When using OriginateWithId method, I pass the parameter variables as described in the article ("ARI Originate and SIP Headers").
In my case this dictionary:

new Dictionary<string, string>() 
{ {"SIPADDHEADER0", "custom-header-1:custom-value-1"}, {"SIPADDHEADER1", "custom-header-2:custom-value-2"} } 

JsonConvert serializes this into the format:
{"custom-header-1":"custom-value-1", "custom-header-2":"custom-value-2"}
But this format is not suitable, as documentation Asterisk ARI said:

The' variables ' key in the body object holds variable key/value pairs to set on the channel on creation. Other keys in the object body are interpreted as query parameters. Ex. { "endpoint": "SIP/Alice", "variables": { "CALLERID(name)": "Alice" } }

Necessary in the methods Originate and OriginateWithId instead of Dictionary<string, string> apply Dictionary<string, object> for serialize nested objects... How could have stated the problem, maybe there is a more rational decision... Please give me an example. Thank you.

I'm trying to add integration with asterisk using ARI into net.core 2.2 app. After installing version 1.2.1 of AsterNET.ARI nuget package I get the following warning
warning NU1701: Package 'AsterNET.ARI 1.2.1' was restored using '.NETFramework,Version=v4.6.1, .NETFramework,Version=v4.6.2, .NETFramework,Version=v4.7, .NETFramework,Version=v4.7.1, .NETFramework,Version=v4.7.2, .NETFramework,Version=v4.8' instead of the project target framework '.NETCoreApp,Version=v2.2'. This package may not be fully compatible with your project

There is a version of the nuget package with netstandard support in the source code, But I guess it's not published?
Can you publish the version with netstandard support? Probably, It would be useful not only for me. Please, tell if any help needed.

I downloaded your example(AsterNET.ARI.SimpleTestApplicationAsync)
Run it and click "#" , the phrase is not pronounced, and immediately goes off.
Log from asterisk:

But
case "*":
await sender.Channels.PlayAsync(e.Channel.Id, "sound:asterisk-friend");
await sender.Channels.PlayAsync(e.Channel.Id, "sound:goodbye");

work fine.

I have created a extension at extension config for agi :
exten => 200,1,agi(agi://" + DEV_HOST + @"/customivr.agi)
exten => 200,2,Hangup()
I have created a script in agi bin by placing customerivr class code . But it is forwading the call to 200 and showing Agi status Successful but not playing any stream file .It is showing the events of AMI. Please reply me quick i few days left to complete my Final year project.

Regenerating the code for the ARI Events and Actions does not work out of the box. Here are some issues I had:

• at https://github.com/skrusty/AsterNET.ARI/blob/master/CodeGeneratror/ARICodeGen/Templates/Models.tt#L23 there is an absolute file path that points to the json definition files. I think this should be changed to @"..\Data"
• When I run the code generator inside Visual Studio 2015, I get some excessive newlines, for example between every param line.

I needed to change:

#>
        /// <param name="<#= param.SelectToken("name").Value<string>() #>"><#= param.SelectToken("description").Value<string>() #></param>
<#

into

#>      /// <param name="<#= param.SelectToken("name").Value<string>() #>"><#= param.SelectToken("description").Value<string>() #></param>
<#

to avoid two newlines (one before the param line, and the one after).

• I think that the date in the header comment should be removed as long the code files are checked in to the repository, so that merge conflicts can be avoided.
• In VS2015, the files are generated in a subdirectory Templates. It is not clear how these files should be distributed / copied back into the Asternet.ARI project in the directory structure below ARI_1_0. A script would be nice, or some kind of post build process in the code generation step.
• The generated code uses tabs, but the rest of the code uses spaces.

The following lines:

https://github.com/skrusty/AsterNET.ARI/blob/master/AsterNET.ARI/ARI_1_0/Actions/IEndpointsActions.cs#L25

https://github.com/skrusty/AsterNET.ARI/blob/master/AsterNET.ARI/ARI_1_0/Actions/IEndpointsActions.cs#L44

https://github.com/skrusty/AsterNET.ARI/blob/master/AsterNET.ARI/ARI_1_0/Actions/EndpointsActions.cs#L46

https://github.com/skrusty/AsterNET.ARI/blob/master/AsterNET.ARI/ARI_1_0/Actions/EndpointsActions.cs#L135

do not look right. I think that there is a problem with the code generator.

