A mosaic of every source, composed for command
The name says it: tessera, the tile of a mosaic, and vox, the voice. Tessavox places each source — a map, a drone, a field radio, a desk phone, a commander — exactly where decision makers need it, and keeps it there.
Locked layouts, assigned seats
Pin the map top-left and the drone top-right. Layouts are planned when the meeting is scheduled and applied automatically.
Your data never leaves the room
Video, recordings, captions and accounts stay on your server. No cloud API calls, even for AI translation.
Works with what you already have
Browsers, desktop apps, IP phones, SIP and H.323 systems, existing PBXs, TAK servers and handheld radios.
SPD 8 m/s
HDG 045°Drone-01Aerial feed · flight data overlay
One platform instead of six separate systems
Each capability works on its own. Together they give a command post, an emergency operations center or a trading floor a single, governed communications backbone.
Command video
1080p multi-party conferencing with layouts you control. Browser and desktop clients, SIP and H.323 room systems, moderator controls.

See it from the air, plot it on the map
A pilot presses “Go live” and the aerial feed takes its reserved place in the meeting. At the same moment the drone appears on every TAK map, with its camera bearing and a link to the live video.
- SRT and RTMP streams from our field app and from drone controllers that support live streaming
- Flight data overlaid on the video: altitude, speed, heading
- Automatic recovery after link loss — no operator action needed
A shared language for joint operations
Speech recognition, translation and speech synthesis run on the Tessavox server. Captions appear about one second after a sentence ends; translated voice follows. Handheld radios join through a USB interface — no radio modification.
- Chinese ↔ English captions and translated voice in meetings
- Radio-to-radio translation on the same channel, ~1.5 s after “over”
- Custom terminology lists for military and technical vocabulary
Your phone system, inside the command platform
Every user gets one extension that rings the browser, desktop app, mobile app and desk phone together. Keep your existing PBX — a standard SIP trunk connects both worlds.
- External callers join meeting rooms by whitelist or voice PIN
- Server-side call recording with supervised access and tamper evidence
- Live line monitor — authorized supervisors can listen in
Sovereign by default, auditable by design
Tessavox runs inside your perimeter. Every login, room entry, recording playback and listen-in session is recorded — who, when and from where.
- Role-based permissions and room access rules with PIN protection
- Encrypted web, media and caption connections; private certificate authority
- Ready for your security assessments and penetration testing
Sized from one room to a national command network
Recommended planning capacity per server for concurrent 1080p video, kept well below measured limits. Start with one server, add a GPU for AI translation and many simultaneous rooms, scale out when you need more.
