Respondr

Respondr PTT turns any smartphone, tablet or desktop into a secure, always-on two-way radio built for mission-critical teamwork. Tap once and talk live to a single colleague, a fleet or the whole organisation over Wi-Fi, LTE, 5G or even EDGE/2G. Our ultra-low-latency engine (<300 ms) keeps conversation natural while advanced voice compression slashes data use. Key benefits • Instant, encrypted voice — TLS transport plus optional AES-256 end-to-end encryption protect every word. • Works when coverage drops: messages queue offline and auto-deliver on reconnection. • Cross-platform — Android, iOS, Windows and rugged devices share the same channels. • Unlimited, dynamic talk-groups that dispatch or supervisors can create, rename and archive in seconds. • Location & playback: view live GPS, replay recent calls and search transcripts from the Respondr Dispatch console. • Accessory-friendly — wired headsets, shoulder mics, Bluetooth PTT buttons, vehicle mounts. • Scales instantly from a single site to global operations with no repeaters or base stations to buy.