I create Conference with SimpleConf demo. I can join to conference when I dial in. But how to dial out from running conference and add call to running conference?

I try to dial with ariClient.Channels.Originate(). My mobile rings and after I answer I'm not in the conference.

What I'm missing?

AsterNET.ARI uses WebSocket4Net 0.8, which contains a bug that prevents changing the state of the socket when the server drops the connection in an connection attempt. This could stall the connection process in AriClient (I could reproduce this problem with AsterNET.ARI before updating my fork):

kerryjiang/WebSocket4Net@3dddbb4

This problem has been fixed since the nuget package version 0.10.

Hi,

I am new to Asterisk and have written a sample in Asternet.ARI app. The app facilitates the dialing of 2 outbound calls and allows DTMF to play/stop MOH.

All the docs I have found indicate that I HAVE to have a simple Stasis dialplan, in order to do the above. E.g.

exten => 1001,1,NoOp()
same => n,Answer()
same => n,Stasis(StasisTest)
same => n,hangup()

However, I am able to enter Stasis WITHOUT the above dialplan existing. I've pasted the pertinent portion of the code I'm using below.

static void Main()
{
    AriClient ActionClient = new AriClient(new StasisEndpoint("<IP>, 8088, "<username>", "<password>"), StasisTest);

    ActionClient.OnStasisStartEvent += c_OnStasisStartEvent;
    ActionClient.OnStasisEndEvent += c_OnStasisEndEvent;
    ActionClient.OnChannelDtmfReceivedEvent += ActionClientOnChannelDtmfReceivedEvent;

    ActionClient.Connect();
    Bridge SimpleBridge = ActionClient.Bridges.Create("mixing", Guid.NewGuid().ToString(), AppName); 

    ActionClient.Applications.Subscribe(AppName, "bridge:" + SimpleBridge.Id);
    Channel ch1 = ActionClient.Channels.Originate(strEndPoint1, null, null, null, null, "StasisTest");
    Channel ch2 = ActionClient.Channels.Originate(strEndPoint2, null, null, null, null, "StasisTest");
}
 static void c_OnStasisStartEvent(object sender, AsterNET.ARI.Models.StasisStartEvent e)
{
            // Answer channel
            ActionClient.Channels.Answer(e.Channel.Id);
        
            // Add channel to bridge
            ActionClient.Bridges.AddChannel(SimpleBridge.Id, e.Channel.Id, "participant");
}

I am trying to understand why one would require the Dialplan when I'm able to enter into Stasis without using a Dialplan. As I've explained, I'm a novice Asterisk user, so it's possible I'm overlooking some fundamental point.

Any info will be much appreciated.
Thank you

I created a new .NET console project. When I installed AsterNET.ARI from Nuget and tried to run the bridge sample, I got a runtime exception on ActionClient.Connect();.

Method not found: 'Void WebSocket4Net.WebSocket..ctor(System.String, System.String, System.Collections.Generic.List`1<System.Collections.Generic.KeyValuePair`2<System.String,System.String>>, System.Collections.Generic.List`1<System.Collections.Generic.KeyValuePair`2<System.String,System.String>>, System.String, System.String, WebSocket4Net.WebSocketVersion, System.Net.EndPoint)'.

What can be the problem? I tried this with a .NET 4.5 console project, AsterNET.ARI is the latest (1.2).

SimpleConf project RemoveUser method throws exception
"System.Net.Http.HttpRequestException: Response status code does not indicate success: 400 (Bad Request)."
when executing _client.Bridges.RemoveChannel(Confbridge.Id, channelId);

I really new to programming, sorry for silly question.

The description say that the package supports cross-platform development with Mono.

However, when I try to use it in my Xamarin Forms project, I get the following compiling errors.

