Dialog PTT is an enterprise PTT over IP (PTToIP) platform for field teams, lone workers, and dispatch operations. End-to-end AES-256 encrypted. Works on Android, iOS, and Hytera radios. Live the same day.
Dialog PTT is a complete push-to-talk over cellular (PoC radio) platform — not just an app. Server, clients, dispatcher console, and hardware integration in a single product.
Instant push-to-talk over any cellular or Wi-Fi network. Sub-second audio delivery across unlimited range. No radio licence required.
See all features →Voice encrypted on the device before it leaves. The server relays ciphertext it cannot decrypt. Per-group keys, rotated automatically.
Security details →Real-time device positions on the dispatcher map. Geofencing alerts, location history, and GPS trail playback for incidents.
Dispatcher console →Timed check-ins, man-down (tilt/fall) detection, and SOS alarms. Alerts dispatchers instantly. Works on Hytera P60 ROM services.
Lone worker solution →Full-featured DialogDispatcher for Windows — live map, PTT from desk, stun/unstun devices, incident management, recording playback.
Dispatcher details →Deploy on your own VPS with Docker. Full data residency. 2 vCPU / 2 GB RAM is all you need. QUIC + WebSocket transport.
Self-hosted guide →Dialog PTT is one of the only PTToIP platforms with deep firmware-level integration for Hytera Android radios. The Hytera P50, P50E, P60, and MNC360 use Dialog PTT as their native PoC app — hardware PTT button, firmware display, GPS radio, and lone worker ROM all fully wired.
Instant PTT between field staff and a central dispatcher. Live map, private calls, group messaging, and incident management. Replaces DMR over cellular.
Dispatcher console →Timed check-ins, man-down detection, and SOS. If a worker doesn't check in, the dispatcher is alerted immediately. UK lone worker regulations compliant.
Lone worker solution →Encrypted PTT for security teams, venue events, and sensitive operations. AES-256-GCM means no RF interception risk. Works over LTE, no radio licence.
Security details →Yes — Dialog PTT is available as a fully managed hosted service. You are live the same day with no infrastructure to maintain. Self-hosted deployment on your own VPS is also available for organisations requiring on-premises data residency.
Dialog PTT works on any iPhone (iOS 15+), any Android smartphone (Android 8+), and Android-based PTT radios including Hytera P50, P50E, P60, MNC360, Inrico, Sonim, Blackview, and many others. No specialist hardware is required.
Yes. Dialog PTT uses AES-256-GCM end-to-end encryption. Voice is encrypted on the device before it reaches the server. The server relays ciphertext it cannot decrypt. Each talkgroup has its own key, rotated automatically.
Today Dialog PTT runs as a standalone IP PTT platform. DMR, TETRA, and Zello gateway interoperability are on the active development roadmap, allowing you to bridge Dialog PTT groups into existing radio infrastructure without replacing it.
Under an hour for a hosted deployment. We provision the server, you install the app and provision devices. For self-hosted, a single VPS with 2 vCPU and 2 GB RAM running Docker is all that is needed.
