A method of and system for processing calls to a wireless unit determines if the wireless unit is in a “page-only” mode or otherwise unavailable to receive the call. If said wireless unit is unavailable to receive the call, system determines if the calling party would like to send a page to the wireless unit. If so, the system sends a short message to the wireless unit. The short message identifies the calling party and provides an option to receive the call. When the wireless unit receives the short message page, the called party can elect to receive the call by sending short message response to the system. When the system receives the short message response, the system completes the call to said wireless unit if the short message response indicates selection of the option to receive the call.