Thank you for help

I am trying to create an ARI based app using .net Core 2.1and asterisk 15 on an ubuntu 18.04 box.
I am connecting using the loopback interface with the following code:
Console.WriteLine("Creating connection:");
StasisEndpoint ARIStasisEP = new StasisEndpoint("127.0.0.1", 8088, "CareHawk", "chNTM");
Console.WriteLine(ARIStasisEP.AriEndPoint);
ActionClient = new AriClient(ARIStasisEP, "CareHawkNTM");

            // Hook into required events
            ActionClient.OnStasisStartEvent += NewPhoneConnected;
            ActionClient.OnStasisEndEvent += PhoneHangup;
            ActionClient.OnChannelDtmfReceivedEvent += DTMFReceived;
            ActionClient.OnConnectionStateChanged += StateChanged;
            Console.WriteLine("Succesfully created ARI.");

            ActionClient.Connect();
            Console.WriteLine("Connect to ARI attempt started.");

Occasionally I get the StateChanged function showing the state has changed to true and everything works fine.

But many more times I get no response after the ActionClient.Connect() and nothing shows in the asterisk about my ari app being connected.

I have other ARI apps written in node.js that work fine with same versions of Linux(Ubuntu) and Asterisk.

Any idea what I might be doing wrong?

Hi there,

I was wondering why did you encapsulate the websocket connection states and why did you expose only two of them (Open and Closed) ? This can lead to some problems if someone wants to force socket's reconnection.

For example: if I want to use the autoreconnect feature and also to expose to the end user the possibility to manually reconnect the socket, then you can have an inconsintent state. If the state of the websocket is Connecting and the user tries to manually reconnect it, it will raise a WebSocket exception. ("The socket is connecting, cannot connect again!").

Thanks,
Claudiu

Hi guys,

Asternet ARI downloaded via Nuget contains a wrong dll reference (1.1.0 instead of 1.2.0) for .Net45.
So, when I try to connect there is an exception (WebSocket4Net constructor - missing method)

Hi,

i tried to send fax using AsterNET.ARI without any success.
Can we SendFax using AsterNET.ARI?
if yes how we do it?

Try to use your code from repository. At example Sync method return error:

RunSynchronously may not be called on a task not bound to a delegate, such as the task returned from an asynchronous method.

If change code:

 public IRestCommandResult<T> ProcessRestCommand<T>(IRestCommand command) where T : new()
        {
            var cmd = (Command) command;
            var result = cmd.Client.Execute<T>(cmd.Request);
            result.RunSynchronously();

            var rtn = new CommandResult<T> {StatusCode = result.Result.StatusCode, Data = result.Result.Data};

            return rtn;
        }

        public IRestCommandResult ProcessRestCommand(IRestCommand command)
        {
            var cmd = (Command) command;
            var result = cmd.Client.Execute(cmd.Request);
            result.RunSynchronously();

            var rtn = new CommandResult {StatusCode = result.Result.StatusCode, RawData = result.Result.RawBytes};

            return rtn;
        }

To

public IRestCommandResult<T> ProcessRestCommand<T>(IRestCommand command) where T : new()
       {
           var cmd = (Command) command;
           var result = cmd.Client.Execute<T>(cmd.Request);
           result.Wait(new TimeSpan(0, 0, 0, 10));

           var rtn = new CommandResult<T> {StatusCode = result.Result.StatusCode, Data = result.Result.Data};

           return rtn;
       }

       public IRestCommandResult ProcessRestCommand(IRestCommand command)
       {
           var cmd = (Command) command;
           var result = cmd.Client.Execute(cmd.Request);
           result.Wait(new TimeSpan(0, 0, 0, 10));

           var rtn = new CommandResult {StatusCode = result.Result.StatusCode, RawData = result.Result.RawBytes};

           return rtn;
       }

start working normaly

When i try to put in a channel variable it doesnt seem to make it to asterisk.

List<KeyValuePair<string,string>> bridgeID = new List<KeyValuePair<string,string>>(){
                    new KeyValuePair<string, string>("BRIDGEID", BRIDGEID)};

                    foreach(var element in bridgeID)
                    {
                        Console.WriteLine(element);
                    }

                    roboClient.Channels.Originate("SIP/200", "2011", "from-internal-custom", 6, null, null, null, null, bridgeID, newid, null);

I need to have a click to dial in our Net Core app, I tried below:

var _leg1 = _ari.Channels.Originate("PJSIP/1234", "908171234566", "from-internal", 1, null, "AppDial", null, "1234", 30, null, null, null, null);

Bridge _br = await _ari.Bridges.CreateAsync();
await _ari.Bridges.AddChannelAsync(_br.Id, _leg1.Id, "member");

it calls 1234 but it does not call 908171234566

please help

Hi,

In my app a user can set up a conference by completing a form in the web app UI which inserts the conference details into the local DB, like auto-incremented integers as conference Id's, callerId, Pin, startTime etc...

