Telephone interconnect & alert notifications

The features of a traditional analog phone patch and the benefits of both digital telephony and MOTOTRBO radios

Learn More


phone@trbo interfaces radios to public or corporate office phone systems. It offers the features of a traditional analog phone patch while adding the benefits of both digital telephony and MOTOTRBO radios.

Extensive voice prompts make it friendlier to use for telephone callers and subscribers and it boasts flexible configuration with several modes of operations.

phone@trbo can also be expanded to support email for alert notifications and work order management (tickets).

• Incoming emergency calls are immediately sent to the AllCall talkgroup without the need to answer them. Automatic outbound dialing on emergency notification from subscribers (including man-down).

• Text messaging include the caller-ID of an incoming call. In case the call is missed, it is easy to call back by simply replying to the caller-ID text message. Similarly, call filtering notifies phone callers that a radio is offline or they misdialed the group, thus freeing up airtime and the phone line.
