Hi Jeff,

Hello all. Still not able to figure out avmd in C# managed code. Please guide me.

1. My EventReceivedFunction takes only one argument (ev). There is a compile time error in visual studio if I pass (ev,s). My FreeSwitch.Managed.dll version is 1.0.5. Interesting thing is the intellisense does show as if EventReceivedFunction takes two arguments as you've shown. dtmf function works with two arguments.

2. Now, I look at examples on this page: http://wiki.freeswitch.org/wiki/Mod_avmd
What is C# managed equivalent? My code:
                mObjMainSession.Answer();
                mObjMainSession.Execute("avmd", "start");
                mObjMainSession.DtmfReceivedFunction = (d, t) =>
                {
                    Log.WriteLine(LogLevel.Notice, aObjCntx.Session.uuid + "-" + "Received {0} for {1}.", d, t);
                    return "";
                };

                if (check this is an outbound call)
                {
                    mObjMainSession.EventReceivedFunction = (ev) =>
                    {
                        Log.WriteLine(LogLevel.Notice, aObjCntx.Session.uuid + "-" + "Event type {0} / Event body {2} .", ev.GetEventType(), ev.GetBody());

                        if (mObjMainSession.GetVariable("avmd_detect") == "TRUE")
                        {
                            Log.WriteLine(LogLevel.Notice, aObjCntx.Session.uuid + "-" + "VM detected");
                        }
                        return "";
                    };
                }

If "VM detected", what do I do? Just call hang up from EventReceivedFunction?
Do I call "mObjMainSession.Execute("avmd", "stop");" anywhere?
Tutorial also says, one must wait a few seconds after answering the call before starting avmd. What does that mean?
How do I find out load on CPU being put by avmd? I will be making 50 concurrent outbound calls.

3. Same managed code on my extension handles inbound (uses calling system) as well as outbound calls (system calling users). Should I only enable/check avmd when it is an outbound call?

Please help.

Thanks.

Sure,

Modify this sample out of demo.csx from the source tree. maybe enough here
to get you started.

using System;
using FreeSWITCH;
using FreeSWITCH.Native;

public class AppDemo : IAppPlugin {

    ManagedSession Session;
    public void Run(AppContext context) {
        Session = context.Session;
        Session.Answer();
        Session.DtmfReceivedFunction = (d, t) => {
            Log.WriteLine(LogLevel.Notice, "Received {0} for {1}.", d, t);
            return "";
        };

        Session.EventReceivedFunction = (ev, s) => {
            return "";
        };

// add your stuff here

        Log.WriteLine(LogLevel.Notice, "AppDemo is finishing its run and
will now hang up.");
        Session.Hangup("USER_BUSY");
    }

}
