Emergency phones are only useful if the call gets through.
Blue-light phones, pool phones, parking-garage call boxes, area-of-refuge communications and other emergency endpoints are often scattered across a property or campus, and their legacy lines are easy to overlook.
Critical Line finds those connections, maps where calls go, identifies transition exposure and manages the migration.
Have an endpoint nobody can identify? Tell us.
The hardest emergency line to migrate is the one nobody knew existed.
Stairwells, parking areas, pools, campuses, remote buildings, transportation areas and industrial sites all accumulate emergency endpoints over the years.
Critical Line builds the communication map before anything is cut over.

Build the communication map before you cut anything over.
Locate every emergency endpoint and the service behind it.
Where calls go, what powers the endpoint, and its transition exposure.
Coordinated with monitoring providers, vendors and the carrier.
Every endpoint tested, documented and kept visible after cutover.
Questions we hear first.
Can you locate emergency phones across a campus?
Yes. Mapping scattered endpoints across campuses, garages and remote buildings is the core of Discovery for this use case.
Can current hardware remain?
Often yes. We validate the endpoint against the new path before recommending any replacement.
Can monitoring be included?
Yes. Call destinations, answering arrangements and monitoring are part of the map and the migrated design.
Can elevators be included in the same project?
Yes. Elevator phones, emergency phones and other critical endpoints are usually strongest as one program with one inventory.
What about emergency location information?
Dispatchable location matters, and what a replacement path delivers depends on the endpoint and the service behind it. We confirm that before anything is cut over rather than assuming parity with the old line.
What do you need to begin?
An address is enough. A carrier bill or a list of known endpoints makes discovery faster, but unknown line purpose is expected and is exactly what discovery is for.
