Callback sample code block in C#

[jafarulla15]

Hello, I am new in ice and mumble.

Can you give me a sample code for callback. I don't found any example in C#.
It will be a very helpful for me and will save my time, as I already spend 3/4 days after it and don't found any solution in C#.

Best Regards

var callbackAddress = "127.0.0.1"; // must be 127.0.0.1

#region ADAPTER INSTANCE
// a) use adapter
//var version = "1.2.4";
//instance = new MurmurAdapter.Adapter(version).Instance;
#endregion
#region DIRECT INSTANCE
// b) or use direct connection to specified version
instance = new Murmur.Instance();

// callbacks for the instance (events for stop/start virtual servers)
var icb = new InstanceCallbackHandler();
icb_id = instance.AddCallback(icb);


// select virtual server by id

// callbacks for a virtual server

// remove any callback if needed

Thanks a lot for so quick response. I have tried your code and I think it's correct.
But I don't get any response fire.
I don't know, is there anything I need to enable at mumble server to get callback functional.
I am sorry to say, but can you please take a kind look at my implementation. Here is a console C# project.

Many many thanks

I got the issue. It's a networking issue. Mumble at aws server can't find my local ice client pc.

It's working fine when mumble server and ice client in the same network (ip of same series) and I am giving callbackAddress = my local pc IP and mumble server also in my local network, then it's working fine.

But is there any way to use the mumbler server in real IP and ice client local IP.
What is the configuration I need to edit, please?

Thanks

If PublishedEndpoints used for Murmur then callback address may be different from localhost. You should try it, I didn't test such case.
