TELCAL Unified Emergency Phone Network

When the Big One hits, TELCAL keeps everyone connected.

The only true unified emergency phone network that bridges every disparate satellite system — Starlink, Iridium, Inmarsat, BGAN, and more — into one resilient, interoperable voice network when normal communications fail.

True Interoperability

One network. Every device. Every satellite path.

TELCAL Unified bridges every major satellite system, vehicle, EOC, and field handheld into a single emergency phone network. No provider lock-in. No silos. Just one network that works when everything else doesn't.

Built for the worst day, not the average one

When the Big One hits.

The major earthquake. The catastrophic wildfire. The regional blackout. When cell towers fall, fiber cuts, and terrestrial networks go dark, TELCAL is already running on the satellite paths that survive — keeping commanders, field teams, and dispatch on a single phone network.

Disaster preparedness isn't a feature of TELCAL. It's the entire design brief.

Capabilities

Engineered to keep talking when nothing else does.

True multi-satellite interoperability

Bridges Starlink, Iridium, Inmarsat, BGAN, and other disparate satellite providers into one unified phone network — no provider lock-in.

Layers on top, never interferes

TELCAL sits as an overlay on existing satellite systems. Your current hardware, contracts, and workflows keep running — TELCAL just makes them talk.

4-digit extensions

Simple, memorable extensions across the entire response team. Dial a teammate the same way whether they're on Starlink, Iridium, or a VoIP desk phone.

Conference bridges & group calling

Spin up incident-command bridges and group calls on demand — coordinate field teams, dispatch, and command from a single conversation.

High security & redundant data centers

Encrypted call routing with geographically redundant data centers built for the moment everything else fails.

Works with the Starlink Portable Hub

Pairs natively with AdaptConn's Starlink Portable Emergency Response Hub and every major satellite phone — drop it in the field and it's online.
