Make & Receive Phone Calls Directly From Your Radio With Teldio’s RBX Application

Teldio’s RBX (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 it 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).

RBX Call Types

With RBX you are able to make different types of calls between phones, radios, and more.

Private Calls

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




Phone users can reach groups of radios by allowing them to broadcast onto the radio network from anywhere. All radio users in the group 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 is entered into a private call with the phone user. Other users in the group are notified that the call has been answered.



How It Works

RBX +Plus is a software application installed on a server which connects two-way radios to the world of telephony.  The server interfaces to the radio system using MOTOTRBO™ control stations (mobile radios).  It was designed to connect to IP and analog corporate phone systems (PBXs), public telephone lines (PSTN lines), Internet Telephony Service Providers as well as GSM cellular networks.
