RBX +Plus (Radio Branch Exchange) is an advanced telephone interconnect specifically designed to allow radio users to make and receive phone calls directly on their MOTOTRBO radios. 

RBX +Plus brings all the benefits and functionalities of corporate unified communications to digital radios, enabling industries to operate under one private business critical mobile telephony network. This product allows digital radios to communicate with phones with access to familiar telephony features, such as call history, phonebook, and caller ID. It gives customers the ability to truly control their mobile communications coverage area while reducing mobile communications costs without sacrificing functionality. RBX +Plus streamlines communication between phone and radio users with private calls, talkgroups and callgroups. The app was designed to easily scale, and can connect digital two-way radios to something as simple as a standard POTS phone line or as complex as a corporate phone system (PBXs).

This application provides organisations with a compelling alternative to cellular and WiFi solutions for their mobile work force. While staying connected in any location is paramount, Zonith delivers the same cellular functionality directly to the mobile worker’s radio leveraging existing radio and telephony infrastructure in a whole new way.
