The dispatch console

And one console that hears everything.

Every channel, every network, every unit — dispatched from the browser, Windows desktop, or a standalone control-room console.

Built for dispatch

Everything a control room needs. Nothing it doesn’t.

Voice recorder

Every transmission, on the record.

Respondr records the traffic on every channel and keeps it in one searchable archive. Filter by date, channel or operator, replay the audio in the browser, and export what an audit asks for.

The push-to-talk app.

Turn any smartphone into a walkie-talkie: instant voice over Wi-Fi, LTE and 5G, with military-grade encryption and dedicated PTT accessories.

Editions

One platform, four ways to run it.

Respondr routes its own intercom audio and bridges the radio networks you already own. Every edition talks to the others — pick the one each team needs.

Respondr Mobile

iOS · Android · PoC
Field crews and vehicles. Push-to-talk over Wi-Fi, LTE and 5G, with BLE and HID accessories.

Respondr Dispatch

Web
The server is the console: it opens in any browser, on any operating system, with nothing to install.

Respondr Desktop

Windows
The same console outside the browser, with global keyboard shortcuts on an office PC.

Respondr Standalone

Windows · Linux · macOS
A self-contained control room. No server to run — FT636B and FT638 gateways connect directly.
Console series

Dispatch hardware built for the control room.

Three form factors running the same Respondr software: a hardened, fanless Linux build with programmable PTT keys, gooseneck microphone and speakers. It drops into a new desk or beside the radio system you already run.

Multi-network bridging

Your radios don’t change. Everything else does.

Radio gateways connect your existing DMR, TETRA and analog infrastructure to Respondr — no fleet replacement, no forklift upgrade.

Network patching

Join two networks with one click.

Patch an analog, DMR or TETRA channel to another — or to the Respondr intercom — and the two talk as one. A DMR patrol hears the TETRA crew directly, with no relay operator repeating traffic in the middle.

System architecture

Designed for redundancy, from the gateway up.

Respondr Core, radio gateways and clients form a single fault-tolerant chain — deployed in the AWS EU region, on-premise, or hybrid, with redundant server connections at every tier.
