How come when I make calls it says unknown name but it shows the number

Another thing, how can I make it so everyone that is in my business control panel can use the skype number I have?

I don't wanna buy a number for each employee I want each employee able to use the one number registered to the business cpanel

You can use PrettyMay Call Center for Skype to set up a outbound call center for your business, and all outbound calls go through the same SkypeID with the same outbound CallerID displayed.
