Traditional Telephony Architecture
A look at were WellStar started -
- Low capacity ISDN circuits are dedicated to each phone system
- Segmented Systems that are not enabled for calling between locations
- A high number of systems to manage - required outsourced managed services
- Limited generators & UPS infrastructure
- And limited Disaster recovery capabilities

3. WellStar Communications Requirements
Integrated Solution (voice, video & chat)
One Management Interface for the solution
Cost Savings (reduce calling charges & reduce system management cost)
Reliability & Redundancy (internal communications is critical for patient safety)
Increase efficiencies with staff & reduce travel between locations
Avaya’s Flatten Consolidate Extend (FCE) Model

Business Issues
Integrated Solutions = On-Net Calling & Collaboration (video, voice & chat)
Central managed = Single management interface for all solutions
Cost savings = Intra-office calling & outsourced support services
Reliability = Patient safety
Internal Communications is highest priority (could be the difference between life and death)
Efficiencies & Enhancements = Staff productivity & reduce travel time for meetings
FCE model matches with a centralized SIP trunk solution
Network = Power-over-Ethernet switches, circuit capacity upgrades, QOS policies, SIP trunk build
