TAPI no incoming “signals”? How to check the TAPI Driver?

Question

I try to learn and understand TAPI and I have tried A LOT of examples, all of them get my TAPI Line and I can dial out, but no event is fired when I have an incoming call, so I'm starting to think that the TAPI driver is not working properly/blocked by firewall/something completely different.

Last code I tried is http://pastebin.com/T3ZHkLi0 and I'm getting to MsgBox("We are here") end then it exits. Before that it fires the only TAPI line I have.

Is there any way to check why no incoming events are fired?

Specs

• Auerswald TAPI Driver: Specs
• MAYBE I have an estos TAPI driver running, how could I check that?
• ProCall on the Client Computer (interferes possibly?)
• Win10 64 bit

Any hint is highly appreciated

I suggest you to not use TAPI COM solution and use Julmar .Net 32-bit and 64-bit compatible solution http://atapi.codeplex.com/ . It's wrapper for TAPI.dll and easy to implement. You can simply convert this c# code into VB

TapiManager tapiManager = new TapiManager("TapiCallMonitor.net");
if (tapiManager.Initialize() == false)
        {
            MessageBox.Show("No Tapi devices found.");
            this.Close();
            return;
        }
foreach (TapiLine line in tapiManager.Lines)
        {
            try 
            {
                line.NewCall += OnNewCall;
                line.CallStateChanged += OnCallStateChanged;
                line.CallInfoChanged += OnCallInfoChanged;
                line.Monitor();
            }
            catch (TapiException ex)
            {
                LogError(ex.Message);
            }
        }
