neventsocket's Issues

does support Freeswitch 1.10.6 ?

some code like these :
using (var socket = await InboundSocket.Connect("192.168.1.100", 8021, "123456789"))
{

                //Tell FreeSwitch which events we are interested in
              //  await socket.SubscribeEvents(EventName.All);
                 await socket.SubscribeEvents(EventName.ChannelAnswer,EventName.ChannelCreate);
                //Handle events as they come in using Rx
                socket.ChannelEvents.Where(x => (x.EventName == EventName.ChannelAnswer
                || x.EventName == EventName.ChannelCreate
                    || x.EventName == EventName.ChannelHangup
                       || x.EventName == EventName.ChannelHangupComplete
                || EventName.ChannelOriginate == x.EventName
                || x.EventName == EventName.ChannelDestroy))
                          .Subscribe(async x =>
                      {
                          Console.WriteLine("Channel Answer Event " + x.UUID);

                          //we have a channel id, now we can control it
                          await socket.Play(x.UUID, "misc/8000/misc-freeswitch_is_state_of_the_art.wav");
                      });

                var apiResponse = await socket.SendApi("status");
                Console.WriteLine(apiResponse.BodyText);
                Console.WriteLine((await socket.SendApi("status")).BodyText);
                Console.WriteLine();
                Console.WriteLine((await socket.SendApi("invalid_api_command")).BodyText);
                Console.WriteLine();
                Console.WriteLine((await socket.SendApi("sofia status")).BodyText);
                Console.WriteLine();
                Console.WriteLine((await socket.SendApi("show bridged_calls")).BodyText);

                Console.WriteLine("Press [Enter] to exit.");
                Console.ReadLine();
            }

SendApi(...) looks ok . but xxxxx. .Subscribe(async x =>..... nothing happen at all when i use microsip for some dials .
i need some help for my question . please.. .

ChannelData.UUID from InboundSocket.Originate returns null

I was following the Demo https://github.com/iamkinetic/NEventSocket/blob/master/NEventSocket.Examples/Examples/DtmfExample.cs
But the program crashes since ChannelData.UUID is null.
I am using Freeswitch 1.10.6, with default configuration
For the softphones I used MicroSip and PhonerLite
the OS is Windows10

To Reproduce
Steps to reproduce the behavior:

Download Freeswitch,softphones and setup visual studio
Create new solution/project (and install NEventSocket using NuGet)
In Program.cs put this code:
`using Microsoft.Extensions.Logging;
using NEventSocket;
using NEventSocket.FreeSwitch;
using System;
using System.Collections.Generic;
using System.Reactive.Linq;
using System.Threading.Tasks;

namespace Test_FSw
{
class Program
{
static async Task Main(string[] args)
{
NEventSocket.Logging.Logger.Configure(new LoggerFactory());
InboundSocket client;
client = await InboundSocket.Connect("localhost", 8021, "ClueCon", TimeSpan.FromSeconds(20));

        var originate = await client.Originate("user/1001", new OriginateOptions
        {
            CallerIdNumber = "123456789",
            CallerIdName = "test2",
            HangupAfterBridge = false,
            TimeoutSeconds = 20
        });

        if (!originate.Success)
        {
            Console.WriteLine("Failed");
            Console.WriteLine(originate.HangupCause.ToString());
            await client.Exit();
        }
        else
        {
            Console.WriteLine(originate.ChannelData.UUID);/*UUID or ChannelData is null*/
            var uuid = originate.ChannelData.UUID;
            /*unreached code*/
            await client.SubscribeEvents(EventName.Dtmf);
        }
        Console.WriteLine("Exit[Enter]");
        Console.ReadLine();


    }
   
}

}

`
4. Execute

Value cannot be null. (Parameter 'factory')

