flutter run -d chrome is lapse

Call fails with Asterisk 16 -> Reason: SIP ;cause=488; text="Not Acceptable Here"

Asterisk and Flutter logs attached with full SIP trace.

This change in RTCSession.dart fixes this, but is just a hack and a proper fix is required.

//TODO: Commented out because this seems to cause errors with Asterisk

//await this._connection.setRemoteDescription(answer);

this line in the logs is important:

I/flutter (15658): 09:12:30.029 (+0:00:29.733517) [DartSIP:RTCSession] ERROR: emit "peerconnection:setremotedescriptionfailed" [error:Unable to RTCPeerConnection::setRemoteDescription: Failed to set remote answer sdp: Called in wrong state: kStable]

Asterisk16-5PjSip.log

DartSipUaDemo.log

emit "peerconnection:setremotedescriptionfailed" [error:InvalidStateError: Failed

Working in both android and iOS but in chrome not working.

Hello @ghenry ,

When i try with one to one SIP call. i am not getting call another side. for example A call to B, B is not receiving any event. But when User A terminate call or timeout, suddenly B will get incoming call and instant it will hang up call automatically.

So can you give me any reason why this happening. Any changes required in code or server side ?

I am giving call logs which i have tried call.

Describe the bug
When starting a call, there's a very long delay until the actual call is made. It seems fine at ae529ee, but is slow at 46f74b0.

Expected behavior
Calls should work quicker, as in previous versions of the library.

@cloudwebrtc
Hello cloudwebrtc community,

We have checked this demo by installing in android and iOS Device and we have also configured server.
We have checked your demo all functionality working properly related to SIP call and video call.

But i have some suggestion to improve this demo.

1. Sometime UI not responsible and hangup in some screens.
2. When i start to call another user, timer will start automatically before call pick up, in that place you have to place in progress call or something like that.
3. When we try one to one call sometimes registration issues are there, you need to registered again.

So i have hope you will implement my suggestion in your current demo. It will help many users who are using this demo.

Thanks

When I press the green call button it always fails on the first attempt. It times out after 30 seconds or more and then when I press the call button again it usually connects the second time. However it often takes takes three attempts to make the call. The initial call attempt fails every time. Same for other users. We are connecting to a FreeSwitch server from android devices. Latest version of Flutter on the beta channel.

In the logs there is no error message. On both failed and successful attempts the communication process between client and server flows the same up to the point where a "SIP/2.0 100 Trying” message should be received. This is never received on failed attempts.

We would like all calls to connect on the first attempt. Any help would be appreciated.
Stack traces of both a failed and a successful attempt are below:

1. Go to ' Run Debug Configuration '
2. Click on flutter '' then select Name class it as you want , below you will get option to set endpoint of dart.
3. You will get dialog with 2 tab select class or search dart endpoint
4. Error dart class don't have main function

Expected behaviour
A class must be name friendly to find proper dart endpoints

System Information()
Flutter SDK Version:
Target OS and Version:Android 10 , IOS 13.1
Host OS and Version:Ubuntu 18 LTS

Describe the bug

Audio call terminates after 1 second.
Also, library didn't handle any inbound calls (I even don't see any SIP log).

To Reproduce
Steps to reproduce the behavior:

1. Create Telnyx account
2. Make SIP calls to any ordinary phone number. For example audio call to sip:[email protected]
3. Call starts successfully
4. I hear the voice from both sides
5. Call terminates with one of the several errors: call failed with cause: Code: [488], Cause: Bad Media Description, Reason: Not Acceptable Here or call failed with cause: Code: [503], Cause: SIP Failure Code, Reason: Service Unavailable

Log files:
android_call_interupted.txt
ios_call_interupted.txt

Expected behavior
Calls shouldn't terminate after 1 second

System Infomation()
Flutter SDK Version: 1.13.7-pre.26
Target OS and Version: Android 9 / iOS 13
Host OS and Version: Ubuntu 19.04 / Mac Os Mojave

I am working on Flutter client for Telnyx. It helps connect VoIP and ordinary phones. SIP related docs - https://sip.telnyx.com/. It looks like library incompatibility (implementation or config) with Telnyx SIP/WebRTC. I am ready to fix everything myself but I don't have experience with SIP/WebRTC and I need direction where to start debugging this issue.

PM me If you need Telnyx credentials to test.

Thanks for good SIP library!

Describe the bug
I connected one mobile device to WIFI connection and other device to mobile data. Then I make a call and accept from the other end. Signaling is working fine, but streaming is not happening. The same issue was reported in flutter webRTC repository also. As described in there I used 'viagenie' turn server and tried. But it still failing. Please give this a look.

To Reproduce

1. Get two devices. Connect one device with WIFI and the other device with mobile data.
2. Then make a call from one end and you will see streaming is not happening.

Describe the bug
Flutter WEB version Does not seems to work with SignalWire nor Telnyx

JsSIP works with SignalWire

To Reproduce
Steps to reproduce the behavior:

0. Fire the example for Flutter Web:

flutter channel beta
flutter upgrade
flutter config --enable-web
git clone https://github.com/cloudwebrtc/dart-sip-ua.git
cd ./dart-sip-ua/example
flutter run -d chrome

1. Create SignalWire account, get a verified number
2. Follow this tutorial to call the verified number

Registering logs gives:
registered => Code: [200], Cause: registered, Reason: OK

but calling does not works

When calling, last log line is :
[2020-02-08 21:50:02.997] Level.debug null ::: createLocalDescription()

Expected behavior
Receiving a call on my mobile

Good day,

Having an issue with setting up the client to setup calls.
Call goes through as indicated in file attached, but dart-ua-sip works for est. 2 Seconds then client returns [488]

testing on tryit.jssip.net works perfectly
Where could the problem be?

