Is their any way Voice Recording and Uploading in server can be done via Web Application?
I'm using ASP.Net for my project.

My guess is may be via some ActiveX control....but I'm not sure how to do that.

If anybody has something, I would appreciate the help.

ActiveX didn't worked out for me.

But using open source Flash Media Server RED5 helped me solve this issue.