The SimpleConf Conference constructor has a Guid Id parameter that is generated on the spot each time a bridge is created?

My question is how can I link my set conference to the Stasis conference and add a caller into the correct conference in case of multiple conferences in the same time?

Thanks.
Dan

I create Conference with SimpleConf demo. I can join to conference when I dial in. But how to dial out from running conference and add call to running conference?

I try to dial with ariClient.Channels.Originate(). My mobile rings and after I answer I'm not in the conference.

What I'm missing?

Hi Ben,

As I said in my email, I'm trying to create a conference app using your AsterNet.ARI project, but I have some unclarities/difficulties.
We have an external Asterisk server upgraded to version 13 to support the RESTful interface.
I've put the server/conference details into the app and it successfully connects: "Connection state is now true".

Q: It's not clear for me how can I create a dialplan application and test the app by dialing a number from my phone and receiving some kind of response, using AsterNet.ARI?

Thanks
Dan

What am I missing here? Application always says -- Channel Not In Stasis Application

Here are the basics in my test:

DialerClient = new AriClient(new StasisEndpoint(endpoint, Convert.ToInt32(port), username, password), application);
DialerClient.Connect();
DialerClient.OnConnectionStateChanged += OnStateEvent;
DialerClient.OnStasisStartEvent += OnStartEvent;
DialerClient.OnStasisEndEvent += OnEndEvent;

** Events not shows

This is where it breaks:

var x = DialerClient.Channels.Originate("SIP/[email protected]", extension: "1000", app: application);
GlobalDialer.DialerClient.Channels.Ring(x.Id); -- Breaks here / With any event really

The channel is created, but when I look at the channel ids in the DialerClient there are none.
I thought that this was supposed to create the channel an register it in Stasis.
It never shows in Stasis. What could be going wrong?
What do I need to do to get the channel in the Stasis application?
Is the dial plan absolutely required?
If not can someone give me some example code for how it could be accomplished?

Thanks

Chris

I'm doing an application that shows a call list, I'm using "OnStasisStartEvent" and "OnStasisEndEvent", but it doesn't work. What else do I need to do?

hi
I want to use External Media as described in https://wiki.asterisk.org/wiki/display/AST/External+Media+and+ARI
I am coding in C# and would like to know if this API supports that functionality or if there are any, out there, that does?

I'm trying to spy on a channel, but when executes this line:
ARICliente.Channels.SnoopChannel(channelId, AppName, "both");
it throws an exception saying;

Unable to find the requested value 'QueryString'.

How do I solve that problem?

Hi there,

It would be useful if the framework will return the HTTP status code after you execute a HTTP request.

For example EventsActions::UserEvent method should return the IRestCommandResult from the execute method (or raise an exception).

Cheers,
Claudiu

Hi, I noticed that even though the events received from Asterisk do have an ordering guarantee (it's a concern in their design, for example see the fixed bugs here and here), the ordering is not guaranteed in the AriClient, because it dispatches the received events to the thread pool with Delegate.BeginInvoke().

One example is that a hangup event always must come before the stasis end event, and I can imagine other related issues, like the playback started and finished event, though I do not have much experience with ARI so far.

The WebSocket implementation does seem to guarantee the ordering, because there is always the .NET socket's IOCompletionCallback on the stack that is delivering the socket's data.

I don't see an elegant solution to this problem based on the current event handler based design of the AriClient. The only solution I can think of would be to provide a SynchronizationContext of a dedicated thread to dispatch the events to.

One alternative I can think of would require the following changes:

• AriClient only maintains one properly ordered queue of events, probably including the connection state events.
• Events can be dynamically dispatched to an object that implements interfaces of the particular method groups (channel, bridge, etc.). This way, clients can use the current thread or power up their own, then pull out one event after another from AriClient and dispatch the events to their object that implements their state machine.

Logic:

if ((int)response.StatusCode >= 200 && (int)response.StatusCode < 300)
                return;
            switch ((int)response.StatusCode)
            {
                case 400:
                    throw new AriException("Invalid reason for hangup provided", (int)response.StatusCode);
                case 404:
                    throw new AriException("Channel not found", (int)response.StatusCode);
                default:
                    // Unknown server response
                    throw new AriException(string.Format("Unknown response code {0} from ARI.", response.StatusCode), (int)response.StatusCode);
            }

and some similar code doesn't work it just throw exception if StatusCode not ok

Is it possible to get instructions for SimpleConfAsync?
Simple 'How-To-Use' instructions.

