SOLUTIONS BY SECTOR
Built for institutions that can't go dark.
When the network drops, the cloud is unreachable, or a crisis hits, your phone system has to keep working — and keep people safe. Bulwark Voice Suite is sovereign, survivable and self-hosted, with emergency alerting, muster, threat correlation and geofencing built in. Here's how each sector puts it to work.
🛡️
Defence & Military
A Cisco replacement that stays entirely on-base — sovereign, air-gapped, survivable — with base-wide alerting and personnel accountability when it matters most.
Sovereign & air-gapped
Every call, recording and byte stays in-country, on your own servers. Offline licence, no cloud, no phone-home.
Self-hosted · offline
Base-wide muster in minutes
Blast a voice alert to a unit, zone or the whole base; "1 = safe, 2 = need help" gives a live accountability roll.
Emergency alerting · muster
Correlate your own intel
Feed in your sovereign threat/weather sources; new events auto-alert only the personnel near them.
Threat awareness · geofencing
Duress & incident bridge
A panic code spins up a secure conference and pulls command in automatically, fully logged.

Survivable by design
1–4 nodes active-active; lose one and calls keep flowing. Encrypted on every call from first boot.
High availability · TLS/SRTP
Locked-down edge
Allow/deny by IP, subnet or country with auto-ban — shut out scanning and toll-fraud at the perimeter.
IP firewall · audit
🏥
Hospitals & Healthcare
Code alerts that reach the right team instantly, on-call routing that follows the roster, and comms that stay up and compliant through any incident.
Code & mass-casualty alerts
One tap sends a code-blue or mass-casualty voice alert to the right teams, with muster to confirm who responded.
Emergency alerting · muster
On-call follows the calendar
A clinician's calendar drives presence — in theatre or off-shift, calls route to the covering line or voicemail, never a dead ring.
Presence & calendar routing
Ward-level paging
Geofence alerts to a building or ward so only the relevant staff are paged.
Location & geofencing
Compliance-ready
Encrypted by default, call recording with retention and PCI-style pause/mask, append-only audit of every change.

Schools & Colleges
