CLIENT
A large not-for-profit provider of education and aged care services headquartered in New South Wales. With more than 20 operational sites and a growing footprint, the organisation required a unified, secure, and modern telephony system to replace ageing infrastructure and improve communication across its geographically dispersed teams.
01
CHALLENGES
The client faced four key challenges as their telephony environment became increasingly fragmented:
Fragmented Legacy PBXs
Each site operated its own onsite PBX system. These legacy platforms were difficult to manage, lacked modern features and frequently failed, disrupting operations.
Rising Telephony Costs
With separate carrier services and ongoing support required at each location, costs were unpredictable and increasingly difficult to justify.
No Centralised Reporting
The absence of a unified platform meant call activity could not be tracked, managed or analysed across the organisation.
Disparate User Experience
Staff had inconsistent tools and processes for call handling, training, and support, leading to inefficiencies and user frustration.
02
SOLUTIONS
All IT delivered a five-part transformation focused on cloud-hosted resilience, centralised control and scalable operations:
Strategic Planning and Needs Assessment
- Conducted site audits across all locations to document existing infrastructure and connectivity
- Engaged with leadership and departmental stakeholders to identify workflow, reporting and support requirements
- Designed a modern, cloud-first telephony solution based on 3CX, built to enterprise standards of reliability and scalability
AWS-Hosted 3CX PBX Architecture
- Structured cabling (Cat6) with enterprise-grade managed switches
- VLANs configured to separate clinical, admin, and guest traffic
- Business-grade dual-band Wi-Fi with WPA3 encryption for staff and guest use
Internet with Redundancy
- Deployed the primary 3CX PBX instance in Amazon AWS Sydney with geographic redundancy in AWS Melbourne
- Consolidated multi-site SIP trunking into a single, resilient platform, eliminating siloed carrier contracts.
- Configured automated failover, backup and disaster recovery using AWS-native services.
- Enforced enterprise-grade security with encrypted SIP signalling, role-based access and managed VPN links for sensitive environments
Seamless Migration and System Consolidation
- Developed a structured, site-by-site migration schedule.
- Ported existing numbers and transitioned users with minimal to no downtime.
- Decommissioned more than 20 fragmented PBX systems, consolidating them into a single unified platform.
Feature Rollout and Platform Enhancement
- Delivered tailored call flows, including IVRs, ring groups, presence management and failover routing.
- Rolled out real-time and historical call reporting dashboards for department heads and leadership teams.
- Enabled advanced telephony tools such as mobile apps, softphones, video conferencing, voicemail to email, and browser-based system management.
Training and Change Management
- Delivered onsite training across all locations, including the “train-the-trainer” sessions to build internal capability.
- Provided staff with user guides, onboarding materials and live support during the transition.
