A messaging system for determining whether a wireless message has been transmitted includes a wireless transmitter, a messaging controller and a transmission monitor. The transmission monitor receives all wireless messages transmitted by the transmitter and provides them to the messaging controller for comparison with message requests that were sent to the transmitter by the messaging controller. If a particular wireless message has not been received by the transmission monitor and fed back to the messaging controller within a predetermined amount of time, the messaging controller triggers at least one controlling action such as re-sending the message request to the transmitter, switching channels in the transmitter or notifying a system administrator.
