A mobile switching center receives a call to a wireless telephone unit and determines if the wireless telephone unit is available to receive calls. If the wireless unit is unavailable, the mobile switching center forwards the call to a wireless service node, preferably immediately and without providing any ring back tone to the calling party. The wireless service node prompts the calling party to speak a message for transmission to the wireless telephone unit. The wireless service node converts the message spoken by the calling party from a speech message to a text message and forwards text message to a short message service center for transmission to the wireless unit.
