RBX +Plus – Two-way Radio Telephony

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. The application goes beyond basic telephone interconnects by allowing radio users to access familiar phone-like features, such as call history, phonebook, and caller ID. 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).

Private Calls

Radio users have the ability to place and receive private phone calls from their MOTOTRBO radio. This virtually transforms the two-way radio into a mobile phone.


Talkgroup extensions allow phone users to easily reach groups of radios. The phone user is virtually transformed into a radio allowing him to broadcast onto the radio network from any phone, anywhere. All radio users within the target talkgroup have the ability to hear the phone user and respond.


Callgroups allow phone users to ring a group of radios. The first person to answer within that ring group is entered into a private call with the phone user. Others users in the group are notified that the call has been answered.

Increased Productivity

By enabling MOTOTRBO radios to make and receive calls, mobile workers become increasingly productive as they no longer need to rely on multiple mobile devices to communicate.  No longer must they find a phone to make outside calls or carry both radio and cell phone. RBX +Plus also allows phone users to communicate seamlessly to a group of radios via talkgroups and callgroups.  This allows supervisors and managers to speak with their team members instantly, from virtually anywhere, at anytime.

Enhanced Worker Safety and Security

With RBX +Plus enabled on their MOTOTRBO radios, mobile workers are always connected. They are able to send and receive critical information without the need to communicate via a dispatcher. In the event of an emergency, a mobile worker can have access to dialing for help, whether it be internally to the security department or externally to a 9-1-1 operator. Emergency call boxes can also be linked to security callgroups and talkgroups to ensure immediate response and action.

Reduced Operational Costs

By coupling RBX +Plus with MOTOTRBO radios, you can extend the footprint of your corporate telephony system (PBX) to your radio network. This allows for a streamlined communication process and eliminates the need for disparate mobile communication infrastructure, such as cell phones, Nextel phone, and WiFi phones. Costly monthly operational costs are eliminated along with dead zones and weak signal strength, and replaced with a durable and robust private mobile communication network.
