Initially conceptualised by parent company Com2 Communications, a service was required to fulfil the need of providing awareness to local communities about newly available services in their area. Due to demand and the effectiveness of these two services, OnCall Messaging has developed into a stand-alone company providing community contact services and emergency notification systems to the consumer, business and government market.

With the support of a local and international carrier base, dedicated research and development staff, OnCall is proud to offer this unique and reliable Voice Broadcast technology across all Australian telephone networks.
