Enterprise VoIP Telephony & Digital Relay for Central Government (AGE)
Challenge
Modernize mission-critical communication infrastructure across ministries of the Spanish Central Government (AGE), replacing physical fax machines and legacy copper telephony with secure, auditable digital channels.
What it solves
- Secure digital relaying: Replaced physical analog fax infrastructure with RightFax, routing confidential transmissions as encrypted email relays.
- Enterprise VoIP telephony: Hardware sizing, deployment, and security hardening of Dell enterprise servers integrated with LDAP and the ministerial Autentica directory.
What it avoids in production
- Information leaks and misplaced records: Full digital audit trails for sensitive government records without paper-based vulnerabilities.
- Service outages: Enterprise hardware fault tolerance and redundant network routing ensuring 24/7 uptime for essential public services.
