdp for this method it is also valid.

[JaspreetiOSDev]

@ismailgulek any update on above comment actually I am getting this issue on every time from iOS to iOS call. not able to pick call if app killed and locked screen.

[ismailgulek]

Please test on develop.element.io as it includes some bug fixes too on the call connectivity side, otherwise we should wait for Element iOS 1.2.3 to be available for everyone.

[JaspreetiOSDev]

Actually Web to iOS is working fine audio configure properly but iOS to iOS it is showing Unconfigure audio session and call disconnect when accept the call.

[JaspreetiOSDev]

@ismailgulek

     [peerConnection       setRemoteDescription:sessionDescription   completionHandler:^(NSError * _Nullable error) {

this method is not executing, that's why iOS user is not able to answer the call.

Any idea about this.
