I guess that you mean like having a private line to your extension, I assume you have other lines that enable you to make local calls so what you have to do is to create a different incoming group id for these lines and also a different outgoing group id, then you have to create two different shortcodes, one for taking the local lines and the other to take the other ones. For example when you press '9' you'll get local tone, and when you press '0' you'll get the other tone. Also you can create an incoming call route directed to your extension when something comes from that lines. If you don't want the other users on the system to use the other lines then create the shortcode only in your user profile.