I created a simple program and got Value cannot be null. (Parameter 'factory') from Microsoft.Extensions.Logging.Abstractions

code as follows :

using System;
using System.Reactive.Linq;
using System.Threading.Tasks;
using NEventSocket;
using NEventSocket.FreeSwitch;

namespace ConsoleApp1
{
class Program
{
static async Task Main(string[] args)
{
await CallTracking();

        Console.WriteLine("Hello World!");
    }

    public static async Task CallTracking()
    {
        using (var socket = await InboundSocket.Connect("XXX.XXX.XXX.XXX", 8021, "ClueCon"))
        {
            var apiResponse = await socket.SendApi("status");
            Console.WriteLine(apiResponse.BodyText);

            //Tell FreeSwitch which events we are interested in
            await socket.SubscribeEvents(EventName.ChannelAnswer);

            //Handle events as they come in using Rx
            socket.ChannelEvents.Where(x => x.EventName == EventName.ChannelAnswer)
                  .Subscribe(async x =>
                  {
                      Console.WriteLine("Channel Answer Event " + x.UUID);

                      //we have a channel id, now we can control it
                      await socket.Play(x.UUID, "misc/8000/misc-freeswitch_is_state_of_the_art.wav");
                  });
        }
    }
}

}

any ideas ??

i am using .net core 3.1

Update documentation

Is your feature request related to a problem? Please describe.
The documentation is not up to date. Some work needs to be done.

I don't understand how to use it

For beginners, I don't need to care about NEventSocket.Tests. I just need to introduce the NEventSocket class library in my own project, and call InboundSocket.cs and OutboundListener.cs during project execution. Can I just listen? Is there a demo that can be run directly.

Examples are not compatible with Net Core 3.x

Solution builds ok on Net Core 2.x. But when changing to Net Core 3.0, example project doesn't build. Get a lot of errors like:
'ILifetimeScope' does not contain a definition for 'ImplementationsFor' and no accessible extension method 'ImplementationsFor' accepting a first argument of type 'ILifetimeScope' could be found

Guess some extensions are missing in Net Core 3.x.

Any ideas?

Best regards, Gregor

Support Voicemail natively

ITNOA

Is your feature request related to a problem? Please describe.
This feature request is aimed at accessing the events published by freeswitch regarding it's VoiceMail functionality.

Describe the solution you'd like
Natively supporting Event Headers and Messages in a structured way pertaining to Voice mail module of freeswitch.

Describe alternatives you've considered
while these events can be manually parsed as any other custom event at a higher layer, It is preferable to Implement the parsing of these events data alongside other custom events to prevent code duplication and move logic closer to data.

SubscribeEvents may not be Thread-Safe

I was using InboundSocket to originate some calls and play Audio files, and sometimes i got an ThrowInvalidOperationException_ConcurrentOperationsNotSupported where I called Play(...).

Here is the call stack:

    System.ThrowHelper.ThrowInvalidOperationException_ConcurrentOperationsNotSupported()
    System.Collections.Generic.HashSet<T>.FindItemIndex(T)
    System.Collections.Generic.HashSet<T>.Contains(T)
    NEventSocket.Sockets.EventSocket.SubscribeEvents.AnonymousMethod__28_0(NEventSocket.FreeSwitch.EventName)
    System.Linq.Enumerable.All<TSource>(System.Collections.Generic.IEnumerable<TSource>, System.Func<TSource, bool>)
    NEventSocket.Sockets.EventSocket.SubscribeEvents(NEventSocket.FreeSwitch.EventName[])
    NEventSocket.Sockets.EventSocket.ExecuteApplication(string, string, string, bool, bool, int)
    NEventSocket.ApplicationExtensions.Play(NEventSocket.Sockets.EventSocket, string, string, NEventSocket.FreeSwitch.PlayOptions)

I checked the library and I noticed the use of HashSet:
private readonly HashSet<EventName> subscribedEvents = new HashSet<EventName>();

Am I missing something or is it really not Thread-Safe ?

Release version 1.0 non beta.

Let's release version 1.0.

Is this library alive?