Thanks in advance.

Centos 7
asterisk 16

I want use GetObject,UpdateObject to get /add a pjsip.but it's bad request
exp in Centos I use
$ curl -X PUT -H "Content-Type: application/json" -u asterisk:secret -d '{"fields": [ { "attribute": "auth_type", "value": "userpass"}, {"attribute": "username", "value": "alice"}, {"attribute": "password", "value": "secret" } ] }' https://localhost:8088/ari/asterisk/config/dynamic/res_pjsip/auth/alice

can add an auth,
but in asterNET.ARI, I like this to do ,but it's 400 (Bad request)

           ActionClient = new AriClient(new StasisEndpoint("192.168.137.211", 8088, "asterisk_ari", "123456"), AppName);

            var authDic = new Dictionary<string, string>();
              
            authDic.Add("auth_type", "userpass");
            authDic.Add("username", "alice");
            authDic.Add("password", "secret");
             ActionClient.Asterisk.UpdateObject("res_pjsip", "auth", "alice", authDic);

when alice is create by other way,it's sucess,but alice is not create ,it's return bad request

hope any help,tks

I'm trying to push notifications to clients who have connected to SignalR Hub based on related events are happening in PBX VOIP server.

I can get events using DeviceStateChangedEvent class from AsterNet using an event handler and want to push notification to clients related to their devices' state changes.

Also, SignalR connection is working as well and welcome message is showing on client web page.

But the problem is while sending notification by SendAsync method to caller client, my Hub goes to be disposed and below exception raised:

System.ObjectDisposedException: 'Cannot access a disposed object.
Object name: 'AgentHub'.'

Here is my Hub class.

using Microsoft.AspNetCore.SignalR;
using System;
using System.Threading.Tasks;
using AutoDialFinal.Models;
using AsterNET.ARI;
using AsterNET.ARI.Models;

namespace AutoDial.Hubs
{
    public class AgentHub : Hub
    {
        public AgentHub()
        {
            AriClient ActionClient;

            ActionClient = new AriClient(
                new StasisEndpoint("voip", 8088, "root", "password"),
                    "HelloWorld",
                    true);

            ActionClient.OnDeviceStateChangedEvent += ActionClientDeviceStateChangeEventAsync;

            ActionClient.Connect();

            void ActionClientDeviceStateChangeEventAsync(IAriClient sender, DeviceStateChangedEvent e)
            {
                var notification = new DeviceStateChangeNotification
                {
                    NotificationText = e.Device_state.Name + "'s state changed to " + e.Device_state.State,
                    SentAt = DateTime.Now.ToString()
                };

                SendNotificationToAgentAsync(notification);

            }
        }


        public override async Task OnConnectedAsync()
        {
            var notification = new DeviceStateChangeNotification
            {
                NotificationText = "Welcome!",
                SentAt = DateTime.Now.ToString()
            };

            await Clients.Caller.SendAsync(
                "ReceiveNotification",
                notification.NotificationText,
                notification.SentAt
            );

            await base.OnConnectedAsync();

        }

        public void SendNotificationToAgentAsync(DeviceStateChangeNotification notif)
        {
            Clients.Caller.SendAsync(
                "ReceiveNotification",
                notif.NotificationText,
                notif.SentAt
            );
        }
    }
}

Exception will raise in below method in ARIClient class while any device state change happening in PBX:

    private void _eventProducer_OnMessageReceived(object sender, MessageEventArgs e)
    {
        Debug.WriteLine(e.Message);
        // load the message
        var jsonMsg = (JObject)JToken.Parse(e.Message);
        var eventName = jsonMsg.SelectToken("type").Value<string>();
        var type = Type.GetType("AsterNET.ARI.Models." + eventName + "Event");
        var evnt =
            (type != null)
                ? (Event)JsonConvert.DeserializeObject(e.Message, type)
                : (Event)JsonConvert.DeserializeObject(e.Message, typeof(Event));

        lock (_syncRoot)
        {
            if (_dispatcher == null)
                return;