When initiating a call there is a sizable delay (up to 15 seconds).

I suspect this is a bug in the Asterisk Secure Web Sockets (WSS) handling, but if someone not using asterisk could test and check this issue with WSS would be appreciated so I can eliminate Dart as the possible source.

I try to connect to webrtc server but client try to connect using ws and not webtc?

After running the shell create command I get an error on running the flutter run command

How do I get it working?

Hi, we have the use case that an FCM notification will wake up the app to accept a call. Now, because of the WebRTC loading time, when the app is terminated it takes too long to start up again, and the call can't be accepted anymore.

After removing the dart-sip-ua dependency the loading time is fine again. So a fix might be to load the WebRTC library on demand, or perhaps something else.

Thanks!

When trying to make a call, I am getting the error call failed with cause: Code: [488], Cause: Incompatible SDP, Reason: Not Acceptable Here. I emailed my provider, Telnyx, and they responded...

"So a 488 response is generally related to a bad media parameter in your SIP INVITEs SDP body, which our system does not like.
Upon inspection, your SDP is quite big and you can see the pasted version below.
It's hard to tell which one's could be the parameters we don't like but what catches my attention straight away are the candidates.
it appears this SIP Client is listing candidates in IPV6 and I'm pretty sure we don't support this.
The other candidate, that is IPV4, is a private IP address as-well.
If you can remove the IPV6 candidates or change them into public IPV4 addresses, that should do the trick."

Is it possible to force IPV4 use in the config when initiating a call? Thanks!

Try to create grammar_parser with dart peg, but I get a problem that is not supported by the "i" syntax. This parameter is used to ignore the case of the matched string.

https://github.com/cloudwebrtc/peg

SIP_Version       = "SIP"i "/" DIGIT + "." DIGIT + {
                    data.sip_version = input.substring(pos, offset); }

Here is a patch for pegjs, and the dart version of peg requires a patch.

Hi
Not an issue with dart-sip-ua but if anyone can help...

For those who used dart-sip-ua with Flutter Web, did you run into problem with access to the microphone in Chrome?

I described the issue in Flutter issues

Any help appreciated if you did run into this problem too

emit "peerconnection:setremotedescriptionfailed" [error:Unable to RTCPeerConnection::setRemoteDescription: Error Failed to set remote offer sdp: The order of m-lines in subsequent offer doesn't match order from previous offer/answer.]<…> [VERBOSE-2:ui_dart_state.cc(157)] Unhandled Exception: type 'TypeError' is not a subtype of type 'String'

When trying to start a call, the app is crashing and not returning any meaningful error.

I am running _helper.call(handle, true);. It looks like it is starting, but crashing when trying to start a new newRTCSession. Register state looks good, returning RegristrationStateEnum.REGISTERED. Building for iOS and running on an iPhone. Has anyone else run into this issue and know how to resolve it?

Running this in example/scripts puts the permissions after the application xml tag in android/app/src/main/AndroidManifest.xml causing a failed build.

flutter webrtc uses minSDK version 18 so this example app won't run until you change the minSDK version on android

When on a video call with https://tryit.jssip.net/ and you click Hold/pause in your browser, the in-screen controls on the Flutter side disappear.

Thanks.

Hi, this is probably not enough information, but maybe you can point me into the right direction. When I receive a call, everything goes through up till ACK, until the call immediately gets canceled with a BYE, and these notable headers:

X-Asterisk-HangupCause: Bearer capability not available
X-Asterisk-HangupCauseCode: 58

Any idea what the reason could be? Thanks!

Thought I should let you know what I'm working on.

I feel that sip_ua_ helper belongs in the main lib, not the example and that there is far to much of the libs internals exposed through it. So I am currently working on moving it and exposing the information that clients will need without exposing the sip stack internals. I'm also changing the messaging between sip ua helper and the example code to use a simple listener mechanism rather than the event manager.

I found an existing bug and have a fox for it where the Web socket doesn't close when stopping the sip stack.

On Monday I'm intending to fix the dtmf code. It currently breaks after a single dmf digit.

Looks like it?

如题··

I attempted to make a video calling between two clients using the web variant (for both clients) of the example app.
Freeswitch was used as the SIP/media server.

To Reproduce
Steps to reproduce the behavior:

1. Load app on client A and register with freeswitch server
2. Load app on client B and register with freeswitch server
3. Client A calls (clicking on video icon) client B
4. Client B receives incoming call, click to accept call
5. Call is disconnected

Expected behavior
I expected a video call to be established

System Infomation()
Flutter 1.14.6
Client A - Chrome (version 81.0.4044.62) running on Pixelbook (chromebook)
Client B - Chrome (version 80.0.3987) running on Android (version 9.0)

Further investigation revealed that it was failing when calling _connection.setRemoteDescription(answer) in rtc_session.dart because the RTCPeerConnection was in the incorrect signaling state (it was null), even though setLocalDescription had been called previously.

I then decided in rtc_session.dart to define a onSignalingState callback:

this._connection.onSignalState = (signalingState) {
    print('signalingState $signalingState');
}

But to my surprise when I re-ran the video call worked! Which I don't understand at all. I removed this code and re-ran and I was able to repeat the failure, and put the code back and it worked.

The video call was established and working, although there wasn't any audio, but I've not had time to investigate this issue.

Current progress:

• Basic unit test
• Integrated with flutter-webrtc
• Register/Un-Register
• Send Invite
• Recv Invite
• Hold/Unhold
• Dtmf send/recv
• Refer (Call Transfer)
• Message send/recv
• Re-Invite (audio/video call switch)
• Full-featured demo (android/ios flutter app)
