Providing a private connection for a mobile device in a wireless local area network includes a mobile device operable to associate to a home wireless local area network (WLAN), request a temporary digital extension from the WLAN, receive an assigned temporary digital extension from the WLAN, register with the WLAN using the temporary digital extension, and initiate a call from the temporary digital extension to a target extension. In addition, an in-store server is operable to register the temporary digital extension, recognize the temporary digital extension in the initiated call, establish the call to the target extension, and route the call between the temporary digital extension and the target extension.