            _dispatcher.QueueAction(() =>
            {
                try
                {
                    FireEvent(evnt.Type, evnt, this);
                }
                catch(Exception ex)
                {

                    **// HERE IS WERE EXCEPTION IS RAISING**

                    // Handle any exceptions that were thrown by the invoked event handler
                    if (!UnhandledException(this, ex))
                    {
                        Console.WriteLine("The event listener " + evnt.Type.ToString() + " cause an exeption: " + ex.Message);
                    }
                }
            });
        }
    }

How do I fix this problem?
Thank you

Hi,

I need to know if there's a way to pass data from an external Stasis app to a Dialplan. I'm using ...channel//continue

Scenario:

• call from outside world is directed to an extension and dialplan in Asterisk
• Dialplan Answers and places the channel into an external stasisapp
• Stasis app performs some functionality then sends the channel back to dialplan
  (...channel//continue)

exten => 1001,1,NoOp(entering ${CONTEXT} as defined in extensions_custom.conf) same => n,Answer() same => n,Stasis(ZIN1,arg1) same => n,Hangup()

The data I wish to pass the dialplan could be char or numeric.

Thank you

Hi,

The links in the section is failed.

I have an application with 5 threads, Each thread establishes an connection to Asterisk with the same Stasis App Name. I assumed that each connection creates an "instance" of the stasis app name. However, only the 1 thread gets messages from Channels that have been placed in that app.

I've checked the Asterisk logging, and it appears as if the Stasis App gets overwritten each time, as it's sharing the name of an existing app.

If possible, could someone elaborate on why this happens? I would have expected all the threads subscribing to the same app name to get duplicate events.

Please advise if you require any further info.

Thank you
Sue

how can i edit conf file with asternet.ari ?

ex;
sip.conf
extensions.conf

I couldn't see it in the documentation.

Error Message "Could not load file or assembly 'WebSocket4Net, Version=0.14.1.0, Culture=neutral, PublicKeyToken=eb4e154b696bf72a' or one of its dependencies. The system cannot find the file specified"

Creating projects running on .NET core work perfectly, but to use speech synthesis I need to target the full .NET platform, as the speech synthesis assemblies are not yet available on core.

I've gone back in full .NET versions as far as I can without all the dependencies AsterNET uses, falling apart and the earliest version test is .NET v4.5.1

I have tested all the way up to v4.7.2 using both Visual Studio 2017 and Visual Studio 2019 (Release and Preview Builds) running as Admin and not as Admin.

In all cases, everything builds and references fine, but as soon as you try to run the app the following exception is thrown.

For reference, I've also performed recommended NuGet updates (Taking Websocket up to 0.15.12) and as well as reinstalling against different versions, have also test built from scratch.

Output seen in image is 100% consistent every time, have tested this on 2 different asterisk servers and same result.

Hi, This is more a request than an issue. I am new to asterisk and ari, I managed to get the examples up and runnning on a freepbx installation but I'm battling with making and outbound call "Originate".

Can you assist me with a simple example of dialing an internal extension from an internal extension using asternet.ari? I want to use this as a click to dial function not neccessarily from within a bridge.

Also, is asternet.ari recommended for outbound dialing or should I rather consider AMI for dialing?

Any help will be much appreciated.

Thanks,

Hi,
Can more than 1 stasis app listen in on a Channel?
E.g. I have 2 stasis apps, and both must get a stasisStart event when the Channel is answered.

Thank you

I need to register my extensions to the asterisk using Asternet.ARI (like other softphone), then set events such as receiving call, registration for having conversation between clients connected to the asterisk(using Asternet).
dose Asternet.Ari support my need without using a third party softphone application like X-Lite?
I'm trying to implement Asternet to ASP Core web app and not willing to use libraries such as Sip.js...

I recently re-installed Asterisk so I had to create a new ari user.

When trying to use this package to create a call it got stuck when creating a bridge and no error was thrown.

I later found wat was wrong, I forgot to set the read_only variable in my ari user to no.
I found this when testing ari with curl:

>curl -v -u username:password -X POST http://192.168.2.22:8088/ari/bridges
*   Trying 192.168.2.22...
* TCP_NODELAY set

Could this package maybe throw an error when you are in read_oly mode and you are trying to update/create?
Thank you in advance.
