Dialog PTT is a complete PTToIP platform. Every feature listed below is available today — no add-ons, no premium tiers for core functionality.
Instant half-duplex PTT over LTE, 4G, 3G, or Wi-Fi. Sub-second floor acquisition. Works anywhere with a data connection.
High-quality Opus audio at 24 kbps. Adapts to network conditions. Better clarity than DMR at the same bandwidth.
One-to-one encrypted private calls between any two users. PTT-style instant connect — no ringing, no delay.
In-channel text messaging with delivery receipts. Works alongside voice PTT in the same talkgroups.
DeepFilterNet3 deep-learning noise suppression on TX. Removes background noise before it leaves the device.
Voice-operated transmission using Silero VAD. Hands-free operation for field workers who can't reach the PTT button.
Configurable check-in timer. If a worker misses their check-in, escalation goes straight to the dispatcher.
Accelerometer-based tilt/fall detection. Alerts the dispatcher if a device is horizontal for longer than the configured threshold.
Hardware SOS button support on PTT radios. Instant alert to all dispatchers with device location.
Real-time device positions updated every 5–60 seconds (configurable). Shown on dispatcher map and peer map.
Draw circle or polygon zones on the map. Alerts trigger when devices enter or exit defined zones.
Full location history per device. Attach recordings and notes to incidents. Export PDF incident reports.
DialogDispatcher — full Windows app with live map, PTT from desk, stun/unstun, incident management.
Browser-based admin portal for device management, group configuration, and audit logs. No VPN required.
Push configuration changes to devices over the air. Update GPS interval, audio quality, feature flags — no physical access.
Run the Dialog PTT server on your own VPS with Docker. Full data residency. Upgrade on your schedule.
Primary QUIC transport with automatic WebSocket fallback. Survives NAT, firewalls, and poor network conditions.
