Dialog PTT is structured across two plans — Core and Professional. Features marked Pro+ require Professional. See pricing →
Instant push-to-talk over any cellular or Wi-Fi network. Sub-second audio delivery across unlimited range. No radio licence required.
Organise devices into named talkgroups. Switch groups from the app or dispatcher console. Simultaneous groups supported.
Broadcast a single announcement to every channel at once with one-touch All-Call — reach the whole fleet instantly, then hand the floor back to normal traffic.
One-to-one PTT calls between any two devices on the network. Initiated from the app or from the dispatcher console.
High-quality Opus audio at configurable bitrates. Optimised for voice intelligibility on low-bandwidth and high-latency connections.
On-device noise suppression powered by Silero. Filters wind, vehicle, and crowd noise before transmission — no server-side processing required.
Hands-free voice-activated transmission. Configurable threshold and hold time. Works alongside hardware PTT buttons.
Pair external Bluetooth Low Energy PTT buttons to the app — lapel, glove, steering-wheel, or handheld remotes. Push to talk without reaching for the device. Scan, pair, and bind in seconds; works alongside the on-screen and hardware PTT keys.
Text and image messaging within talkgroups. Messages stored server-side and delivered on reconnect — nothing missed when a device is offline.
End-to-end encrypted audio on every call. Per-group keys rotated automatically. The relay server cannot decrypt audio in transit. Security details →
Audio delivered over the fastest available encrypted connection — the same generation of transport technology powering modern web infrastructure. Automatic fallback keeps PTT working through strict firewalls and mobile APNs. Security details →
Switch a one-to-one call to full duplex — both parties speak at once, just like a phone call. No floor handover, no PTT button. Initiated from the app, the map, or the dispatcher console.
Field users send a "call me" request to the dispatcher at the press of a button — no need to tie up a talkgroup. The request pops up on the dispatcher console; one click opens a private call straight back to the device.
Wear OS app for Samsung Galaxy Watch and Pixel Watch. See the active channel and talker, push to talk, switch channels, and trigger SOS — all from the wrist, paired to the phone.
Incoming text messages and channel changes are read aloud on the device. Hands-free awareness for drivers and field crews who can't look at a screen.
Live video streaming from the field to the dispatcher, alongside PTT audio. Arriving in an upcoming release.
Timed check-in intervals configurable per device. If a worker misses a check-in, dispatchers are alerted immediately with device location. Full lone worker details →
Accelerometer-based detection of device orientation change consistent with a fall or incapacitation. Alert escalates to the dispatcher console with location.
Dedicated SOS button triggers an immediate alarm to all dispatchers. Works on Hytera P-series hardware buttons and the Android app emergency button.
SOS, man-down, and lone worker alarms appear instantly on the dispatcher map with pulsing indicators and audio alert. Alarm cancel available remotely.
Real-time device positions on the dispatcher map. Geofencing alerts, location history, and GPS trail playback for incidents.
Define zones on the map. Receive alerts when devices enter or leave a geofenced area. Configurable per-group from the dispatcher console.
Bluetooth beacon support locates devices inside buildings where GPS can't reach. Beacon zones appear as a live overlay on the dispatcher map and are managed from the web portal.
Field users set their status — Available, En-Route, On-Scene, Standby, Break, Busy, or Clear — straight from the app. The dispatcher sees every unit's current status update live on the console.
Build patrol routes from ordered checkpoints — NFC/Bluetooth beacons or GPS waypoints. Guards check in at each point as they go; the dispatcher watches tour progress live and is alerted the moment a checkpoint is missed or runs late.
DialogDispatcher — live map, PTT from desk, incident management, recording playback, and full OTA device control from a Windows PC.
PTT audio recorded server-side per group — including AES-256 encrypted groups — with a per-group record on/off toggle. 30-day retention on Professional. Searchable by group, date, and device from the dispatcher console and web portal.
Push app updates to all devices over the air from the dispatcher console. No physical access to Hytera radios or Android devices required.
Roll app updates out gradually across the fleet — start with a single canary device, trickle to the rest on a schedule, and auto-halt if a release misbehaves. Driven entirely from the web portal, like a private Play Store.
Provision rugged radios in minutes with the Dialog Provisioner. It enrols each handset as Device Owner so the app, its permissions, and every later update apply silently — no taps on the device.
The Windows dispatcher keeps itself current automatically — signed, integrity-checked releases delivered straight from your own server, with no manual reinstalls.
For fleets on managed mobile data, manage the IoT SIMs from the dispatcher — see live and offline status, activate, suspend or resume data, and lock each SIM to a specific handset's IMEI.
Export any radio's location history as KML, GPX or CSV — for Google Earth, mapping tools or spreadsheets — or bundle the track together with its audio in a single ZIP.
Update device configuration — server address, credentials, group assignments, lone worker settings — pushed to devices without user interaction. Send live remote commands too: force a channel change, have a radio announce its battery aloud, or replay its last call.
Run the Dialog PTT server on your own VPS or on-premises hardware. Docker-based, 2 vCPU / 2 GB RAM minimum. Full data residency. Self-hosted guide →
Browser-based admin portal for device management, user provisioning, group configuration, and recording access. No client software required for administration.
Create and manage incidents from the dispatcher console. Recordings auto-link by time and group; attach GPS trails, files, and notes. Export a complete evidence bundle — PDF report, audio, GPS track (KML), and attachments — in a single ZIP.
New recordings, incident changes, and device status updates push to the dispatcher console live — no refresh, no reconnect. Dispatchers always see the current picture.
Hardware-bound device authentication using ECDSA keys stored in the Android Keystore. Prevents credential sharing and unauthorised device substitution.
Spin up an ad-hoc talkgroup on the fly for a job, event, or incident. Drop any devices in, talk, then dissolve it when you're done — no permanent group config. Encrypted by default with its own rotating per-channel key.
Give every incident its own dedicated temporary channel. Pull the responding units onto it in one click so the incident's traffic stays off the day-to-day talkgroups — and is captured together for the incident evidence bundle.
Draw a zone on the dispatcher map around a site or incident. The zone is live — devices inside it are tracked and managed as a unit, with enter and exit events feeding straight into your operations.
When a radio enters an incident zone it's automatically locked onto that zone's temporary channel — and released when it leaves. Responders are always on the right channel without ever touching their radio.
Scope an incident to a geofenced zone, each with its own temporary channel and member list. Run several parallel incidents across a large site — every one isolated to its own area and talkgroup.
Lock a device to a channel from the dispatcher so it can't be switched away mid-incident — enforced on both the radio and the server. Lift the lock with one click when the job is done.
Patch two talkgroups together on the fly so separate teams can hear and talk to one another during an incident — then un-patch them with one click when it's resolved.
