Using Skype API to make call

问题

I am trying to making call programmatically through Skype. Skype is installed in my PC but when I am trying to make call through Skype API & C# then every time I am getting a exception called Connection refuse and I am not being able to fix it. So, looking for proper guide to solve the issue.

Here is code snippet by which I am trying to make call programmatically.

Skype skype;
skype = new SKYPE4COMLib.Skype();
string SkypeID = "+222222222";
Call call = skype.PlaceCall(SkypeID);
do
{
    System.Threading.Thread.Sleep(1);
} while (call.Status != TCallStatus.clsInProgress);

Please guide me what is missing in my code. Thanks
